Description

      Series ZFQZ DC motors are developed on the basis of Z4 Series and ZZJ***0 Series DC motors. The rotating inertia of the motors is *5% and *5% of the motors of Series ZZJ***0 and ZZJ***0 respectively. The motors are suitable for direct and reversal rotation and start and stop in high frequency in a bad working circumstance. The motors are good-overloading. The max. rotating moment and the starting moment are **2% and **7% of the moments of Series ZZJ***0 and Series ZZJ***0 motors respectively. 
The weight of the motors is just *5% of the Series ZZJ***0 motors. The class of the motor power is in accordance with the international standard IEC****3 Technical Criterions of Auxiliary Machine and Hoisting and Metallurgy . Outline mounting dimensions of the motors comply with IEC *2 Standard, except for the axial distance between the mounting holes (dimension B). The mounting dimension of the motors with bottom plates is able to be in compliance with the dimension of Series ZZJ***0 and Series ZZJ***0 motors. Also, the shaft extension dimension of the motors can be customized into the corresponding dimension of Series ZZJ***0 and Series ZZJ***0 motors after discussion with customers. Therefore, Series ZFQZ DC motors can substitute for Series ZZJ***0 and Series ZZJ***0 motors.
