Several embodiments of improved 2-phase DC brushless motors. In each embodiment, there are pluralities of windings and the current flow through the windings is controlled by a reduced number of main switches from the prior art type of devices. In accordance with a feature of certain embodiments, pair of windings are provided with a common CT that detects the current flowing through the connected pair of windings and which functions to control the main switching device in a pulse width modulated manner. As a result, the control circuit can be simplified and reduced in cost without sacrificing performance. <IMAGE> |
