ZYD800-4 DC Motor for Oil Drilling Machine
This type of motor can be applied as mud pump motor， turntable motor or winch motor for DC electric-driven drilling machine. Installation dimension of the motor is similar with foreign DC drilling machine (such as American GE752ARB3 series motor)， and it can replace the motor of imported oil drilling machine.
It adopts advanced international manufacture and Kapton insulation structure， with full-laminated base that is in line with advanced domestic level， thermal press and formation techniques for large cross sectional coil， helical groove for commutator， oblique brush holder， stator welding connection， integrated VPI insulation treatment on stator and rotor. Commutator riser applies advanced structure and manufacture process such as TIG welding.
Motor can be divided into various types such as ZUD800-4 (right side) and ZYD800-4A (left side)， as per the different direction of junction box (view from drive end).
Main features of motor: positive pressure explosion-proof， high torque， great current， wide range of constant-power speed regulation; good universality， free-maintenance， high efficiency and high reliability.
Type：JD139（600kW）
Full-laminated base without shell
It can improve motor transitional process and commutation performance of pulsating current;
Grooves of base used for inserting iron core of main pole are ensured by fixture， which can guarantee equal accuracy of main pole. Thus， quality of stator assembly can be improved.
Even magnetic circuit can decrease difference of motor speed characteristics.
Matching surface between base and coil of main pole is plane surface， which can not only simplify coil manufacture， but also improve heat dissipation condition for the coil.
