Abstract

The utility model provides a synchronous reluctance motor rotor structure. The motor rotor is formed by multiple circular disc-type rotor punching sheets which are axially and tightly laminated, wherein multiple reluctance grooves are punched in the rotor punching sheets, the surrounding of the reluctance grooves is formed of grids; magnetic bridges are disposed in middle positions of the reluctance grooves of the rotors, and the width of the magnetic bridges is smaller or equal to that of the grids. According to the synchronous reluctance motor rotor structure, rotor structure strength is improved.

Description

The synchronous magnetic resistance motor rotor structure
Technical field
The utility model relates to the alternating current machine technical field, particularly a kind of synchronous magnetic resistance motor rotor structure with special shape.
Background technology
Early stage synchronous magnetic resistance motor is again armature reaction-excited machine, belongs to a machine of synchronous machine.Its feature is there is no excitation winding on rotor, and stator winding is connected AC power and produced magnetic field, because friendship, d-axis reactance there are differences and produce electromagnetic torque, thereby realize energy converting between mechanical.
As shown in Figure 1, the rotor punching structure intensity of this shape is lower, in processing and use procedure, easily causes rotor punching grid place to rupture and affects the result of motor performance.
The utility model content
Technical problem to be solved in the utility model is that a kind of synchronous magnetic resistance motor rotor structure that improves rotor structure intensity will be provided.
In order to solve above technical problem, the utility model provides a kind of synchronous magnetic resistance motor rotor structure, this rotor axially laminates fastening forming by a plurality of discoid rotor punchings along rotating shaft, the rotor punching punching has some magnetic resistance grooves, formed by grid around the magnetic resistance groove, magnetic resistance groove centre position at rotor is provided with magnetic bridge, and the width of magnetic bridge is less than or equal to the width of grid.
Hand over the ratio of axle inductance and d-axis inductance to be called the salient pole ratio in synchronous magnetic resistance motor.And the size of synchronous magnetic resistance motor electromagnetic torque directly is proportional to the salient pole ratio.Therefore salient pole is than being the direct main electromagnetic performance that affects motor.For guaranteeing the salient pole ratio of rotor, the magnetic resistance groove of outmost turns is not provided with magnetic bridge, and the width a of magnetic bridge must be less than or equal to the width b of grid.
Superior effect of the present utility model is: improved rotor structure intensity.
