YD series pole-changing multi-speed three-phase asynchronous motor

General description

• YD series pole-changing multi-speed three-phase asynchronous motor is a new type of motor developed on the basis of Y series. It has the advantages of high efficiency, large starting torque, low noise and small 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 type and single-winding type.
• It is to change the number of poles of the motor by changing the connection of the stator winding, so that the motor 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 foreign advanced 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), protection class is IP44, cooling method is IC411, and class B insulation is adopted.
