In the paper, the results of laboratory tests of a surface mounted permanent magnet brushless motor were presented. Two power electronics systems, which are made as inverters for PMSM and BLDC motors, were used. The PMSM inverter supplies the motor with sinusoidal currents and the BLDC inverter supplies the motor with trapezoidal voltage. The motor characteristics and its waveforms were determined when the motor was supplied from the BLDC inverter and the PMSM inverter. A comparison of the influence of the motor supply method on its features and parameters was performed.
