Product Description

Applicable scenarios

YD series installation method

The rated voltage of the YD series variable pole multi speed three-phase asynchronous motor is 380V. The rated frequency is 50Hz. The protection level is IP44. The cooling method is IC411. The fan self cooling adopts F-class insulation. The YD series dual speed motor has a single winding, and the three speed motor has a double winding. It uses changing the connection of the stator winding to change the number of stages of the motor, so that the motor sleeve or two sets of windings can obtain two or more speeds. This series of motor products fully comply with the "YD series (IP44) variable pole multi speed three-phase asynchronous motor technical conditions". Due to the fact that this series of motors can change the speed in stages according to the requirements of load properties, it achieves reasonable power matching and simplifies the transmission system. The sentence is:. Suitable for various transmission mechanisms that require step-by-step speed regulation, mainly used in universal, combination, specialized cutting machine tools, mining metallurgy, textile, printing and dyeing chemical, agricultural machinery and other industries.

1. The maximum operating altitude is 1000 meters. Customized solutions are available for applications at higher altitudes.

2. The maximum ambient air temperature is 40 °C. Customization is available for applications requiring higher temperatures.

3. The power frequency of ex-proof AC motor is 50Hz(60Hz) ± 1%.

4.The operating voltage must vary within a range not exceeding ±5% of the rated voltage.

5.The ex-proof AC motor rating is continuous duty S1.
