Name: VESC Duet
SKU: 585
Availability: InStock

The VESC Duet is a high-power dual brushless motor controller which can provide a total of up to 8 kW of continuous electrical power across two motors when cooled appropriately.

An on-board STM32F405 microcontroller running open-source VESC Software enables precise real-time and fully independent control of two motors alongside the configuration of custom applications to control them.

The open-source firmware supports current, speed, duty cycle and position control over CAN-bus, UART and USB. Throttle configuration using analog or PPM input for common electric vehicle applications can also be done directly from VESC Tool without the need for writing code. It’s breadth of external communication interfaces enables easy integration with many different systems.

The Duet has an ESP32-C3 Wi-Fi and Bluetooth-module that allows wireless connections from VESC Tool.

An integrated 4 GB memory chip allows logging data directly to the device. Reading and analysing the logs can be done over USB, Wi-Fi or Bluetooth from the desktop-version of VESC Tool. If a GNSS-receiver, such as the BE-220 module is connected to the UART-port the logs can also collect position-information. VESC Tool allows viewing this position-information on a map synchronized to the other data in the log.

Both the main STM32F4 microcontroller and the ESP32-C3 support the LBM scripting language that can be used to develop and debug advanced custom applications directly from VESC Tool, using all inputs, outputs and communication interfaces available on the Duet.

The duet supports both sensorless and sensored brushless motor applications with full sinusoidal Field-Oriented-Control enabling quiet, precise, and powerful motor dynamics. Advanced High Frequency Injection (HFI) allows using many types of motors with full torque without position sensors from standstill, eliminating the need for sensitive position sensors in harsh applications even when full performance from zero RPM is required.
