Crane dedicated vibration motor YZTD series multi-speed induction motors are designed for cranes and crane metallurgical crane supporting the motor. YZTD series motor mounting dimensions and the like, and Y series of the same, two-speed motor or double winding single winding, three-speed motor is a single winding and double winding. YZTD series tower crane with multi-speed three-phase asynchronous motors for tower cranes and other construction machinery and specially developed electric drive cage rotor pole-changing multi-speed three-phase asynchronous motors with speed ratio, the starting current, starting high torque overload capacity and other characteristics. Motor line with the machinery industry "YZTD series of tower crane with multi-speed three-phase induction motor technology" requirements. YZRDW, YZRSW series of construction machinery crane tower crane eddy current brake with two-speed three-phase asynchronous motor Product Overview 1.1 YZRDW series lifting eddy current braking winding rotor two-speed three-phase asynchronous motors, I plant for the starting tower crane lift institutions supporting the development of new motors. This motor has constant power speed characteristics, the stator winding single winding pole, six lead; using a composite rotor coil windings. Extremely low (8 pole) design with three slip rings external series impedance, high-speed internal pole (4-pole) rotor windings are connected into a circuit that automatically presents a high impedance, this time quite squirrel cage motor running. Because in both poles at the rotor has a high impedance, it can guarantee a larger starting torque and variable torque pole switch, can effectively limit the starting current and pole-changing switch current. This motor has a smooth start, pole-switching current small, mechanical shock, simple structure, easy maintenance. The electric motor's patented technology because the novel, the structure is simple, practical, won the seventh Chinese patent invention gold medal. 1.2 YZRSW series lifting eddy current braking winding rotor two-speed three-phase asynchronous motors also have constant power speed characteristics, its stator and rotor are double winding pole-changing way, each six lead. Rotor section with five slip ring structure, which has a slip ring is public ring. Motor high and low speed of the rotor can be accessed through the slip ring external series impedance. Both to ensure a larger starting torque and variable torque pole switch, can effectively limit the starting current and pole-changing switch current. This motor has a smooth start, pole-switching current small, mechanical shock, simple structure, easy maintenance, operational reliability. 1.3YZRDW series motor running at low speed, the rear with appropriate resistance in the rotor circuit, by changing the exciting current of the eddy current brake adjustment brake torque starting or braking process to achieve safety and smooth stepless, so that the lifting mechanism In any case smooth movements or precise load positioning.
