In the paper some results of design optimization calculations performed for induction motors with both the aluminum and copper cages, as well as for a line start permanent magnet synchronous motor (LSPMSM) with ratings PN=0.75kW, UN=400V, fN=50Hz, 2p=4 are presented. Basing upon obtained optimal designs, the prototypes of the LSPMSM and an induction motor with a reduced rated power PN=0.55kW have been manufactured. The experiments have proved that the LSPMSM has a selfstarting and sufficient overloading ability, and its rated efficiency (according to standards - direct efficiency determination by means of the torque meter test) is circa 89.1%. The properties of the optimized prototype of the induction motor could not be determined due to a delay in its correct manufacturing.
