| titleOfInvention | Electromagnetic finite rotation type motor |
| abstract | (57) [Abstract] [Purpose] To propose an electromagnetic finite rotation type motor equipped with a detector capable of detecting with high accuracy the information related to the rotation of the rotating shaft necessary for controlling the rotation with high accuracy. A position detector 100 for detecting a rotational position and a speed of the rotary shaft 2 is provided at a front end portion and a rear end portion of the rotary shaft 2 of the electromagnetic finite rotation type electric motor 1, respectively. And the rotational speed detector 10 is incorporated. The detector 10 includes a rotor having a structure in which a ring-shaped permanent magnet 11 magnetized with two poles is attached to the outer circumference of a rotating shaft 2, first and second yoke pieces 14 and 15 enclosing the outer circumference, and inside the rotor. It is composed of a stator composed of the mounted ring-shaped field winding assembly 16. Field winding assembly 16 Based on the rate of change of the magnetic flux interlinking with, the rotation speed of the rotating shaft 2 rotating at a finite angle can be detected. In addition, the position detector 100 Is an optical potentiometer, the rotary slit plate 101 thereof has a pair of fan-shaped portions, and spiral slits having different pitches are formed in each fan-shaped portion. |
