THE MOST POWERFUL VESC YET!! A VESC WITH 300A 75V perfect for electric vehicles, electric boats, electric hydrofoils, industrial applications

The VESC 75/300 is capable of 300A at 75V. This VESC is perfect for electric vehicles such as boats and hydrofoils, as well as industrial applications that operate within a 75V parameter. 

Introducing the amazing VESC® 75/300 Speed Controller.
The VESC® 75/300 is the 7th & very latest edition of speed controllers designed by Benjamin Vedder.

TRAMPA BOARDS LTD has teamed up with the internationally renowned 'YODA of electronics' (Benjamin Vedder) to bring to the world the most advance electronic speed controller ever to be produced! Benjamin's family name is Vedder & the V in the name VESC represents this. VESCVEDDERs Electronic Speed Controller! There have been many ESC's before, but now the VESC officially exists. Benjamin is globally renowned for his incredible electronics and software skills. He has worked tirelessly for well over 7 years fine tuning preceding versions of the globally famous & Trade Marked VESC products & now after teaming up with TRAMPA BOARDS Ltd the development of the VESC SIX and VESC 75/300  has been taken to it highest capability yet. The testing has been completed, with stunning results to boast about & to help us identify any technical and production problems.

The VESC 75/300 is being configured with the brand new Open Source, GPL V3 licensed VESC®-Tool Software:  www.vesc-project.com
The Open source, GPL V3 licensed VESC Firmwares will come pre-installed on the device, allowing us to do extra testing of the device, prior to shipping.
This is the GPL V3 license contract for your reference showing here on the Vesc-Project website 

The VESC75/300 is the most powerful & impressive Electric Speed Controller Benjamin has ever envisioned! It is arguably by far the best general purpose Electronic Speed Controller the world has ever seen so far!! Hydrofoils, crazy E Boarding, performance E-Biking, Remote control of all kinds including Autonomous Vehicles & Robotics and Camera equipemnt (as well as thousands of industrial, scientific & recreational applications) are all about to be revolutionized by using the VESC series of products that will all come to the market soon...

Using the VESC 75/300 in your product  (regardless what it is) will allow you to add any battery delivering up to 75V of max peak voltage (e.g.16S Lithium + voltage spikes). This is the perfect limit to give you incredible performance from your battery driven electric motors. Using the new VESC TOOL Original (which you will get access to once you have made your purchase) or the VESC-App for Android, you will be able to fine tune your performances relevant to your application, while you will see all the real time data that the VESC computes and outputs. Speed, RPM, current consumtion, duty cycle,  battery capacity and state of charge, Wh consumtion and WH regen, estimated range, realtime data graph plotting etc.  Beautiful! All you need is a Bluetooth module to interchange  the data with your phone, computer or tablet. Even firmware updates and configuration can be done wirless now. 

The 75/300 VESC features the following ports and outputs:

- Sensor port for motor sensors (ABI, HALL, magnetic precission encoders)
- CAN Port for CAN communication with other devices and VESC arrays.
- PPM port to connect PPM tranccievers
- COMM port for various kinds of other communication methods like I2C, ADC, Uart. You can use your Arduino or RaspberryPi to control the VESC!
- SWD port to get direct access to the Chipset. Diagnostics, debugging, and real time data.
- SWD port for internal NRF upgrade (landing pad is pat of the PCB)
- AUX port to supply 12V and 5V to external devices.
- USB

The TRAMPA 75/300 VESC comes fitted as standard with TRAMPA's very own & very special Silicone Coated & TRAMPA logo'd cables which are made up of 1036 Strands of Highly Flexible Top quality Copper. These quality details ensure the maximum performance at all times. Attached To the premium copper cables are three genuine Amass XT90 connectors on the battery side allowing you to push up to 300 battery Amps. Using multiple high quality silicone cables on the motor side ensures your power flows to the max. Thicker cables would be hard to bend and would consume more space than necessairy, while multiple smaller cables can be routed with ease to your phase wire connection point while keeping the housing as small as humanly possible.

