SXDJ motor YR2 (IP44/IP54)

YR2 (IP44) motor YR2 (IP54) motor

YR2 series (IP54) wound rotor three-phase asynchronous motor (frame number 132 ~ 450)

YR2 series (IP54) motor for the closed winding rotor three-phase asynchronous motor, is the latest design of the replacement products. This series of motor power rating and installation dimensions in line with IEC72 international standards. 
This series of motors can be achieved by changing the external resistance of the rotor circuit to achieve good starting performance (at a smaller starting current, to provide a larger starting torque) and a small range of speed requirements. It is widely used in the need for squirrel-cage rotor motor greater starting torque; power capacity is not enough to start the squirrel cage rotor motor, start more frequently and start a long time and the combined electric axis for synchronous transmission and other occasions. Such as: metal cutting machine, crusher, ball mill, compressor, squeeze sugar machine, wire drawing machine, hoist, conveyor belt and other heavy-duty start, short-term operation of the mechanical equipment. This series of motors with high efficiency, overload capacity, low noise, vibration, reliable structure, beautiful appearance, etc., especially for single machine can be supporting exports, and imported equipment with the exchange, has become the company's main export products.

Electrical parameters
1, rated voltage of 380V, rated frequency of 50Hz. According to user needs can also be made 415V, 420V, 440V, 660V and 60Hz and so on. 
2, the stator for the △ connection (3kW for the Y connection), the rotor for the Y connection. 
3, the motor using F-class insulation (winding temperature rise by B-class assessment); cooling method for the IC411; continuous working system (S1). 
4, the motor shell protection class IP54. Which H355 ~ 450 collector ring protection class IP23. Fixed rotor are independent of the top line junction box, the motor wiring more secure, reliable and convenient. If you need other outlet mode when you need to specify the order.
