Abstract

An analysis of permanent-magnet DC brushless motors supplied by current control inverters is developed, using a finite-element package tailored for such devices. The study is devoted to predicting the performance of a set of four-pole machines under different operating conditions (no load, rated load). Overload conditions, including the saturation effect, are also considered. The influence of such design parameters as the tooth shape and the number of magnet segments is investigated. Computed results are found to be in satisfactory agreement with experimental ones
