Zfqz, Z4, Zzj-800 806 810 812 814 Series Metallurgical DC Motors for Rolling Mill, Crane, Roller Table, Flying Shear

1.Brief introduction
ZFQZ Series DC motors are developed on the basis of Z4 Series and ZZJ-800 Series DC motors. The rotating inertia of the motors is 45% and 65% of the motors of Series ZZJ-800 and ZZJ-900 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 112% and 117% of the moments of Series ZZJ-800 and Series ZZJ-900 motors respectively. The weight of the motors is just 65% of the Series ZZJ-800 motors. The class of the motor power is in accordance with the international standard IEC34-13 Technical Criterions of Auxiliary Machine and Hoisting and Metallurgy . Outline mounting dimensions of the motors comply with IEC 72 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-800 and Series ZZJ-900 motors. Also, the shaft extension dimension of the motors can be customized into the corresponding dimension of Series ZZJ-800 and Series ZZJ-900 motors after discussion with customers. Therefore, Series ZFQZ DC motors can substitute for Series ZZJ-800 and Series ZZJ-900 motors.
