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 ...

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 ...

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 ...

Nidec Corporation (TSE: 6594; OTC US: NJDCY) (the “Company” or “Nidec”) announced today that it has launched for the US market SynRA (Synchronous Reluctance Motor with Aluminum Cage Rotor), 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 ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

ABB has created a liquid cooled synchronous reluctance motor series that achieves IEC international efficiency class 5 (IE5). It brands its synchronous reluctance motors ‘SynRM’, and is offering ...

The importance of energy efficiency is reinforced by the fact that compressed air systems are significant energy consumers.
