The permanent magnet motor family is an innovative approach to saving electricity. The motors are characterized by:

  • Higher efficiency,
  • Higher power factor, even with less motor load,
  • Maintaining high efficiency and power factor values over a wide load range,
  • Possibility of obtaining more power in smaller dimensions,
  • Direct start – no frequency converter required.
The advantages of permanent magnet motors are most visible in installations where drives operate almost continuously: pumps, fans.
A conceptual comparison of the efficiency and power factor as a function of load is shown in the charts below.
