Abstract
PURPOSE: To prevent an AC motor from damaging by detecting the switching time point of a torque polarity, and operating it so that a torque current component is zero, i.e., only with a magnetizing current component for a predetermined time from this time point to suppress the rise of a motor voltage.
CONSTITUTION: A controller 16 presumes a load torque, takes a difference between the presumed value and a load torque corresponding amount iT, compares the difference with a predetermined value to detect a switching time point from a driving mode to a control mode. and outputs a signal which becomes 'H' for a predetermined period from the detection time point. Thus, since the output of ASR 6 is held at zero (iT=0) only during this period, a motor current is only iM during this period (specified exciting current value), and even if a motor power factor becomes zero, the motor voltage does not exceed.
