This paper investigates the design, manufacturing and comparison of low voltage 33-slot permanent magnet AC motor with symmetric and asymmetric winding. Design and analysis of the motors are performed to get information about performance characteristic of both motors for a set of given specs. No-load and on-load analyses are accomplished in order to obtain voltage and torque constants. Prototype motors are built with two sets of AC windings. Motor performances are verified experimentally and the analyses are compared with the design data. Good agreement between the designed motors and the test results is observed for this low voltage high current application.
