The induction machines are suitable for operation through the inverter transducers, because the winding insulation of standard induction motors tolerates certain voltage overload but at higher speeds of rotation, that is, higher frequencies; they have higher noise level and additional losses [2-4], which affect the motor output torque, depending on the regulation range of the speed of rotation and power factor correction [5-9].
Industrial conveying and handling machines typically use expensive permanent magnet synchronous drives ("servo") or cheaper induction motors equipped with brakes and clutches.
Induction motors connected across the line at start draw large currents, approximately 600 percent of rated current, and this current remains high through most of the start.
Fast, dependable, easy to use, and easy to integrate and install, the inverter can be used in induction motors and next-generation interior permanent motors.
Unfortunately they are also expensive, which explains the greater purchase price of PMSMs compared to induction motors.
Asynchronous machines, which contain asynchronous induction motors and induction generators, are important equipment in power systems.
The topics include control models for synchronous machines, high-gain observers in the robust feedback control of induction motors, the experimental evaluation of nonlinear control design techniques for sensorless induction motors, the adaptive output-feedback control of permanent-magnet synchronous motors, the nonlinear state-feedback control of three-phase wound rotor synchronous motors, and applying induction motor control in high-speed train electric drives.

The motors are being developed as part of a research project to increase the efficiency of induction motors. The aim is to challenge perceived limitations that hamper market acceptance of electric cars: short range and high purchase price.
Induction Motors (IM) are used in many industrial applications because they are characterised by high reliability, low cost per power unit, high power per volume unit and need very low maintenance.
Also available in 3hp and 5hp 1,800 rpm (maximum speed 2,700 rpm), these motors use low-cost ferrite magnets in a flux-focusing design to deliver the efficiency of rare-earth permanent magnet motors at a price competitive with induction motors. Driven by variable frequency drives, these units feature motor-only rated point efficiencies of 93% and 92% for 3-hp and 5-hp versions respectively.
Digital motors offer a great many advantages over standard induction motors and are designed to cope with frequent starts and stops.
