Project 2

Synchronous Motor design create on RMxprt is export in Maxwell 2D.

This software is used to create meshing for FEA [2].
Electromagnetic analysis is done with the help of Maxwell
2D.Motor in Maxwell 2D is shown in fig.1

Fig.1. motor in Maxwell 2D

There are some analysis are done on the basis of simulation
in Maxwell 2D .Fig.2 shows the mesh formation at specific
time of rotor position.

CONCLUSION

In this paper Permanent Synchronous
motor used in solar vehicle of 10kW and 3000 rpm is
design. This paper shows that motor gives considerably good
efficiency at rated torque and at rated speed.Motor is design
in RMxprt and the its electromagnetic field analysis is done
on Maxwell 2D. After designing of motor, analysis is done
by varying the lead angle of control circuit. It is seen that
when the lead angle is increased from 0 degree to 30 degree
efficiency of the Permanent Synchronous Motor is increased. By
increasing lead angle rated speed of motor is increased.
Increase in efficiency is achieved at the cost of decrease in
rated torque and increase in ripple in torque.
