The Features of The Permanent Magnet Direct Drive PCP Motor

1. The motor can directly transmit the output torque to the screw pump, eliminating the need for the existing screw pump pumping unit's complicated belt decelerating gear, gearbox decelerating gear, and anti-reverse braking mechanism, reducing the volume and eliminating the trouble of oil leakage in the gear reducer.

2. It can realize online step-less variable speed intelligent parameter adjustment so that the oil production of the screw pump and the oil supply of the oil well is always in the best matching state, to prevent evacuation or under pumping, extend the service life of the screw pump, and increase the oil production. At the same time, it is no longer necessary to repeatedly replace the pulleys and adjust the parameters of the hard work, which significantly reduces the labor intensity of the workers and improves the utilization rate of the equipment.

3. It can realize soft start, soft stop, reverse braking, intermittent work, and variable speed work, which is beneficial to reduce the wear of the screw pump components, prevent the screw from reversing and disengaging, reduce the wear and vibration of the screw pump, reduce the packing oil leakage, and extend the service life of the screw pump.

4. The system is highly efficient and energy-saving. It is in the high-efficiency zone in the entire speed range, which can increase the system efficiency by 30%-60% and reduce the cost of oil extraction. When choosing this system, it can reduce the power consumption by half compared with the Y series motor. The power factor of this motor is close to 1, which can improve the power factor of the grid and eliminate the compensator.

• The direct-drive motor of the screw pump eliminates the need for belts and gearboxes, and the motor directly drives the screw pump to work
• Infinitely variable speed intelligent parameter adjustment to meet the needs of oil well oil condition change and speed adjustment
• Low speed and high torque, in line with the load characteristics of the screw pump, without power reserve
• Soft start, soft stop, reverse braking, intermittent work, no parking brake device
• Energy-saving, the system efficiency is increased by 30%~60%, and the investment can be recovered by saving electricity in one year
• Multiple protections, multiple displays, intelligent management
• Reduce the labor intensity, improve oil well life, optimize the oil production environment, and increase input and output
• Compared with frequency converter + frequency conversion motor: simplified structure, low speed, large torque, large speed adjustment range
