1. High transmission efficiency.
2. In comparison to conventional drive head, at the same condition the percentage of energy conservation is about 15%.
3. Electric regenerative braking is safe and reliable. Due to the use of the permanent electric regenerative motor drive, after the motor stops, the sucker rod releases the torque to drive counter-rotation of the rotor. Under the electric regenerative effect, stator coil generates electric current that causes rotation of the rotor, balances the torque of counter-rotation of the sucker rod, what guarantees safe release of the torque.
4. Simple structure is convenient for maintenance.
