Permanent Magnet Synhronous Motor and Universal Motor comparison for washing machine application

Efficiency is one of the most important characteristics of home appliances since there are tremendous amounts of units out in the market. Main factor effecting the efficiency of these home appliances is the efficiencies of the electrical motors used in them. A comparison is made for two particular motors used in washing machine; a Permanent Magnet Synchronous Motor and a Universal Motor. Comparison is made on the basis of efficiency, torque, speed capability, current and induced voltage. Results are also presented and compared with the experimental results.
