This paper presents modeling and analysis of a hysteresis interior permanent magnet (IPM) motor drive for electric submersible pumps. A hysteresis IPM motor can self-start without the need of additional position sensors and complex control techniques. It does not have any slip power losses in the rotor at steady state which results in less heat dissipation and low electrical losses. When used in an...
Permanent magnet stepper motors are being applied as digital actuators for long time.

For a marine gas turbine generation set, the speed of power turbine must keep constant. Due to the varying load demand, the real and reactive power balance is damaged and thus the speed of power turbine becomes deviated from nominal value. It is necessary for an intelligent controller to keep the speed of power turbine within a permissible range during the varying load operation. The design of an...

The Single Phase Induction Motor (SPIM) is known for its simplicity and convenience. It is most commonly used in homes, businesses and small industries. One of the most known advantages of the SPIM is that they require a single phase to maintain the motor in motion. The only drawback is that due to the lack of starting torque, an additional auxiliary winding is required to start the motor. This increases...
