Name: VESC Maxim 120V
SKU: 661
Availability: InStock

The VESC Maxim is a feature-rich brushless motor controller which can provide up to 30 kW of continuous power when cooled appropriately.

An on-board STM32F405 micro-controller running open-source VESC software enables precise motor control alongside configurable custom applications and scripting. The VESC Maxim also has an ESP32-C3 Wi-Fi and Bluetooth-module that allows wireless connections from VESC Tool.

The VESC Maxim 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.

To protect against moisture and dust ingress the VESC Maxim is fully potted and features a 39-pin automotive connector. The 39-pin connector supports a breadth of external communication interfaces and auxiliary power output which enables easy integration with many different systems and peripherals. This includes items such as lights, indicators, throttles, brakes, sensors, GPS/GNSS and communication devices all which can be managed by the VESC Maxim.

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 pins of the VESC Maxim 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.

An integrated IMU with a 3-axis accelerometer and 3-axis gyroscope eliminates the need for external motion-sensing modules.
