Abstract: PURPOSE:To miniaturize it without enlarging the capacity of a power converter more than necessary by providing a means which controls the phase of an armature current so that it compensates the change of voltage by the reaction of the armature, monitoring the voltage of a synchronous motor. CONSTITUTION:When a current command 1m is given, an armature current of the magnitude in accordance with the current command Im flows as a sine wave current synchronized with the rotational angle thetav of the rotor of a synchronous motor, and the rotor generates specified torque and rotates. When motor torque and load torque balance and it gets in the condition of rotating at constant speed, the inner induction voltage E0 of the armature is established, and the terminals voltage V1 in accord with the reactance voltage Vx by the armature current Ia is established. A compensating signal theta which is output from a voltage compensating part 1 according to the deviation between this detection voltage V1 and voltage command V1, is added to the rotational angle thetav, and the phase of the armature current Ia is controlled so that the voltage deviation may be zero, and the reactive current changes.

Abstract: PURPOSE:To eliminate a necessity to always pay attention to the use cumulative time of the title device device and to always maintain the performance of the device by accumulating recoding or reproducing operation time, giving an alarm to a handler and informing him when the cumulative time becomes a fixed time or above. CONSTITUTION:A recording or reproducing operation deciding circuit 1 decides whether the device is operating or not and when it is operating, an operating time adding circuit 2 measures an operating cumulative time T.

Next, it is checked at any time whether or not the operating cumulative time T added by the operating time adding circuit 2 is larger than a time T1 set beforehand. When the operating cumulative time T becomes the set time T1 in a time comparing circuit 4, a display part 5 displays the characters of cleaning and urges the handler to clean a magnetic head. Thus, it is unnecessary to always pay attention to the use time of the device and the performance of the device can be always maintained.
