发明名称 MOTOR, MOTOR DEVICE AND POINTER TYPE DISPLAY DEVICE
摘要 <p>PROBLEM TO BE SOLVED: To provide a motor capable of suppressing oscillation of a rotor toward a radial direction, as well as a motor device and a pointer type display device having the motor.SOLUTION: In a motor 1, coils 9 are arranged around each of two salient poles 61f, 61b (main poles) located in a first angular rangeθ1 of less than 180 degrees, out of a plurality of salient poles 61 of a stator core 60. Salient poles 61c-61e located in a second angular rangeθ2 of 180 degrees centered on an extended line Lb of a virtual bisector La that bisects the first angular rangeθ1 on a side opposite to a side where the two main poles (salient poles 61f, 61b) are located, out of the plurality of the salient poles 61, are first interpoles around which coils 9 are not arranged. A first interval g1 between the main poles (salient poles 61f, 61b) and a magnet 50 is smaller than a second interval g2 between the first interpoles (salient poles 61c-61e) and the magnet 50.</p>
