INTRODUCTION

The ZFQZ series DC motor is a series of products developed on the basis of the Z4 series DC motor and drawing on the main technology of the ZZJ-800 series DC motor. The rotational inertia of the motor is 45% and 65% of that of the ZZJ-800 series and ZZJ-900 series, respectively, adapting to harsh working conditions of frequent forward and reverse rotation and frequent starting and braking. The motor has excellent overload characteristics, with its maximum torque and starting torque being 112% and 117% of the ZZJ-800 series and ZZJ-900 series, respectively. The weight of the motor is only 65% of the ZZJ-800 series. The power level of the motor meets the international standard of IEC34-13 "Technical Specification for Auxiliary Motors for Hoisting and Metallurgy". The external dimensions of the motor are in addition to the axial size between the two foot holes; B" In addition, all comply with the IEC72 international standard. The motor can achieve the main installation dimensions consistent with the ZZJ-800 and ZZJ-900 series through a bottom plate, and the corresponding shaft extension dimensions of the ZZJ-800 and ZZJ-900 series can be negotiated, thus replacing the ZZJ-800 and ZZJ-900 series products.
