Abstract :
The brushless dc motor described in this article is composed of six thyristors and of a single synchronous motor with an auxiliary position sensor. On the field poles of this motor compensating windings are provided. These windings are connected in series with dc supply as is the case with a dc motor. However, in the motor described in this article the commutation is performed by the armature induced voltage, therefore commutating devices such as capacitors, reactors and auxiliary thyristors are not required.
