PURPOSE: To easily perform build-in operation by separately providing a timing pulley which is different from the timing pulley provided at the opposite output side of a rotor at a corresponding position and connecting each timing pulley with a belt for detecting a rotary position. CONSTITUTION: A motor body is constituted of a stator 1, a rotor 2, casings 3 and 4, and bearings 5 and 6 and connected to a timing pulley 11 of a rotary shaft 10 of a rotary detector 9 by a timing pulley 7 and a timing belt 8, thus rotating a rotary detector 9 in synchronization. By separating the rotary detector 9 from a motor drive shaft, the type and size of the rotary detector 9 can be selected regardless of the size of the motor and at the same time the frequency of a detection signal can be changed by changing the pulley size. Also, direct application of load fluctuation to the rotary shaft and vibration and shock to shafts for the rotary detector can be reduced, thus reducing possible inconveniences. |
