摘要： Reinforcing body retainers are formed on an inner peripheral surface near a tip and near a root of first and second claw-shaped magnetic poles. Reinforcing bodies have a trapezoidal base portion and a pair of wing portions formed on two sides of the base portion, and slits are formed completely across a width direction of the base portion at a central portion in a height direction of the trapezoidal shape of the base portion so as to be offset toward a base of the trapezoidal shape. The reinforcing bodies are disposed so as to contact the inner peripheral surfaces of the first and second claw-shaped magnetic poles with a magnet housed and supported in each of the wing portions, and a D ring is fitted into the slits of the reinforcing bodies.

摘要： A motor controller is provided which can be reduced in the number of the wirings and power semiconductor devices required while maintaining the function equivalent to or higher than that of the motor controller adopting the existing winding changeover scheme, thereby realizing cost and size reduction and life increase. The motor is made in a structure having motor windings opened at both ends. The one end terminals of phase windings are respectively connected to the output terminals of a first inverter circuit while the other end terminals are respectively connected to the output terminals of a second inverter circuit. During power generation, any one of the inverter circuits is driven on all the phases by means of a same control pulse.
