A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

Controller manufacturers are improving features such as motor protection and brushless dc commutation. One operation of all motors, whether powered by ac or dc, calls for a controller. The simplest of ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

Everybody agrees: motors and their control electronics were not created as equals. They live in two different environments. Electronic controls enjoy the safer, cooler, and more centralized enclosures ...

Electric motors, which convert electrical energy into mechanical energy, play an essential role in a variety of industrial and robotics applications. Given that electric motors account for ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

AutomationDirect has added new NEMA 4X AC drives to their IronHorse brand of drives. These new high-performance VFDs support four control modes including V/Hz, slip compensation, sensorless vector, ...

Elektor International Media sent me a copy of Martin Brown’s book, Power Electronics in Motor Drives: Principles, Application and Design. Brown worked with Siemens UK for almost 30 years and designed ...

Electric motors are ubiquitous in industrial applications. Whether it is a DC type, an AC type or a special type like a stepper motor or brushless DC motor, electric motors play a vital role in the ...
