PROBLEM TO BE SOLVED: To avoid a positional shift between a rotor core and a sensor rotor, which is produced by an excessive inertia force applied to a rotor. SOLUTION: This motor with a pole position sensor has a motor rotor A, which has a laminated core 1 and end plates 2A and 2B attached to both the ends of the laminated core and a pole position sensor 4 for detecting the pole position of the motor rotor. The sensor rotor 41 of the pole position sensor is fixed to the end plate 2A of the motor rotor, so as not to rotate. With such a constitution, the sensor rotor can be connected directly with the motor rotor, without having to use additional elements and the positional shift between the motor rotor and the sensor rotor can be avoided, so that the pole position of the motor rotor can be detected with high accuracy by the pole position sensor. |
