    摘要： A polyphase sequentially joined-segment coil of a rotary electric machine and a production method thereof are provided. The coil is made up of a plurality of conductor segments joined in series. Each of the conductor segments a head projecting from a stator core, a pair of legs, and a pair of ends projecting from the stator core. The heads are of two types: a large-sized head and a small-sized head extending inside the large-sized head. This structure permits the length of the conductor segments in an axial direction of the core to be decreased and improves cooling capability of the machine and coil losses.

    摘要： A synchronous electric machine includes a stator having an armature winding, a rotor having axially laminated magnetic sheets and a field coil, a plurality of permanent magnets disposed in the rotor to form N-pole and S-pole on the outer circumference of the rotor, and ribs and pins magnetically bypassing the N-poles and S-poles of the permanent magnets. The pins also attach the laminated magnetic sheets together as a unit. The rotor has a plurality of axially extending holes on its circumference for accommodating permanent magnets.

    摘要： An anti-skid control system for use in a motor vehicle which includes a braking pressure adjusting device associated in common with at least first and second wheels of the motor vehicle to control braking pressures applied thereto. The anti-skid control system includes first and second wheel speed sensors for sensing rotational speeds of the first and second wheels, respectively, and a vehicle state detector for detecting a state of the motor vehicle such as a speed of the motor vehicle. Also included in the anti-skid control system is a control unit for controlling the braking pressure adjusting device on the basis of the sensed rotational speeds of the first and second wheels and the detected state of the motor vehicle. The control unit determines a weighting coefficient on the basis of the detected vehicle state and calculates a weighted average wheel speed on the basis of the determined weighting coefficient and the sensed rotational speeds. The control unit generates a control signal to the braking pressure adjusting device so that the braking pressure is controlled in accordance with the calculated weighted average wheel speed.
