摘要： Small brushless motor having high output and small torque ripple. The brushless motor includes induction voltage adjusting means. With this, induction voltage of each phase of the stator is adjusted into a flatly spread waveform having no abrupt variation where odd-numbered of order harmonic is superposed, thereby obtaining a small motor having high output capable of efficiently generating large torque with small ripple.

摘要： A technique and structure for establishing a sufficient electrical connection between an armature and a power supply of a motor even for use in severe working environments through at least one busbar is such that each of the at least one busbar is connected a conductor wire arranged to supply a drive current to the armature of the motor. The structure includes a terminal plate having a through hole defined therein to allow the conductor wire to pass therethrough, and a terminal wall arranged to rise above the terminal plate from a periphery of the through hole.

摘要： In an armature for a brushless motor, a gap is provided between an inner circumferential surface of a cylinder portion of a cover and an outer circumferential surface in a radial direction of the armature. A plurality of non-magnetic spacers having a predetermined distance therebetween are provided in a circumferential direction so as to make contact with the inner circumferential surface of the cylinder portion and the outer circumferential surface of the armature.

摘要： Motor having small torque ripple. In a core of an armature of a motor, teeth are disposed radially around a center axis, arrangement of pitch angles of the teeth having different picth angles, or arrangement of tip end widths of the teeth having different tip end widths is repeated three or more times in the circumferential direction, the number of teeth is greater than the number of poles of the field magnet and with this structure, the tip ends of the teeth are varied, and with this effect also, the torque ripple is reduced.

摘要： In a motor, an sensor magnet is attached to a shaft and three hole sensors for detecting the position of the sensor magnet are mounted on a circuit board. By using neodymium-iron-boron base rare earth magnet having radial anisotropy as a sensor magnet, the detection accuracy for the position of a field magnet via the sensor magnet by the hole sensor can be improved.
