摘要： An energization controller for an electric motor eliminates the possibility that a motor driver may be destroyed when the electric motor rotates in the opposite direction from its driving direction. The energization controller comprises energization circuits which are composed of an H type circuit together with an electric coil; a chopping control device for selectively performing a hard chopping mode of alternately repeating a switch-on operation of turning on both switching elements and a switch-off operation of turning off both the switching elements and a soft chopping mode of alternately repeating a switch-on operation of turning on both the switching elements and a singular-on operation of turning off one switching element and turning on the other switching element; a direction detection device for detecting a rotational direction of the motor; and a chopping mode control device for detecting whether or not the rotational direction coincides with a driving direction and for instructing the chopping control device to perform the hard chopping mode during when those directions do not coincide.

摘要： An overheating protection system for a switching module prevents thermal breakdown of switching devices for passing currents through a load, for example an electric motor, while making it possible for the switching module to provide as much required current to the load as possible. The system comprises a temperature detector for detecting the temperature of a switching module, a temperature estimator for calculating a temperature change rate of a switching device inside the switching module corresponding to a current passed through the load and calculating an estimated value of the internal temperature of the switching module on the basis of the calculated temperature change rate and the detected temperature and a current limiter for on the basis of the estimated value correcting a target current value of a current controller controlling a current passed by the switching device.

摘要： A piston, which reciprocates in a cylinder bore of an engine, is supplied with lubricating oil. The piston includes pin bosses provided under a piston head, a symmetrical pair of skirts, and side walls connecting the pin bosses and the skirts. The side walls have openings, which communicate the outer side of the walls with the inner side of the walls under the middle section of the head. A recess is defined in the lower surface of the head to receive a spray of lubricating oil. The width of the recess is wider than the width of each skirt at its basal portion. This causes the oil supplied to the lower surface of the head during movement of the piston to be injected against the recess and thus be diffused. As a result, oil passes by the basal section of the skirts and permeates into the space defined by the cylinder bore and the skirts.

摘要： The generation of oscillations and acoustic noises which result from a rapid change in the magnetic flux upon switching the energization is suppressed, while simultaneously preventing a reduction in the driving efficiency and preventing a resonance from occurring. The current waveform as the current rises or fails is switched in accordance with the rotational speed of the SR motor to minimize a change in the magnetic flux, thus suppressing a reduction in the driving torque. A time interval required for the current to rise or fall is chosen to be greater than one-half the period of the natural frequency of SR motor.

摘要： Suppression of a peak noise level as may be caused by a resonance when an SR motor is driven is intended. An offset is intentionally provided between a position for a maximum drive efficiency where the energization is to be switched and a position where the energization is actually switched. Such offsets s1, s2, s3, . . . are generated in terms of random numbers, producing a fluctuation in the frequency of the oscillations which result. The fluctuation in the frequency is effective to prevent the occurrence of a resonance. In order to avoid a resulting reduction in the drive efficiency, the magnitude of such offsets are limited to lie within a permissible shift angle, which is in turn determined in terms of the prevailing torque and number of revolutions, by reference to a map.
