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： A hydrodynamic bearing unit is provided, by which the touch between oil and a sealing member in a housing is prevented to prevent oil leakage. A bearing member made of a sintered lubricant-containing metal is disposed along the inner periphery of the housing and a spindle is supported in a non-contact manner by the hydrodynamic oil pressure that is generated in a bearing gap by the rotation of the spindle. The opening of the housing is sealed by the sealing member. A ventilation path is formed so as to communicate a sealed space enclosed by the distal end of the spindle at the bottom of the housing, the bearing member and the housing with open air. An oil reservoir is formed between the inner periphery of the housing and the outer periphery of the bearing member at the end portion of the opening side of the housing. The oil reservoir is made so as to communicate with the ventilation path.
