Three Phase Motor

YD Series Pole-Changing Multi-Speed Three Phase Asynchronous Electric Motor

YD series three-phase multi-speed induction motors are one of the derived series of Y2 series induction motors of our national uniform design; They have the following features: excellent performance, attractive appearance, and good interchangeability for the same kind of products abroad. The motors are designed in three types: double-speed, three-speed, and four-speed. These speed routes can be changed in stages. The engines are widely used in applications in the equipment where the revised rates in stages are needed, such as mechanism, mine, metallurgy, textiles, printing, and dyeing, chemical industry, agriculture, etc.

As one of the three-phase motor manufacturers, suppliers, and exporters of mechanical products, We offer three-phase motors and many other products. Please get in touch with us for details.

YD series three-phase multi-speed induction motors are one of the derived series of Y2 series induction motors of our national uniform design; They have the following features: excellent performance, attractive appearance, and good interchangeability for the same kind of products abroad. The protection class IP44.

The motors are designed in three types: double-speed, three-speed, and four-speed. These speed routes can be changed in stages. The engines are widely used in applications in the equipment where the revised rates in stages are needed, such as mechanism, mine, metallurgy, textiles, printing and dyeing, chemical industry, agriculture, etc. They can also simplify or replace reducing gearboxes in the mechanical drive lines.

General Description

  • YD series pole-changing multi-speed three-phase asynchronous motor is a new type of motor developed based on the Y series. It has the advantages of high efficiency, ample starting torque, low noise, and slight vibration. Since this series of motors can change the speed of the motor by changing the pole, it can achieve a reasonable matching of power and simplify the speed change system.
  • Pole-changing multi-speed three-phase asynchronous motors are divided into multi-winding types and single-winding types.
  • It is to change the number of poles of the motor by changing the connection of the stator winding so that the engine can obtain two or more speeds with one or two sets of windings.
  • The pole-changing multi-speed three-phase asynchronous motor conforms to the standard of JB/T “YD series (IP44) pole-changing multi-speed three-phase asynchronous motor technical conditions (frame size 80~280)”. It is one of the main derivative series of three-phase asynchronous motors.
  • The corresponding relationship between the power level and the installation size of the YD series motors is comparable to the advanced foreign products of the same type. Therefore, it has good interchangeability with advanced products at home and abroad and is convenient for export and as a backup motor for imported equipment.
  • YD series pole-changing multi-speed three-phase asynchronous motor rated voltage is 380V, rated frequency is 50Hz(Can be customized according to users), the protection class is IP44, the cooling method is IC411, and class B insulation is adopted.

Model Description

for example: YD200L2–8

  • “Y” is a three-phase asynchronous motor
  • “D” is multi-speed
  • “200” is the center height
  • “L” is the base length code
  • “2” is the core length code
  • “8” is pole number

Application

It is widely used in various transmission equipment that needs to be applied to step-by-step speed regulation in the fields of machine tools, mining, metallurgy, textile, printing and dyeing, chemical industry, agricultural machinery, and so on.
