This Low-Voltage Motor Controller for 2/3 Wheelers reference design features a traction motor inverter capable of driving motors up to 3kW at 48V, providing a complete demonstration platform for motor control applications. Deliverables include inverter hardware design files (schematics and Gerber) and peripheral sample code. The application accelerator unit (AAU) handles core field-oriented control (FOC) functions, complemented by application-level software (ASW) generated via MATLAB-based model development for system management. GreenPAK™ ICs support phase overcurrent protection and signal level shifting, while flux concentrators enable accurate phase current sensing. Typical applications include low-voltage traction drives for electric 2- and 3-wheelers such as e-scooters, e-bikes, and e-rickshaws.

Features

The power stage can drive up to a 3kW motor.
Support is available to scale the 48V power stage of the inverter, as per customer requirements.
GreenPAK ICs are used for low BOM count phase overcurrent fault detection.
The PMIC enhances safety and reliability, meeting ASIL B standards for critical automotive applications.
