摘要： The current invention is directed to a high-speed optical deflector which includes a brushless motor operating in a high-temperature environment. The brushless motor components include rotatable parts made of various materials whose thermal expansion coefficients significantly vary. These rotational components include a steel rotor flange, a magnet rotor, and an aluminum shaft. To substantially eliminate rotational imbalance or vibration caused by the thermal expansion, the above described components are fixed with a certain adhesive which prevents these components from causing the rotational imbalance. A certain heat-resistant adhesive provides a sufficient structural strength to substantially minimize a rotational imbalance caused by the thermally expanding components in an operating temperature range.

摘要： In a brushless motor, the number of coreless armature coils is set to 3n when the number of magnetic poles of a magnet for a magnetic field is set to 2n where n is a positive integer. An opening angle of each of the armature coils is set to 360/3n degrees. A notch portion is formed in an outer circumferential portion of the magnet for a magnetic field. A recessed portion is formed by this notch portion and an inner circumferential portion of a yoke. The recessed portion constitutes a groove for correcting a balance of each of the magnet for a magnetic field and a rotating body when this magnet and the rotating body are rotated. A motor housing and a harness are electrically connected to a printed board. The housing is connected to the ground through this harness and a harness for power. In this brushless motor, a magnetizing frequency is reduced and driving efficiency of a control circuit can improved when the brushless motor is rotated at a high speed. Further, it is possible to prevent an iron or copper loss from being caused so that an increase in temperature of the brushless motor can be restrained.

The DC brushless motor switches conduction to windings wound around a stator core fixedly disposed corresponding to a rotatable rotor on which a permanent magnet is fixed, to generate a rotating magnetic field which causes the rotor to rotate. The DC brushless motor includes a permanent magnet having n magnetized poles, where n is an even number, a rotatably held rotor on which the permanent magnet is fixed, a stator core having T-shaped pole shoes corresponding to the magnetic poles of the permanent magnet, windings fixed on the stator core and including a plurality of phases for selectively generating magnetic polarities in sequence, a driver circuit for switching conduction to the windings, and a rotating position detector for detecting a rotating position of the permanent magnet. The windings are divided into a plurality of winding groups for generating magnetic polarities in a plurality of the windings so as to produce a magnetic repellent force or a magnetic attractive force between all the magnetic poles of the permanent magnet and T-shaped pole shoes of the stator core associated with selected phases by the driver circuit based on a rotating position detected by the rotating position detector.
