Abstract
The invention discloses a kind of single-phase external rotor type switch reluctance motor, belong to switched reluctance machines.Rotor is located at the stator outside, the rotor that is located at the stator outside only by electrical steel sheet be overrided to form, brushless, no winding, no permanent magnet, the inner ring of rotor is provided with several utmost points that formed by several grooves, the stator outer ring is provided with and corresponding several utmost points that formed by several grooves of rotor, constitutes the biconvex electrode structure with rotor; Each of stator is wound with centralized coil on extremely, forms a phase stator winding jointly.Advantage is, its durable, low cost of manufacture firm in structure, easy care have higher operational reliability, have practicality widely.
Description
Technical field
The present invention relates to switched reluctance machines, especially a kind of single-phase external rotor type switch reluctance motor.
Background technology
Traditional rotary switch reluctance motor, adopt the inner rotor core form, stator outside, rotor is interior, stator and rotor are the biconvex electrode structure, brushless on the rotor, no winding, no permanent magnet are wound with centralized coil on each stator poles, the coil on two radially relative stator poles is formed a phase stator winding; Existing external rotor switch magnetic resistance motor is two-phase and the above structure of two-phase.The switched reluctance machines number of phases is many, and its stator line is complicated; Its power inverter quantity of power switches is many, and system cost is higher.
Summary of the invention
The invention provides a kind of single-phase external rotor type switch reluctance motor, it is simple in structure, cost is low, easy to maintenance, long service life, reliability height.
The technical solution adopted for the present invention to solve the technical problems is: a kind of single-phase external rotor type switch reluctance motor, comprise rotor and stator, it is characterized in that, described rotor is located at the stator outside, rotor is overrided to form by electrical steel sheet, brushless on the rotor, no winding, no permanent magnet, the inner ring of rotor are provided with several utmost points that formed by several grooves; The stator outer ring is provided with and corresponding several utmost points that formed by several identical grooves of quantity of rotor, constitutes the biconvex electrode structure with rotor; Each of stator is wound with centralized coil on extremely, forms a phase stator winding jointly.
The invention has the beneficial effects as follows: single-phase external rotor type switch reluctance motor is firm in structure, and the stator line is simple, and its power inverter quantity of power switches is few, reduces system cost, has practicality widely.Can be applicable to electric motor car, mine mechanism etc.
