YZP series hoist VVVF three phase induction motors are squirrel-cage rotor motors. They integrate advantages of traditional hoist motors and variable frequency motors, they do not only resist frequent starting and braking, overload, regressive rotation, exceeding speed, shock and vibration, but they can also operate under variable frequency controlled conditions. The motor抯 rated frequency is 50Hz, rated voltage is 380V. Variable frequency ranges from 5 to 100Hz. Variable frequency electromagnetic wire is used to strengthen the motors?insulation structure, letting the electric motor operate reliably under frequent voltage shock. The cooling method of the motors is forced ventilation. This ensures a more efficient heat transfer in a wide frequency range. The motors?insulation class is F and H, and protection class is not less than IP44. The mounting dimensions are the same as those of YZ and YZR series to facilitate substitution. It will be our pleasure to send you additional information.
