The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
The switched reluctance motor initially suffered from a lack of effective speed control. It was not until the 1970s, with the emergence of fast-switching electronics within variable speed drives (VSDs), that the synchronous reluctance motor was able to finally come into its own and reach performances comparable to that of conventional induction ...
Cross-section of switched reluctance machine with 6 stator and 4 rotor poles. Notice the concentrated windings on the stator poles. A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. The rotor does not have any windings. It generates torque through magnetic reluctance.
The most significant reason to switch to a brushless motor is a reduction in power required to operate them versus a typical AC motor. [17] In addition to the brushless motor's higher efficiency, HVAC systems, especially those featuring variable-speed or load modulation, use brushless motors to give the built-in microprocessor continuous ...
Line regenerative variable frequency drives, showing capacitors (top cylinders) and inductors attached which filter the regenerated power. A motor drive is a physical system that includes a motor.

Froment's "mouse mill" motor was an early form of electric motor, also known as the Revolving Armature Engine. [1] It has similarities to both the synchronous motor and the contemporary stepper motor. As the mouse mill motor was simple to construct and its speed could easily be governed, it was later used to drive automatic recorders in telegraphy.
