This brushless motor consists of a squirrel-cage induction motor, a thyristor commutator and a speed detector. The driving control system has the constant slip, that is the ratio of the armature winding frequency to the secondary winding frequency. The thyristor commutator converts d-c into a-c such as the mechanical commutator of a d-c motor. Therefore, the steady-state torque vs. speed characteristics of this motor can be analyzed on the point of the d-c motor. The results are obtained that although this motor has the same characteristics as a conventional d-c series motor, it has the advantages that there is no mechanical commutator and the speed can be widely controlled. These show this brushless motor can be desirably used as a d-c motor.
