Comparative Review of Brushless PMAC and PMDC Motor Drives

This paper presents a state of the art on brushless

Permanent Magnet Alternative Current (PMAC) and

Permanent Magnet Direct Current (PMDC) motor drives. The

brushless PMAC and PMDC motor drives are the latest choices

of researchers due to their high efficiency, silent operation,

compact size, high reliability, and low maintenance

requirements. These motors are preferred for numerous

applications. An in-depth analysis of PMAC and PMDC motor

drives have been discussed. The Permanent Magnets (PMs)

motor drives can be classified into two categories, first is PMAC

motor drives, i.e. PMSM and the second one is PMDC motor

drives, i.e. BLDC motors. There has been a long

misunderstanding between the two ways of driving and

controlling a motor with no windings on the rotor but only

PMs. In this paper given a comprehensive analysis of both

motor drives. So, beginner of the research scholars are easily

able to understand about brushless PMAC and PMDC motor

drives.
