1 YZRDW series eddy current braking double-speed three-phase asynchronous motor for lifting, is a new type motor developed as the complete set of the lifting unit of the tower crane.
2 This series motor is of constant power adjustable speed The stator of this motor has 6 leadouts; the rotor adopts a set of compound coil line set and the design of the high-speed electrode can be carried out through three external slip rings; and the low-speed electrode rotor winding has been connected into a loop and the high impedance can automatically appear, at this time, it is equivalent that the squirrel cage motor runs