The VESC 75/300 is installed with a custom Internal Silicone Part & is neatly fitted into the Heat Sink which is a Solid Block of CNC'd  T6 Aluminum which is used for dispensing the heat, offering maximum protection, allowing easy fitting and maximum good looks!The CNC'd 6061T6 Heat sink Box dissipates the excess heat that can be encountered when operating in flat out instances, thus keeping the Unit at a cool operating temperature whilst the CNC housing allows you to attach it to pretty much to anything for easy mounting and even more heat dissipatipn.

The performance of the VESC 75/300, compared to preceding VESC models, is light years ahead! This is demonstrated in the cost, as cheap non effective copies are sold according to their price not their quality. If you want the best performance then stick to the original hardware source - it will save you a lot of money on the long run.

Welcome to a new era for TRAMPA. Though still in the testing stages, the 30hp+ Electric Pro-Kart is is the next big thing from TRAMPA. Our idea with this project is to share our findings in converting a Pro-Kart to be fully electric & compete in speed & power with its dirty combustion-engined equivalent. Below is the story so far.

 

How we got here

The fully working prototype Pro-Kart was donated to TRAMPA by Legendary Racing Driver & Race Team Owner, Lotus Car dealership (Part) owner, Ex-Professional Ballroom Dancer, Luxury Apartment property developer & now unfortunately for him TRAMPA's Landlord - The amazing Mr Kevin Riley.

Kevin is a Gem of a person, with stories to rival Giles Brandwith. He loves spending his time at TRAMPA, hanging with the much younger crew & Ted's Dad, Tweedie.

Tweedie is about the same age as Kevin and is a bit of a 'wheeler dealer', Proper Old Skool kind of guy, he loves a joke & is always trying to get a rise out of you with some elaborate stories... On a regular basis, Tweed runs errands for the TRAMPA crew, what this really means is that he fetches the sausages for the BBQ we have on just about every Friday. Well, Kevin is a big fan of the weekly sausage fest... Kev & Tweed' sit in the corner, smashing a couple of sausage sanies while Drum n Bass, or something equally as loud bangs out the workshop sound system. Anyhow, this kind of scenario is where the first steps of a TRAMPA Electric go-kart were born.

Kevin set us a target of making his Pro-Kart out-accelerate & Lap quicker than the Standard Pro-Kart!



Car Park Testing

As you can imagine, the moment the Go-Kart turned up in the warehouse the crew started poking their fingers around it, trying to suss out where to mount components etc. After only a week or so, the Go-kart had the bare minimum to get moving and was fork lifted into the car park for its first testing. Once placed on the floor by Ted, an eager Dave jumped in the driver’s seat with tablet and VESC-TOOL in hand. Once switched on, Dave proceeded to cautiously drive the Kart forward. The crew stood there in the unknown as Dave disappeared around the corner of the building. An electric whine from around the corner was followed by a now much less cautious Dave tearing around the right-hander towards the crew. He turned around by the TRAMPA HQ door and put his foot down to go for another lap, but instead was met with the realisation that maybe he should not have gone so quickly so soon. The Kart wouldn’t move it turned out that the most expensive part of the Kart had blown - The VESC

Throughout the winter, the process of workshop tinkering and breaking various parts in the car park carried on, the team was eager to get the kart running at its full potential. One of the main issues with the build from the start was overheating, this was resolved by a huge hand-built heat sink that was bolted onto the VESC 75/300, this seemed to solve the problem. However at this point, there was snow on the ground in the car park, so it was hard to tell!

Understandably, the Go-Kart car park racing didn’t go down well with the other residents in Kevin’s warehouse. It had been going on for months and by this point, it was safe to say the Kart was a bit too powerful for the car park anyway.  After several complaints & a neighboring business erecting a fence, we decided it was time we should take it to an official race track.  



1st Day Track Testing

A few phone calls later and we found ourselves with a full track to ourselves. Elk Motorsport in Newark was more than happy for us to turn up with our kart and try it out on a proper track for the first time. 

