摘要： A motor driving apparatus has a loss-of-synchronism monitoring circuit that monitors the rotation of a rotary machine such as a brushless DC motor to detect a sign of transition to a state of loss of synchronism. When the sign is detected, an energization control circuit temporarily stops driving of the rotary machine to bring it into a free running state, and thereafter carries out control so as to resume driving of the rotary machine. Further, the motor driving apparatus has an inverter and a drive control circuit that controls switching operation of the inverter based on rotation of the rotary machine.

摘要： An apparatus for estimating rotor position for brushless motors capable of accurately estimating rotor position even though power source voltage fluctuates is provided. First, the power source voltage is detected, and voltage is supplied only for a certain period of time and a current response is detected. The current detection value is multiplied by the ratio of a reference voltage to the power source voltage detected to correct the current detection value. Specifically, the peak current detection value is corrected upwardly or downwardly in each direction. A voltage supplying direction in which the current detection value is maximized is searched for to estimate the rotor position and a brushless motor is started.

摘要： A stator core of a motor arrangement includes six cores, which are arranged one after another in a circumferential direction. A bobbin, which is made of dielectric resin, is fitted to each core. Each coil is formed such that a winding is wound around the bobbin through a concentrated winding technique. Dielectric resin is filled between each circumferentially adjacent two teeth to cover each coil. Furthermore, the dielectric resin is molded to form clearances, each of which is formed between the corresponding circumferentially adjacent two teeth on a rotor side. Fuel, which is pressurized by a pump arrangement, passes an interior of the motor arrangement through a fuel passage, which is a gap between an inner peripheral surface of the stator core and an outer peripheral surface of the rotor, and also through the clearances.
