<P>PROBLEM TO BE SOLVED: To provide a pole position detection device which costs lower than an existing pole position detection device, such as a resolver and an encoder, on a motor generator, without the need for changing the structure of a rundel type rotor or for increasing the size of the motor generator, by a large amount. <P>SOLUTION: The pole position detection device of the rundel type rotor is constituted by providing a magnet resin 19, constituting a detected body on the outer periphery of resin for molding a slip ring 10, and a semiconductor device 20 for detecting the pole position, such as Hall element or Hall IC is provided at a corresponding position. Accordingly, the pole position detection device can be provided easily on the motor generator 120 at a low cost, by only adding the magnet resin constituting a body to be detected and the semiconductor device for detecting the pole position 20 at the position, without changing the structure and design dimension of the motor generator 120. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
