Advantages Of DDPM-WO (Workover):
• DDPM-WO has low speed, high torque characteristics, allowing the workover rig to eliminate the angled gear box, and other associated accessories. This directly driven drawworks provides a substantial increase in transmission efficiency, improved lifting capacity, equipment reliability and improved vehicle off-road performance.
• DDPM-WO can achieve almost maximum power under 30% load, and remains constant through a nearly full speed range. In addition, short-time maximum torque capabilities of the DDPM-WO is up to 2-3 times greater. This enables excellent lifting ability, efficiency, and increased processing capacity in an emergency. The DDPM-WO has completely solved the obsolete electric drive workover rig problem of weak lifting capacity and the inability to work under full load.
• The Rotor of the DDPM-WO uses permanent magnet materials. Without power excitation, the rotor has its own strong magnetic field giving better protection for the motor from bumpy off-road transportation which greatly extends the motor’s life.
