YR(J) series wound rotor three-phase asynchronous motorDetailed product description：

YR (J) series wound rotor three-phase asynchronous motor

1、 Scope of application
1.1 The technical specifications of the YR series wound rotor three-phase asynchronous motor (hereinafter referred to as the motor) comply with JB/T7119-93 YR series wound rotor three-phase asynchronous motor.
The 1.2 YR series wound rotor three-phase asynchronous motor adopts a wound winding type, which can provide a large starting torque at a small starting current and adjust the speed within a certain range. Widely used as mechanical power equipment in situations where the starting time is long and the starting is frequent, requiring small-scale speed regulation and large starting torque.
The enclosure protection level of this series of motors is IP44, and the cooling method is IC141.
1.4 When the power of the stator winding of this series of motors is 3 kW, it is connected to the Y terminal. For other powers, it is connected to the △ terminal. The rotor winding is connected to the Y terminal.
