YDFK71-132 Fan specific variable pole multi speed motorDetailed product description：

Overview: The YDFK series aluminum die-casting shell variable pole multi speed fan special motor is a new type of variable pole multi speed three-phase asynchronous aluminum shell motor developed by our company based on the Y series. It has the advantages of high efficiency, large starting torque, low noise, and small vibration. Due to the fact that this series of motors can change the speed of the motor by changing the poles, thereby achieving reasonable power matching and simplifying the variable speed system, it is widely used in air conditioning units, air conditioners, and negative pressure fans for air supply systems, and has been widely used in industries such as textiles, printing and dyeing, and chemical engineering.

The YDFK series variable pole multi speed three-phase asynchronous motor is identical to the Y series in terms of usage conditions, structure, and installation dimensions. The corresponding relationship between its power level and installation size is comparable to similar foreign products, thus it has good interchangeability with advanced products at home and abroad, making it easy to export and use as a backup motor for imported equipment.
The YDFK series variable pole multi speed three-phase asynchronous motor has a rated voltage of 380V, a rated frequency of 50Hz, a protection level of IP55, a cold outlet method of IC411, and F-class insulation. The structure, installation type, and external dimensions of this series of motors are the same as those of the Y series motors.

The YDFK series dual speed motor has a single winding, while the three speed motor has a dual winding. It uses changing the connection of the stator winding to alter the number of poles of the motor, so that the motor can achieve two or more speeds with one or two sets of windings. This series of motor products fully comply with the "Technical Conditions for YaD Series (1P55) Variable Pole Multi speed Three phase Asynchronous Motors". Due to the requirement of variable speed according to the load properties, this series of motors can achieve reasonable power matching and simplify the transmission system. Suitable for various transmission mechanisms that require step-by-step speed regulation, mainly used in universal, combination, and specialized cutting machine tools, as well as mining metallurgy, textile, printing and dyeing, chemical, agricultural machinery and other industries.