After a quick drive up to Newark, we turned up at the track with the kart in the back of Teds van. The owners of the Track Tav & Dave took one look and decided it needed some tender love and care before we used it around their circuit. After all the crew had been messing around with the electrics, no one really paid attention to the actual safety of the hardware. 30 minutes later & our electric kart had a fresh set of tyres, all the nuts and bolts tightened and even the steering set up perfectly by a gismo that had lasers! 

This trip consisted of Dave, Ted, Amon & Ben. Dave volunteered to take it for a spin first “I need to test it to make sure it works” He said. The others stood in the pit lane looking jealous as Dave took the debut lap. Grinning from cheek to cheek Dave pulled back into the pit lane. “Need to turn it up a bit!” he shouted from under his helmet”

We spent a good 4 hours or so taking in turns doing laps around the Track. A tablet slipped in the racing overalls made sure we could track all the data from the VESC, we were making changes to values and cut-offs as we went along, gradually turning things up, though making sure we didn’t blow anything. The main issue we found was the batteries, we couldn’t draw enough amps and were only getting around 10 laps out of each pack. Though by the 5th lap the cells started sagging, which is obviously something we want to try and avoid.

Overall the first trip to a track was awesome, we all left stoked with a list of things to make it better. 



The New Battery Pack

After the first track day, we knew we needed to address the batteries on the kart. The original idea was to attach monster boxes as we use on the boards. Though a new product coming out meant we had some modular cell packs that needed testing.  These were 2s6p packs using Molicel 21700 cells we added a few of them together to make a 16s12p. Attaching this battery to the kart was another matter, just like the motor side, we decided to use sheet metal, bent and welded into a trough type shape to house the battery. We then used some mounting clamps bought online to bolt it to the frame. 



2nd Day Track testing 
After the success of the first Go-kart track trip, a lot of people were looped in on the second visit. TRAMPA Head Designer Frank & the man behind the VESC-Project Benjiman Vedder came over for the week. They all needed a trip to TRAMPA HQ, so pairing the occasion with an Electric Kart testing day seemed fitting. Not only the tech crew, but we also had a couple of customers meet us there with their creations; One being an electric miniature Porsche and the other a hovercraft! Unfortunately, the Hovercraft wasn’t able to lap the track, though we were all impressed by the upgraded toy Porsche (Both using a VESC Speed Controller of course). As well as these guys & the majority of the TRAMPA workforce, we were joined by the kart donator himself, ex-racing driver & TRAMPA Landlord Kevin. As well as Kevin's mate who was a professional formula 3 driver, keen to put his petrol cart up against our electric one. It was set to be a good day! 

 

Upon arriving Benjamin immediately had his laptop plugged into the VESC to tune it up. With the new batteries installed we were confident that the sagging was going to be better, the real test this time was to see if field weakening would make the kart faster at the top end. You can think of field weakening as an extra gear once you get to top speed, in theory, we would be able to go around 20% faster.   Again Dave had the first go, he came back after a few laps with a grin on his face. Turns out field weakening worked well. Ted jumped in for the second go, he came back after a couple of laps saying the Go-kart had lost power.  A disadvantage of field weakening is the heat created. The extra power sent to the motor had caused it to overheat. After a quick analysis, the temperature cut-off for the motor was increased and we were back in business. 

The next few hours consisted of everyone taking it in turns to take the kart for a spin, after all, a lot of the crew had not had a go on the track yet and of course Ben, Frank & Jeff needed to have a blast too. Although this didn’t mean perfect controlled testing with the same driving style, it meant the kart was put through its paces so we could monitor the cells, and temperature of all the components. We had brought another 2 sets of Lipo batteries along with the new 21700 pack & chargers, so we had plenty of juice to play with. 

The overheating issue carried on to be a problem throughout the day, the more the off-cut was raised the more the temperature rose. Ultimately this meant the kart has either reached its limit of power and speed or it was time to install another motor. 

On that note, this is up to speed on the current progress of TRAMPA's Electric Go Kart. More to follow...
