摘要： Angle bounds of a normal energization of the coil of an electric motor are generated in accordance with a combination of a rotation direction and a torque direction of the electric motor. Angle bounds of the decided energization are determined based on a decision of either energization or deenergization of the coil and the detected rotation angle of the rotor. An abnormal condition is determined to exist when the angle bounds of the decided energization are not within the angle bounds of the normal energization.

摘要： For detecting a coil short-circuit in an electric motor such as a switched reluctance motor, an apparatus includes a first phase coil, a second phase coil, and a third phase coil. Through each of the coils, a current, whose amount is sensed by a current sensor, flows in such manner that the amount ranges from zero to a reference current amount in a reference set-up time duration. If the detected amount of current by the current sensor becomes the reference current amount in a time duration which is shorter than the reference set-up time duration and the resultant condition continues for an another reference time duration, it is regarded that a short-circuit occurs in the phase coil corresponding to the current sensor and the apparatus stops the electric motor.

摘要： An energization control device is provided to prevent rapid decrease of current which is flowing through each of phase coils of an electric motor. A time duration is divided into three stages which ranges from an initiation of the current supply to the phase coil to a termination of the current supply to the phase coil. At the first stage, the second stage, and the third stage, soft/hard chopping energization control, 0-volt energization, and duty chopping energization control, respectively, are made. Energizing the phase coil is made by way of a first switching element and a second switching element. At the first stage, depending on an actual current value being in excess of a target current value, either of or both of the first switching element and the second element are made OFF. At the second stage, while the second switching element is being made OFF, the second switching element is made ON. At third stage, while the second switching element is being made OFF, the first switching element is, at a duty cycle, made ON and OFF alternately in repetition.
