Description
Summary:An optimal design of internal Ferrite permanent magnet motor with embedded key FEM verification is presented with the scope to increase the efficiency of the small power motors without to use the expensive, rare earth permanent magnets. Two internal flux concentration topologies are analyzed and the geometric dimensions and performances are presented for three cases, all at 1kW rated power at 4500rpm rated speed. The 6/8 poles spoke PMSM prototype was build and test results prove an efficiency larger than 88% for a large load range. Two sensorless control methods based on active flux observer are presented with the key simulation results including acceleration, speed reversal, loading and unloading speed response.
