Permanent Magnetic Motor
DESIGN FEATURES
Semi-Direct Drive: Motor sheaves and belts are eliminated, which leads to a higher system efficiency and lower system maintenance costs.
Energy Saving: In addition to enhanced transmission efficiency by eliminating motor sheaves and belts, the motor efficiency is also improved compared to conventional asynchronous motors.
System Reliability and Minimal Maintenance: Other than efficiency, the motor reliability is also greatly improved. Unlike conventional motors, maintenance on the motor itself is minimal.
Space Saver: Compared to conventional motors, our permanent magnetic motors are much more compact in design and eliminate the need of using a motor bracket for pumping unit applications.
Stepless Speed Change: ULT smart control allows the motor speed to be adjusted indefinitely up to the maximal speed.
Green Technology: Extremely low noise and low vibration design makes ULT permanent magnetic motors very environmentally friendly.
TECHNICAL SPECIFICATION
ULT permanent magnetic synchronous variable frequency motor is a low-speed high torque motor specially designed for oilfield pumping units. The traditional belt driven system is eliminated; and the ultra-thin body is used to directly drive the reducer, which is efficient, energy-saving, safe, and reliable.
Conventional (high efficiency) asynchronous motor efficiency is 92%; and the sheave-belt transmission efficiency ranges from 78% to 84%. The total efficiency of a beam pumping unit with an asynchronous motor being the prime mover ranges from 72% to 77%.
ULT permanent magnetic motor efficiency is no less than 93%; and the sheave-belt transmission is no longer required. The total efficiency of a beam pumping unit with an ULT permanent magnetic motor being the prime mover is 93% or higher.
