In the present study, a prototype of coreless PMDC motor was successfully developed, tested for its performance characteristics and analyzed for its performance comparison with a cored PMDC motor of the same power rating. The comparative performance analysis showed that the coreless PMDC motor has a wider torque and speed range as compared to cored PMDC motor for the same input current range. The rotor speed range in coreless PMDC motor was found lesser than that of the cored PMDC motor for the same Voltage range. The slope of Torque vs rotor speed graph for coreless PMDC motor was significantly lesser as compared to that of cored PMDC motor. Also the torque level was much higher for coreless PMDC motor in comparison with that of cored PMDC motor. The cost analysis of the prototype showed that the manufacturing cost is significantly competitive since the laminated steel core is absent in the coreless PMDC motor.

Abstract


In the present study, a prototype of coreless PMDC motor was successfully developed, tested for its performance characteristics and analyzed for its performance comparison with a cored PMDC motor of the same power rating. The comparative performance analysis showed that the coreless PMDC motor has a wider torque and speed range as compared to cored PMDC motor for the same input current range. The rotor speed range in coreless PMDC motor was found lesser than that of the cored PMDC motor for the same Voltage range. The slope of Torque vs rotor speed graph for coreless PMDC motor was significantly lesser as compared to that of cored PMDC motor. Also the torque level was much higher for coreless PMDC motor in comparison with that of cored PMDC motor. The cost analysis of the prototype showed that the manufacturing cost is significantly competitive since the laminated steel core is absent in the coreless PMDC motor.
