|YD Series variable pole multi-speed three phase asynchronous motor is one of the main series products deriving from Y3 series three phase motor. YD Series variable pole multi-speed three phase asynchronous motor can change the rotational speed to meet the requirements of load state. YD Series variable pole multi-speed three phase asynchronous motor are widely used in industrial and agricultural departments such as machine tools, mining metallurgy, spinning and weaving, printing and dyeing, chemical industry and agricultural machinery, etc.|
Insulation: The motors' insulation system is set to Class F(105K), examined by Class B(80K), which ensure the life span and reliability of the motors.
Site conditions: Motors are suitable for most working environment at temperature from -15°C t0 +40°C and altitude below 1000 meters
Motor protection: Motors can be installed with PTC, PT100 used as winding and bearing temperature measurement on request.
Voltage and frequency: Standard voltage and frequency is 380V 50HZ, and can be set to any single voltage in the range of 200-660V at a frequency of 50 or 60HZ. The motors work well within variations of ±5% from the rated voltage.
Vibration: Motors are designed to vibration class A, vibration class B is available on request.
Cooling and ventilation: The standard cooling method is totally enclosed fan cooled(TEFC) in accordance with IC411 of IEC60034-6. Standard motors are equipped with auxiliary plastic fans.
Winding: 100% Cooper Wire
Protection class: The standard protection class is IP54/IP55, which can be used in humid and dusty environment. Higher degrees of protection is available.
Quality assurance: From the first line of production designing till the finishing procedure, obey ISO9001 documented quality system.Motor quotation
