INTRODUCTION

The HZJ series DC motor is a high-power DC motor developed for petroleum electric drive drilling rigs. The motor adopts internationally advanced motor manufacturing technology and the main pole coil is hot pressed. Advanced mechanisms such as frame steel plate compression welding, steering gear spiral groove, oblique brush holder, and steel wire binding. The main characteristics of the motor are: positive pressure explosion-proof, high current, high torque, wide range of constant power speed regulation, good universality, maintenance free, high efficiency, and high reliability. Its external installation dimensions are the same as those of foreign DC drilling machines and can replace imported drilling motors. This motor can be used as a DC motor to rotate the mud pump motor, rotary table motor, or winch motor of a drilling rig.
