[M W Turner; V E McCormick; J G Cleland; National Risk Management Research Laboratory (U.S.)]. Jan 23,  · You can see that in both cases, the efficiencies of both types of motors drop. The NEMA Premium Motor efficiency drops from about 90% to about 72% at RPM and the ECPM drops from about 94% to 83%. While system operation affects equipment efficiency, permanent magnet motors have been proven to show higher efficiencies over AC Induction capitolchamberartists.com: Cieana Detloff.

    Base on the equivalent circuit of ship drive motor, the optimal running efficiency is deduced. With vector control technology the motor efficiency optimization control strategy and its application limit is given. Modeling in Saber, the paper compares efficiencies of efficiency optimization control with conventional vector control by simulation. Facilities with large motors may also locate capacitors at motors, helping reduce conductor and transformer current load up to the motor. The U.S. Energy Independence and Security Act (EISA) updated efficiency levels for 1-hp to hp motors. Power factor and motor efficiency.

    New hybrid model for efficiency optimization of induction motor drives (IMD) is presented in this paper. It combines two strategies for efficiency optimization: loss model control and search control. Search control technique is used in a steady state of drive and loss model during transient processes. As a result, power and energy losses are reduced, especially when load torque is significant Cited by: 2. An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor.
