Sticking to the design concept of developing AC traction motor, HH is engaged in research and development of drilling motor with a large extent of constant power to improve the drilling efficiency and decrease the drilling cost. The stator adopts preformed winding and forms a solid complexity after being varnished under VPI vacuum pressure. The rotor is of a squirrel type structure with high strength, which enables the drilling rig operate reliably in severe environment. Besides, the rotor is of small rotational inertia, improving the acceleration and deceleration performance of drawworks and reducing the energy consumption during acceleration and deceleration
Providing high efficient and energy-saving motor with the power ranges from 30 KW to 4500 KW.
Providing drive motor of all series with drawworks, drilling pump, rotary table, top drive device of ZJ10DBS~ZJ120DBS drilling rig, and interchangeable (installation dimensions) with similar products at home and abroad.
Providing direct-driving top drive motor, direct-driving drawworks motor and direct-driving mud pump motor for various direct-driving devices, featured with large torque, low rotating speed, low noise and high efficiency.
Providing HTZ series DC drilling motor for ZJ40D~ZJ70D drilling rig, and interchangeable (installation dimensions) with similar products at home and abroad.
