The present invention relates to a plurality windings of U phase corresponding to one magnetic pole including first and second windings wound in a short pitch winding manner. The winding starts of the first and second windings are shifted by at least one tooth. The windings are wound so that a winding angle occupied by the windings inter-slot angle from the winding start of the first winding to the winding end of the second winding corresponds to a pole angle. The windings in the V phase are disposed in the same relationship as in the U phase at the position delayed by an electric angle of 120 degrees with respect to the U phase, and those in the W phase are disposed at the position delayed by an additional 120 degrees. The outputs of the windings are then each rectified, subsequently joined together and used by adding currents.

A motor includes: 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; and a choke coil connected in the middle of the power-feeding path. The choke coil 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.

A motor controller, including: a control box, a control circuit board, a first press strip, a control chip, and a plurality of plastic press blocks. The control box includes: an inner wall, a bottom, and a cavity formed by the inner wall and the bottom. The control circuit board is disposed on the bottom of the control box. The control chip is disposed on an outer edge of a top face of the control circuit board. The plastic press blocks are disposed in a middle of an end face of the first press strip. Two ends of the first press strip and the inner wall of the control box are assembled together. The control chip is pressed on the inner wall of the control box via the plastic press blocks.

Disclosed is a motor, the motor according to an exemplary embodiment of the present disclosure including a stator arranged at an inner surface of a housing and including a magnet, a rotor core centrally arranged at the stator to pass through a rotation shaft, a rotor including an insulator covering the rotor core and a coil wound on the insulator, a commutator coupled to the rotation shaft to be electrically connected to the coil, and a brush coupled to the housing to be closely contacted to the commutator, wherein the insulator is formed with a short-circuit prevention unit formed on a drop path of conductive particles in order to prevent the short-circuit between the rotor core and the commutator from being generated by the conductive particles generated by the commutator and the brush.

A scarecrow includes a scarecrow body corresponding generally in shape to a body of a live animal and an assembled hollow scarecrow head of molded plastic construction corresponding in shape to a head of the live animal. The assembled head includes a front face portion and a separate rear head portion fixed together to form the head, the front face portion having a front receiver and the rear head portion having a rear receiver. The scarecrow includes a motor having a rotatable motor shaft; a mounting insert fixed to the motor with the motor shaft extending below the mounting insert, the mounting insert received by the front receiver and the rear receiver to fix the mounting insert to the head; and a mounting bracket fixed to the scarecrow body and having a motor shaft receiver into which the rotatable motor shaft is received. Rotation of the motor shaft rotates the assembled scarecrow head relative to the scarecrow body.
