A recent study, led by Runze Jing, summarized field weakening (FW) control strategies into calculation-based methods, voltage closed-loop control methods, and model predictive control-related methods.

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 ...

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 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 ...

Chinese EV maker BYD has disclosed four patents detailing variable-flux permanent magnet synchronous motor technology.

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 ...

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 ...

To control system operation, motors require a current measurement, which can be achieved using shunt resistors that provide a simple and cost-effective solution. Motors are used in countless consumer ...
