Abstract
A four phase outer rotor switch magnetic resistance motor includes rotor and stator, said rotor is set outside of the stator, and there is not brush, winding, permanent magnet on the rotor, twelve poles or six poles formed by twelve grooves or six grooves are set on the inner of the rotor; eight poles formed by eight grooves which are corresponding with rotor are set on the outer of the stator, and they constructs biconvex pole structure with rotor; centralized coil is winded around the pole plate of the stator, the coil which is relative at radial direction composes a phase stator winding, eight coils composes four phase stator winding. The structure switch magnetic resistance motor can realize the direct drive for fan, electric car, electric roller, without middle transfer device, the reliability of drive system is not only improved, but also the energy spoilage is decreased, the structure is simple and firm, the cost of manufacture is low, and it possesses wide practicability.
Description
Technical field
The present invention relates to switched reluctance machines, especially a kind of four-phase external rotor switch magnetic resistance 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.It is firm in structure durable, low cost of manufacture, easy care, be suitable under abominable outdoor environment, working, can realize the long-life operation that the other types generator is incomparable, it can accomplish to reach on the magnetic circuit on the circuit respectively mutually separate, when certain breaks down mutually, can the assurance system continue safe handling mutually by the excision fault, thereby it has higher operational reliability and fault-tolerant ability, its system regulation performance is good, and the generating efficiency height is at aviation starting/generator system, vehicle launch/generator system, fields such as wind powered generator system have a good application prospect.But if switched reluctance machines is become the outer-rotor structure form, can realize direct transmission to equipment such as blower fan, pump class, electric motor car, mining machineries, and do not need middle switch transition devices such as gear drive, and improved the reliability of drive system, reduced the energy loss of drive system.
Summary of the invention
In view of the problem that prior art exists, the purpose of this invention is to provide a kind of threephase switch reluctance motor of outer-rotor structure form.
Four-phase external rotor switch magnetic resistance motor of the present invention, comprise rotor and stator, described rotor is located at the stator outside, and brushless on the rotor, no winding, no permanent magnet, the inner ring of rotor are provided with by 12 grooves or six 12 utmost points or six utmost points that groove forms; The stator outer ring is provided with and corresponding eight utmost points that formed by eight grooves of rotor, constitutes the biconvex electrode structure with rotor; Each of stator is wound with centralized coil on extremely, and its two radially relative coils of extremely going up are formed a phase stator winding.
Four-phase external rotor switch magnetic resistance motor of the present invention, compare with the rotary switch reluctance motor of traditional employing inner rotor core form, can realize the direct transmission of equipment such as blower fan, pump class, electric motor car, mining machinery, and the switch transition devices such as gear drive in the middle of not needing, not only improved the reliability of drive system, and reduced the energy loss of drive system, it is simple in structure, firm, low cost of manufacture has practicality widely.
