Abstract
PURPOSE:To prevent the variation in the motor characteristics due to the difference of power frequency by discriminating the power frequency and cntrolling the phase of a switching element is response to the discriminated result. CONSTITUTION:This device has a phase controller 1, a power frequency discriminator 5, a discriminator 4 receiving the outputs of the controller and the discriminator, a motor drive unit 6 receiving the output of the discriminator 4 as an input, and a motor 7 controlled by this drive unit 6. In case of 60Hz, the output of the discriminator 4 allows the synthesize 2 to produce its output as it is to control the phase of a bidirectional switching element 26, and in case of 50Hz, a constant output is delivered to control the switching element 26 is full conduction. Thus, even in both 50 and 60Hz of power frequency, the motor perform the same characteristics, thereby eliminating the conventional pully exchange.
