摘要： A VR resolver includes a stator yoke having a plurality of magnetic-pole portions; a rotor having a salient-pole portion; an excitation coil; and a plurality of output coils. The stator yoke and the rotor form an annular, hollow structure having a rectangular radial cross section. The excitation coil is provided in the hollow portion of the annular, hollow structure. The output coils are provided at the corresponding magnetic-pole portions of the stator yoke.

摘要： A variable reluctance resolver has a rotor which includes a noncircular core and which is rotatably supported inside a stator with a gap therebetween. The shape of the rotor is such that the gap permeance, which is based on the gap, varies according to a sine function of the rotational angle. Each of the salient poles of the rotor has an outer periphery comprising an arc of radius r centered on a point which is offset from the center of the rotor by a prescribed offset distance. The outer periphery of each salient pole does not extend to the inner periphery of the stator.

摘要： An electromagnetic clutch comprises a rotor rotatable with respect to the center of rotation, an armature facing the rotor with a clearance, a device for generating a magnetic attracting force between the rotor and the armature, a rotating member transmitting a driving force from the armature, and a plate spring for mounting the armature on the rotating member. The plate spring extends in a direction opposite to the center of rotation and has a first end separated from the center of rotation. The first end or a portion in the vicinity of the first end contacts an armature surface facing the rotor, and the plate spring is fixed to the rotating member at a portion other than the portion contacting the armature surface. The armature is supported such that the armature is urged to be separated in a direction opposite to the rotor by an elasticity of the plate spring.

摘要： A stator core 1 is surrounded by a first insulating member 40 and a second insulating member 41. Locking protrusions 9 are formed on the outer periphery of the stator core 1, and the locking protrusions 9 form a keyway 11. A modular connector 2 includes a key part 21 that fits within the keyway 11 to secure the modular connector 2 to the stator core 1. Fastening pins 18 are embedded in the modular connector 2 to conduct electricity from a mating connector 91 and a lead line 93 to the resolver.
