Traction Motor Sensing and Control | New Training Module

A traction motor creates rotational torque which is transmitted through a reduction gearset and final drive assembly. Speed and direction of the traction motor are determined by the power electronics controller, which is based on commands from the vehicle driver.

A crucial part of this process is determining the absolute position of the traction motor and its direction of rotation.

In the latest addition to our EV Traction & Auxiliary Motors course, we take a deep dive into the various sensing elements used in traction motors, where you will discover how high voltage current is applied and regulated to each of the phases within these electric machines.

The topics covered in this training module include:

• How speed and direction of the traction motor is calculated and executed
• The operation of resolvers and their implementation within the traction motor
• Current flow through the numerous IGBT (Insulated Gate Bipolar Transistor) circuits
• The operation of the HV rectifier circuit used during regenerative braking

This module will be the latest addition to our growing library of over 350 technical training videos, covering the following key areas:
