摘要： A wind driven electrical power generating apparatus includes a rotor rotating by receiving wind force, a gear assembly having an input shaft connected to the rotor, a generator connected to an output shaft of the gear assembly, a sensor for detecting generating capacity of the generator and a controller for varying gear ratio of the gear assembly based on a signal from the sensor. In this construction, the controller controls so that the generator keeps rotating at around the lowest rotational speed within a range of rotational speed, the range being determined so as to include a maximum power operation region of the generator. Alternatively, the controller controls so that rotational speed of the output shaft of the gear assembly is adjusted to at around the lowest rotational speed within a range of rotational speed, the range being determined so as to include a rated power region as an upper operational limit.

摘要： A wheel bearing assembly for transmitting an automotive drive force from an electrically operated drive motor (1) to a wheel (52) is designed to have a compact and lightweight structure and to enable standardization of assemblage of electric motorcars. The wheel bearing assembly includes an outer member (41) formed integrally with a radially outwardly extending flange (44) for securement of the assembly to an automotive fame structure, and an inner member (42) having a center bore (49) and adapted to be driven by the drive motor 1 through an axle (60) fixedly inserted into the center bore (49). Each of the inner and outer members (41) and (42) has two raceways with respective rows of rolling elements (43) intervening therebetween. The inner member (42) has a radially outwardly extending wheel mounting flange (42) to which the wheel (52) is secured.
