Abstract: A rotating machine system includes a rotating machine including coils individually conducted in phases, respectively, an operation direction determination unit to determine an operation direction to a driving direction or a braking direction, a drive coil number determination unit to determine a number of coils in each phase based on a drive operation instruction value when the operation direction is the driving direction, a drive coil selector to select the coils of the number of coils determined from the coils in each phase, a drive controller to conduct the coils selected by the drive coil selector to perform drive control, and a brake controller to perform brake control based on a brake operation instruction value when the operation direction is the braking direction.

Abstract: There is provided a control apparatus that controls a motor of an electric power steering system to assist a steering effort of an operator. The control apparatus includes a sensor, a parameter computer, a difference computer, a target torque computer, and a motor driver. The parameter computer computes a current value of one of physical parameters of one of constituents of the electric power steering system based on a steering parameter determined by the sensor referring to an equation of motion. The difference computer computes a difference between the current value of the one of the physical parameters computed by the parameter computer and a predetermined value of the one of the physical parameters. The target torque computer computes a target torque of the motor which compensates for the difference between the current value and the predetermined value of the one of the physical parameters.

Abstract: A radial piston pump for the automotive brake system has a rotor, a couple of pistons reciprocated within a respective cylinder formed within the rotor and a bearing. The top end of the piston abuts directly to the inner surface so that no show is existed therebetween. The relationship within a starting point and a finishing point of a suction groove, a starting point and a finishing point of a disharge groove and an opening port the cylinder is designed in such a manner that at least one of a couple of cylinders connects to the suction groove during a whole rotation of the rotor.

Abstract: A radial plunger pump is provided which includes a motor housing having a motor mounted therein. A pump housing is further provided and has a pump portion defined therein. A shaft is mounted between the motor and the pump portion so that the pump portion operates when rotation of the motor is transmitted to the pump portion by rotation of the shaft. A constant pressure chamber is defined between a first seal member and a second seal member both of which are fixed to the pump housing. The leakage of oil from the pump housing toward the motor housing is prevented by the first and second seal members and the constant pressure chamber. Further, a plate is provided within the constant pressure chamber which rotates with the shaft and prevents the entry of foreign objects into the constant pressure chamber through a constant pressure port which communicates to the ambient atmosphere.
