摘要： A pulse width of a drive pulse of a brushless motor is modulated in correspondence to a setting signal for setting the rotation rate. Switching control for the current supplied to exciting coils is implemented by using an output signal from Hall elements for detecting the position of the rotor and the drive pulse. Correction of the pulse width of the drive pulse is implemented to ensure that the average voltage is maintained at a constant level even when the source voltage fluctuates so that stable rotation can be maintained over the entire rotation rate range even when the source voltage supplied to the brushless motor fluctuates and so that the fuse can be prevented from melting and the motor can be prevented from becoming damaged, which may otherwise be caused by a fluctuating source voltage.

摘要： An object of preventing a reduction in the output efficiency of a motor in the high speed rotation range and reducing the noise of the motor in the low speed rotation range is to be achieved. Since, if a signal that corresponds to the rotation rate has a value equal to or smaller than a specific value, the timing with which a switch performs switching is retarded relative to the timing used when the signal corresponding to the rotation rate has a value larger than the specific value, once the operation shifts to the low speed rotation range, the switching timing is retarded to shift from the setting that gives priority to efficiency, to the setting for achieving noise reduction as long as the switching timing is set in advance so that an optimal output efficiency is achieved in the high speed rotation range.

摘要： In order to prevent the performance of a motor from deteriorating due to a change in which the rotation rate of its rotor is to be increased suddenly, in a brushless motor in which a drive pulse whose pulse width is modulated in correspondence to a rotation rate setting signal input from the outside is formed and switching control is performed on the current supplied to the exciting coils by using output signals from the Hall elements that detect the position of the rotor and the drive pulse, the pulse width of the drive pulse is changed gradually and greatly until it reaches the pulse width that corresponds to the rotation rate setting signal when the upward change in the rotation rate of the rotor is to be large.

摘要： In order to protect a brushless motor, heat generated at a switching device, in response to an abnormality, activates a protection device. The protection device includes a connecting line communicating between a source supply line and the switching device. The protection device is provided near the switching device such that it can sense heat at the switching device with a high degree of sensitivity. Thus, when excessive heat is generated at the switching device, the protection device reaches a specific temperature, whereby the source supply line becomes cut off from the switching device, thereby immediately stopping the operation of the brushless motor.

摘要： The present invention offers a simple structure that facilitates the mounting of bearings, that maintains lubricating oil at a sufficient level in the bearing portions and that maintains an optimal distance between a rotor and a case housing for preventing freezing, for preventing reduction of the capacity and for preventing noise. Bearing stoppers provided between the bearings of the brushless motor and the bearing holders, which hold the upper end edge of each bearing, are secured at a projection formed at the internal circumferential surface of each bearing holder. A felt, which comes in contact with the lower portion of each bearing stopper and also comes in contact with the bearing at one side is provided, with holes communicating with the felt formed at the lower surface of the bearing stopper. In addition, the lower limit of the distance h between the lower end of the rotor and the upper end surface of the case housing is set at 1.5 mm. This prevents water from forming a connection between the rotor and the case housing due to capillary action and surface tension. In addition, the upper limit of the distance h is set at or under 8 mm, which represents the critical point for the capacity and the noise. This ensures that the capacity is maintained at a satisfactory level and also prevents noise from increasing. Moreover, a washer group, which comprises at least one each of a resin washer, a rubber washer and a POM (polyoxymethylene) washer is provided between a sensor magnet that is secured to the lower end of the rotating shaft and the lower bearing.

摘要： A stepping motor control device for an automobile air-conditioning system has a key-off home-position setting unit of a stepping motor for driving an air-conditioning door in response to switching of a key switch of the automobile off. The key-off home-position setting unit, responsive to switch of the key switch off, drives the stepping motor so that the air-conditioning door comes to a full-close position or a full-open position, stores data indicative of the full-close or full-open positions, as a current position of the air-conditioning door in a memory, and thereby finishes a home-position setting of the stepping motor. The key-off home-position setting unit is supplied with power from a power source under control of a timer for a prescribed time within which a home-position setting can be finished. When the key switch is turned on, the key-on control unit judges whether or not a current position of the air-conditioning door given by the key-off home-position setting unit is stored in the memory, and starts a normal air-conditioning control without performing a home-position setting if the current position is stored.

摘要： A pulse motor control device comprises, as additional component parts, a power-off detecting circuit, and a turning-off circuit. The power-off detecting circuit detects, when a driving switch is turned off, a dropping of a voltage supplied to a driving circuit and outputs a power-off detection signal. The turning-off circuit includes diodes and a control resistor. The diodes are connected respectively to control terminals of all driving transistors of the driving circuit. When the control transistor is turned on in response to the power-off detection signal, voltages of control terminals of the driving transistors are dropped to the ground level through the diodes, thereby turning off the driving transistors.
