Full-voltage, single-speed motor starters: Single-speed squirrel-cage motors have starters that fall into two categories: full-voltage or across-the-line starters; and reduced-voltage starters.

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 ...

Synchronous motors have a stationary magnetic field relative to the rotor. Permanent magnets or field windings through slip rings create the field. Induction motors have a rotating magnetic field ...

Automobile lovers have been steeped in the language of the internal-combustion engine for so long that the inexorable switch to electrification requires a tune-up of our knowledge base. Many of us are ...

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 ...

The power of a synchronous motor depends directly on the load angle: the greater the load angle, the more torque, which determines the power by the speed specified by the input gear and the ...

There is a constant need and desire throughout the HVAC industry to spur innovation and create new products and ideas that can redefine the marketplace. In the realm of motors, the permanent magnet ...

Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...
