Lifting motors are currently more commonly used in the YZR and YZ series, and the old lifting motors are JZR2 and JZ2 series. YZR three-phase asynchronous motor for crane motor is used to drive various types of lifting and metallurgical machinery and other similar equipment, with large overload capacity and high mechanical strength, especially for those short-term or intermittent operation, frequent start and brake, overload and significant vibration and impact of mechanical equipment.
YZR crane motor insulation grade is divided into F and H and two, F class is suitable for the ambient air temperature does not exceed 40℃ in general places, H class is suitable for the ambient air temperature does not exceed 60℃ metallurgical places. Motors with both insulation classes have the same parameters.
YZR crane motor has good sealing, the motor protection grade for general places is IP44, and the motor protection grade for metallurgical places is IP54. The rated frequency of the motor is 50Hz and the rated voltage is 380 V.
The working system of YZR motor is S2, S3, S4 and S5, and the reference working system is S3-40%.
YZR crane motor can also be equipped with a variety of sensors, a variety of brakes, a variety of thermal protection devices and heating belt, etc., can withstand frequent starting, braking, overload, reversal, overspeed, impact and vibration, and can work in metal dust and high temperature environment, suitable for driving a variety of lifting machinery and metallurgical machinery.
