synchronous reluctance motor construction and working pdf

Institute Technology DC” MIT OpenCourseWare. Synchronous reluctance. synchronous reluctance motors (synrm) have an equal number of stator and rotor poles. the projections on the rotor are arranged to introduce internal flux “barriers“, holes which direct the magnetic flux along the so-called direct axis., a variable reluctance motor intended to move in discrete steps, stop, and start is a variable reluctance stepper motor, covered in another section. if smooth rotation is the goal, there is an electronic driven version of the switched reluctance motor. variable reluctance motors or steppers actually use rotors like those in figure.

Advantages of Synchronous Reluctance Motors. Motors is the higher initial cost of installation of direct linear motor drives as compared to traditional mechanical drives. the north american market for linear motors totaled only us$ 40 million, synchronous motor is constant speed motor irrespective of the load so such kind of motors are used where constant speed is required like heavy industry. in synchronous motor speed is depend only on the supply frequency and such motors are very attractive for low speed drives because the power factor can be adjusted to 1 and the efficiency is high..
