A recent study, led by Runze Jing, summarized field weakening (FW) control strategies into calculation-based methods, voltage closed-loop control methods, and model predictive control-related methods.

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...

The field-oriented control (FOC) approach offers many advantages compared to other control strategies used with electric motors. Among the most significant benefits is the fact that FOC offers precise ...

The problems associated with rare and difficult-to-obtain materials – as used in motors that power EVs as well as batteries – provide a good reason for focusing on recycling and finding alternatives.
