The synchronous reluctance motor (SynRM) has many advantages over other ac motors. For example, its structure is simple and rugged. In addition, its rotor does not have any winding or magnetic material. Prior to twenty years ago, the SynRM was regarded as inferior to other types of ac motors due to its lower average torque and larger torque pulsation. Recently, many researchers have proposed se...

A series of synchronous reluctance motors (RSM) are analysed using finite element methods. The amount of iron in each rotor is kept the same. It is shown that the saliency ratio is not only dependent on the flux guide reluctance factor but also on the position or span of flux guides. It is also shown that an axially laminated design may not be an optimum configuration due to large number of flu...

The switched reluctance motors had gained more attention among the variable speed drives due to its inherent simplicity and low cost. It is an electronically commutated motor and need to be driven from a converter. The excitation of the different phases of the converter is dependent on the rotor position. This paper presents the simulation of the open loop control of a 6/4 switched reluctance m...

This document deals with solutions to control a switched reluctance motor using the TMS320C24x. This new DSP family enables cost-effective design of intelligent controllers for switched reluctance motors. Two speed control algorithms are presented, they allow the Switched Reluctance motor drive to reach high efficiency, smooth operation, very good dynamic behavior, very high speed and low acous...

Electrical motors drive a variety of loads in today’s world. Almost every industrial process relies on some kind of electrical motors and generators. There exist billions electric motors used in different applications all over the world. Majority of them are small fractional HP motors use in household appliances. However, they used about 5% of the electricity used by the motors. Three phase mot...

This paper presents a new model reference adaptive control method to control motor torque in direct drive reluctance motors in an accurate and ripple-free fashion. It is based on the motor's voltage equation and requires only measurements of motor angle, winding voltages and currents. In addition, we introduce a new optimal torque-to-current conversion which minimizes copper losses. Simulations...

This paper presents an adaptive neuro-fuzzy controller (ANFC) for the switched reluctance motors (SRM). The proposed controller is used for speed control of this type of motors. The dynamic response of the SRM with the proposed controller is studied during the starting process and under different disturbances. The effectiveness of the proposed ANFC is then compared with that of the conventional...
