The traction motor drive design and development project for electric vehicles began in 2015 with the support of the Vice Presidency for Science and Technology. The control system of the drive utilizes a microcontroller for processing received data and executing control algorithms.
The control software is implemented as a state-machine, handling data processing and conversion while protecting the drive components and motor from various factors such as high temperature, overcurrent, overvoltage, undervoltage, and excessive motor speed.
The control core is configured for vector control of induction and permanent magnet motors. In addition to conventional functions, the control system incorporates specialized features for traction motor operation, including:
- Operation beyond the rated speed,
- Power reduction in case of faults before complete drive shutdown, and more.
The communication between the traction drive control system and VCU is established via the CAN protocol.
