of the rotor (rotating)

1,the three-phase asynchronous motor rotor core: Role: as part of motor magnetic circuit and rotor winding is placed in the core slot. Structure: the materials provided with the stator,by 0.5 mm thick silicon steel sheet coining,overlying and become,silicon steel cylindrical blunt with uniform distribution of holes,used for rotor winding. Usually lagging in the silicon steel sheet electric vehicle motor with the stator iron core circle to punch the rotor core. General small asynchronous motor rotor core being connected directly on the shaft,large and medium-sized asynchronous Motor rotor (more than in 300 ~ 400 mm in diameter) of the rotor core,with the aid of and pressure on the axis of the rotor bracket. 2,the three-phase asynchronous motor rotor winding Function: cutting the stator rotating magnetic field induced electromotive force and the current,and form the electromagnetic torque and make the motor rotation. Structure: divided into squirrel cage rotor and rotor winding.www.dongfeng-motor.com (1) squirrel cage rotor,rotor winding by the insertion of the rotor slot dogan conducting bar and two circular end ring. If remove the rotor core,the appearance of the whole winding like a cage, Therefore calls cage windings. Small cage motor adopts cast aluminum rotor winding,for more than 100 kw motor adopts copper bar end ring and copper welded together. 2 wound rotor type: winding and rotor winding of the stator winding is similar,is also a symmetrical three-phase winding,generally pick a star,three line received a shaft head of collector Ring,and then through the brush with the external circuit. Characteristics: the structure is complex,so the application of wound rotor motor is widely squirrel-cage motor. But through the collector motor fan ring and brush in series with rotor winding circuit in the additional resistance and so on Components,to improve the asynchronous motor,braking performance and high performance of reason in smooth speed regulation requires a certain range of equipment, such as cranes,elevators,air pressure Shrink machine such as above.
