Abstract
This invention relates to a synchronous motor core, in which, the motor includes a rotor or a stator, the stator includes a framework coil and coil cores surrounding it and at the internal cavity of the framework, the rotor includes an alnico and a rotor core surrounding it, the coil core and the rotor core make up of an integral synchronous motor core, the rotor core is a thickened one composed of a rotor core connecting with a enhanced torque plate, thickness of the alnico is equal to or larger than that of the rotor thickened core, which is connected with the coil core in rivet connection, welding and lock. Advantage: the output moment of the motor is increased greatly without changing parameters of the motor structure, exterior sizes and framework coil, besides, the applied sphere is enlarged that can replace the claw-pole synchronous motor used in microwave ovens and pressure electric cookers.
Description
Technical field
The present invention relates to a kind of kit field of synchronous machine, especially relate to a kind of described electric machine iron core thickness of local increase that under described synchronous machine structure and the constant prerequisite of overall dimension, adopts to increase the synchronous machine iron core of described synchronous machine output torque.
Background technology
The cracked polar type synchronous machine comprises rotor and stator component, and described rotor and described stator apparatus are in a described motor housing.Described stator comprises a shaped framework coil and described shaped framework coil is peripheral and the iron-core coil of skeleton inner chamber; Described shaped framework coil is called stator coil again; Described rotor is that the magnet steel of permanent magnetic material making and the rotor core of described magnet steel periphery constitute by permanent magnet.The iron-core coil of existing cracked polar type synchronous machine and rotor core constitute a synchronous electric machine iron core, and are shaped by the punching of the steel plate of uniform thickness, as shown in Figure 3.
Described shaped framework coil be stator coil after energising, described rotor core just produces the armature rotating magnetic field, for described rotor output torque, described rotary speed of rotator is a synchronous speed.The size of described rotor output torque is decided by the magnetic field intensity of described armature rotating magnetic field and the described rotor of being made by permanent magnetic material.
Thereby, existing cracked polar type synchronous machine under described rotor and described stator structure and overall dimension and the constant prerequisite of material properties thereof, the output torque that can't increase described motor.
