DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...

Permanent magnet DC (PMDC) motors offer smaller solution size and increased efficiency in applications such as portable vacuums and cordless electric power tools. When designing an isolated power ...

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.

AC induction motors are everywhere, from ceiling fans to vehicles. They’re reliable, simple, and rugged — but there are some disadvantages. It’s difficult to control the speed without complex ...

Preventive maintenance maximizes uptime while controlling costs. Maintenance crews strive to reduce maintenance costs and manage their workloads more effectively. Since DC machines require more ...
