low noise frequency variable reliable running perfect proformance multi-speed and pole-changing motor
YZD series double-speed three-phase asynchronous motor for metallurgy and lifting is the new-type variable pole high-speed cage-type motor specially developed and manufactured for the variable pole machines according to the metallurgical and lifting requirements. The characteristics of this series motor are as follows: The motor stator adopts the special winding, with two sets of outlet lines. The motor has two speeds, making the metallurgical and lifting machines have two speeds: High speed and low speed; The speed ratio has 11 kinds. The high speed is for the normal lifting and traveling and the low speed for the starting, slight starting and slow positioning of the machine (accurate positioning). This series motor has the performance advantages of small starting current, large starting torque, small switching current, small mechanical impact, strong overload capacity and so on; Furthermore, since this series motor is the squirrel-cage rotor without electric brush unit, it is not necessary to add the speed adjustment unit and the control system is simple. The structure of the motor is simple and it can be maintained conveniently, it is the ideal drive for the metallurgic and lifting machines. This product is widely used in the industries such as metallurgy, lifting, water conservancy and power and so on.
