PROBLEM TO BE SOLVED: To reduce influence of a leakage flux from a shaft affecting sensing of a rotation sensor in a rotor field electric motor.SOLUTION: A sleeve 24 is disposed at a tip part of a shaft 3 to shield a leakage flux B flowing from a field magnet 9 to the shaft 3. A sensor target 22 is fixed at the tip part of the shaft 3 while interposing the sleeve 24 therebetween. |
