This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

This month marks the 50th year since ABB’s Low Voltage Variable Speed Drive (VSD) was first brought to market.

Somewhere in most engineering educations, there’s a class on induction motors. Students learn about shaded-pole motors, two-phase and three-phase motors, squirrel cage motors, and DC-excited motors.

Demand for low-cost, robust motor drives has spurred increased use of sensorless vector control of induction and BLDC motors in everything from consumer Demand for low-cost, robust motor drives has ...

Chances are, the HVAC system in your house uses a single-speed induction motor to power its fan, and the Department of Energy (DOE) wants to change that. The nation’s energy watchdog wants to replace ...
