Abstract

The paper presents a new type of electronically-switched doubly-salient permanent-magnet (DSPM) small motor for household appliances. Its basic structure is similar to that of a switched reluctance motor, except for the presence of high-energy PMs inside the rotor poles. Electromagnetic torque is thereby developed in much the same way as in PM brushless DC motors but with an important cogging torque component required for holding the rotor stationary when the power supply is switched off. A prototype of the new DSPM small motor is designed and nonlinear finite-element analysis made to investigate its static characteristics

Electric motor

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

AC motor

An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings.

DC motor

A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motors widely used, as they could be powered from existing direct-current lighting power distribution systems.
