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.

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.

Combining the advantages of permanent magnet and induction motors, new synchronous reluctance motors (SynRM) offer potentially breakthrough technology for variable speed drive (VSD) and motor packages ...

The basic operating principles of SynRM machines. The advantages SynRM machines offer over switched reluctance motors. How the latest advances in SynRM design are steadily improving the motors’ ...

At a location in Europe, it is necessary to supply 300 kW of 60 Hz power. The only power sources available operate at 50 Hz. It is decided to generate the power by means of a motor-generator set ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

In May 2025, ABB broke its own world record for energy efficiency in large synchronous electric motors. The new motor, designed in line with its Top Industrial Efficiency (TIE) initiative, is destined ...
