Specifications

Adapt to AC-DC-AC electric-drive rig, apply to drilling rig rotary table, drawworks, mud pump, etc.

LMMYJ23 Variable Frequency control speed asynchromous series drilling motors

 

 YJ23 cage frequency control speed asynchronous motor, adapt to AC-DC-AC electric-drive rig, apply to drilling rig rotary table, drawworks, mud pump, etc. The main features of the motors are as follows: plus pressure explosion-proof, high current, large torque, wide range constant power speed regulating, free maintenance, high universality, efficiency and reliability. Their outline installation dimension is strictly in accordance with that of imported AC oil drilling motor. The oil drilling motor can be used instead of the imported one. They can function as slurry pump motor, rotary table motor and winch motor of AC electric drive drilling machine.  The motors are divided into two types,according different position of terminal (see from drive end) .
