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.

摘要： A first comparison circuit compares the energization on angle outputted from a computer with the energization off angle outputted therefrom so as to output a first binary signal representing whether the latter is greater than the former. A second comparison circuit compares the energization on angle outputted from the computer with the rotation angle of the rotor outputted from the angle sensor so as to output a second binary signal representing whether the latter is greater than the former. A third comparison circuit compares the energization off angle outputted from the computer with the rotation angle of the rotor outputted from the angle sensor so as to output a third binary signal representing whether the latter is smaller than the former. A binary signal process circuit processes the first, second and third binary signals outputted from the first, second and third comparison means so as to output a fourth binary signal representing energization on and off.

摘要： A rising saw tooth signal generating circuit generates a rising saw tooth signal having a constant amplitude and a constant period which corresponds to a frequency being slightly higher than the human audible frequency range. The rising saw tooth signal generating circuit also generates a binary signal which generates a reference chopping timing synchronizing with the rising saw tooth signal. The rising saw tooth signal is inverted and a descending saw tooth signal is generated. The descending saw tooth signal is added to the reference current signal and a binary signal is generated by the result of the comparison between the addition signal and the actual current signal. A flip-flop generates a signal which reaches a low level whenever the binary signal is descended and which reaches a high level whenever the reference chopping timing comes. A further binary signal which moves to the high level at the feeding of the current and the signal are supplied to the AND gate. The output signal of the AND gate and the signal is supplied to an AND gate and a binary signal for driving a switching element is obtained.

摘要： The energization control system for a motor equalizes the power loss of switching elements energizing coils of each phase of the motor in order to maintain a balance of heat development. The energization control system for a motor includes a plurality of phase coils and two switching elements. The energization control system of a motor supplies an electric current from the power source line to the coil when two switching elements are simultaneously conducted. Two switching elements are controlled under a first condition that one of the switching elements is switched every predetermined time while the other of the switching elements is conducted. Two switching elements are also controlled under a second condition that the other of the switching elements is switched every predetermined time while one of the switching elements is conducted. The first condition and the second conditions are repeated and synchronized to the predetermined time every predetermined period.
