Motor

A motor comprising:

• an end bell mounted on an opening of a cylindrical rotor housing for housing a rotor and is provided with a power-feeding path to the rotor;
• a noise prevention element connected in the middle of the power-feeding path;
• a first circuit substrate used for a rotation detector for detecting rotation of the rotor;
• and
• a second circuit substrate separate from the first circuit substrate and used for the noise prevention element, wherein
• the noise prevention element overlaps at least a part of the rotor housing as viewed from outside the rotor housing in a radial direction and as viewed in a direction perpendicular to an axial direction, and is arranged such that a longitudinal direction thereof extends along a direction parallel to a rotating shaft of the motor,
• the first circuit substrate is provided inside the rotor housing in the radial direction, and
• the second circuit substrate is provided outside the rotor housing in the radial direction.
