The STR-500 is not just any motor controller; it is the gateway to the future of vehicle control. With an impressive 40+KW power capacity (680A peak!), running the latest FOC code base from the renowned Benjamin Vedder, this controller stands in a league of its own. It comes equipped with pretty much everything you could ever need, a variable MCU controlled DC-DC converter (6-24V, 15A) to allow you to be able to plug in & power your onboard electronics, as well as a fully equipped IO-board plus a VESC-Express module featuring  permanent logging & GPS-reception with high-speed wireless connectivity are all built in & integrated onto the device. Therefore, the STR-500 is the very first device deserving the title of "Vehicle Controller."

The STR-500 project took shape during the pandemic. Our goal was clear - to achieve 500-600A output power while implementing 100V rated Mosfets. Unlike other brands, we refuse to resort to over-advertisement, referring to Phase Amps that can only be used for short bursts of high currents at low RPMs/speed. Instead, we prioritize delivering continuous power throughout the full RPM range that you can reliably depend on. To achieve this, we utilized four parallel Mosfets, each with a 1.1mOhm resistance, on a 6 Layer PCB with 3Oz of copper on all layer. This design ensures very efficient & short current paths to the output terminals, resulting in a very low overall total resistance. Moreover, we integrated 12 shunts & 12 shunt amplifiers, enabling precise current measurements & compensation for minor variations in current flow along the current paths. The STR-500 power stage is equipped with top-notch electrolytic capacitors, rated for 10,000 hours & having a very low ESR (Equivalent Series Resistance). In addition to these, we've integrated 40 high-frequency ceramic capacitors placed strategically next to each Mosfet. This distinct feature sets the STR-500 apart from other designs suffering from improper capacitor placement or inadequate numbers of capacitors, which often lead to excessive noise and consequently subpar motor control.

The power stage of the STR-500 is coupled with a cutting-edge STM32F405 driven logic stage, incorporating individual high-quality gate drivers to enable high-frequency switching. Unlike many competitors who compromise by opting for cheaper gate drivers pushed to their limits, our approach ensures a superior switching frequency, reaching far beyond the typical 20Khz limitation found in such designs. Up to 35Khz switching is very doable! We refuse to settle for anything less than unleashing the full capability of the drive system. Completing the exceptional performance of the STR-500, the logic stage is enriched with a 9-axis IMU (Inertial Measurement Unit) capable of motion, G-Shock & 3D orientation tracking.

The DC to DC Power Converter: Anticipating the needs of various vehicles, we integrated a versatile STM microprocessor controlled DC to DC converter with variable output voltage (6-24V), current control & very effective fast acting short circuit protection. Capable of delivering up to 15A of current, this converter provides stable power to your essential components such as headlights, tail lights, indicators, displays, USB charge port & much more. Its design allows for easy replacement in case of any issues, ensuring a hassle-free experience for your next project. 100A spikes when switching on a H7 head light - no problem!

The Input-Output Board: Complementing the DC to DC converter, the STR-500 comes with an integrated IO-Board boasting a range of functionalities, including five switchable outputs for 6-24V, one static output for 6-24V, a switchable 5V, 3A output, a static 5V output, 8 protected ADCs, GPIOs, 2x UART, CAN, PWM, SPI, I²C, & USB and to top it all off, we've added the popular VESC-Express module for seamless permanent logging to an SD-Card & of course GPS antenna connectivity, high-speed wireless connections via Wi-Fi & BLE for fast logging data transfer!!! WoW!

Extruded Anodised Housing & optional integrated Heat Sinks: The STR-500 has a custom made extruded then precision CNC'd aluminuim housing with a nice hard anodization surface treatment. Acting as a heat sink, whilst preventing water ingress, it protects against corrosion of the wire connections giving long life expectancy. With its unique cable protrusion systems on both ends, you can effortlessly feed any cable into the housing, no matter how bulky the connector on the cable ends. This setup creates a certified IP 66 seal against the elements, securing all connections safely inside the controller. To maintain pressure balance & to prevent the ingress of water over time (suction effects), we've added a properly sized pressure equalization valve. The housing is easily attachable to a larger heat sink, fitting perfectly into the frame of a Surron or Talaria Electric Motor bike & were already pleased to announce with a water-cooled heat sink option coming soon.

Setup Made Easy: Through TRAMPA & VESC we will develop VESC-Packages, taking care of all the hard work for you. Just like apps on your smartphone, VESC-Packages will run seamlessly on the STR-500, offering a Plug-n-Play integration with your Surron or Talaria bike. These tailor-made software packages include motor settings, IO settings & app settings, ensuring a smooth & customized experience. For added convenience, a dedicated cable harness for your bike, boat, kart, trike, what ever your application will soon be available.
