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： A slot insulator is provided and includes: an annular part; and a plurality of insulated winding parts disposed a circumference of the annular part. Each of the insulated winding parts has an insulated winding holding part and an insertion groove for housing a winding part of a tooth in a stator yoke. The insertion groove opens in one direction along a center axis of the annular plate and opens at both ends of the insertion groove in a radial direction of the annular plate.

摘要： A variable-reluctance resolver includes a rotor and a stator. The rotor includes axially connected first and second rotor portions. The first rotor portion has n salient poles provided about a center axis at uniform angular intervals, where n is an arbitrary integer not less than 3. The second rotor portion has (n-1) salient poles provided about the center axis at uniform angular intervals. The stator has a plurality of magnetic poles provided on an inner circumferential surface thereof. An excitation coil and output coils for shaft angle multipliers of n× and (n-1)× are provided on the magnetic poles in order to output sine and cosine outputs having a phase difference of 90 degrees therebetween. A rotational angle sensor includes the VR resolver and a calculation section for calculating a resolver signal for a shaft angle multiplier of 1× from signals output from the VR resolver.
