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. Reluctance motor subtypes include synchronous, variable, switched and variable stepping.
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 .
Switched reluctance linear motors (SRLMs) (also known as linear switched reluctance motors (LSRMs), variable reluctance linear motor or switched reluctance linear machines) are a type of electric machines called linear motors which work based on the principle of a varying magnetic reluctance for force generation. The system can be used in ...
Magnetic reluctance, or magnetic resistance, is a concept used in the analysis of magnetic circuits. It is defined as the ratio of magnetomotive force (mmf) to magnetic flux . It represents the opposition to magnetic flux, and depends on the geometry and composition of an object.
A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.
Serbian-American, engineer and inventor; having worked independently from Ferraris, presented a paper in May, 1888 to AIEE describing three patented two-phase four-stator-pole motor types: one with a four-pole rotor forming a non-self-starting reluctance motor, another with a wound rotor forming a self-starting induction motor, and the third a ...
Lawrenson is considered the father of the switched reluctance motor and associated drive technology. [1] Based on research work that had been carried out jointly by the University of Leeds and the University of Nottingham , in 1980 he and three colleagues (Michael Stephenson, Bill Ray and Rex Davis) established a design, technology development ...
