ON THE ANALYSIS OF SPHERICAL MOTOR

Abstract

The principle of spherical motor was first published in the year 1955. After several abortive attempts, the motor was successfully fibricated and its design details were reported in 1959. The most peculiar feature of this motor is that an angle 8 can be introduced between the direction of motion of rotor and direction of motion of the stator field (which are parallel to each other in conventional squirrel cage induction motor). This dissertation work deals with the analysis of this motor. Review of the past work is divided into two chapters, II and III. Chapter II describes complete review while III elaborates the analysis for the specific case of B = 00. Chapter IV deals with generalisation of the analysis described in chapter III, for any value of 9. Expression for power output is obtained in terms of 0, which gives satisfactory results in the full range of 8 (which is 00 to 900) for a simplified model of the machine. Construction of a present-day spherical motor is briefly described in Appendix.
