The purpose of this application note is to illustrate a software-based implementation of sensorless, field oriented control for permanent magnet synchronous motors using Microchip digital signal ...

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.

Changing the orientation of rotor magnets on the fly lets a special kind of induction motor run directly from ac lines. The quest for energy efficient electric motors has generated a lot of ...

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, ...

Three-phase brushless motors offer many benefits including economy, reliability and high efficiency, but also exhibit poor dynamic performance. By implementing proper control algorithms (such as field ...

Stepper motors are synchronous motors that step at the pulse rate of the driving signal. For the motor to move quickly, the stepping rate must be fast. However, because of motor and load inertia, the ...
