Kind Code:
B2
Abstract:
The present invention provides a technique capable of realizing miniaturization of the axial size of a motor using a sensor. The motor of the present invention includes a rotor having a permanent magnet (56) and a stator (34) wound with a coil (60), and the motor further includes a sensor (42) for detecting a magnetic flux of the permanent magnet (56) to detect the rotor The rotational position ofthe sensor (42) is opposed to the axial end surface of the permanent magnet (56), and the sensor (42) is disposed radially inward of the coil end portion (60a) of the coil (60).
