Detailed description of YZD series two-speed three-phase asynchronous motors for lifting
YZD series two-speed three-phase asynchronous motors for lifting are a new type of pole-changing variable speed cage rotor three-phase asynchronous motors specially developed and manufactured for the electric drive of various hoisting machinery.
The characteristics of this series of motors are:
It can make the hoisting machinery have two speeds, fast and slow, and the speed adjustment ratio is large. There are 7 speed ratios available, from 1:2.5 to 1:8. The fast gear is used for normal lifting and walking, and the slow gear is used for micro-movement and accurate positioning. It is especially suitable for those large and medium-sized production lines and lifting and transportation occasions that require precise positioning. This series of motors adopt advanced far-pole-ratio speed regulation technology, with low starting current, large starting torque and strong overload capacity. Moreover, because the motor is a squirrel cage rotor motor, there is no brush device that is easy to wear, and no additional speed regulation device is needed. Therefore, it has the characteristics of simple use and convenient maintenance. It is the ideal power for hoisting machinery and has superior performance that the YZR series motors cannot match. The rated voltage of the motor is 380V and the rated frequency is 50Hz.
The enclosure protection class of the motor is IP44, and the insulation class is F. The standard duty system of the motor: S3-40% at high speed and S3-25% at low speed.
The installation dimensions and overall dimensions of the motor are the same as those of the YZ series motors.
