Calibrating a motor controller through test

Sponsored by HBK

In an electric powertrain the motor, inverter, and gear box need to work together to give the desired performance and experience for the end user. Ideally, these components should be designed to work together, but that is rarely the case, as the parts come from a variety of suppliers. All the components have different performance and efficiencies at the different voltages, temperatures, and loadings throughout the range of operation. Fortunately, engineers have a wide variety of variables in the control computer that they can alter to optimize the performance of the powertrain. While computer models are a powerful tool for this, the reality is complex, and engineers need to perform many tests for the best set of variables. It is important to optimize the operation of an electromechanical system for every state and transition in its operation. This is a necessary process and executing it incorrectly will affect the quality of the product.

This paper will discuss the to the complexities and challenges of testing an electric motor closed loop control and provide solutions that can accelerate this process.
