摘要： The electric fan assembly includes an electric motor composed of a rotor (11) having a fan wheel (12), and a stator (10) fitted with a card (50) supporting a printed circuit for determining operation of the motor. The stator includes a bearing (60) having two main opposite faces, a lower face and an upper face, for mounting the stator (10), defines a seat (62) for the assembly formed by the card (50) and a plurality of MOSs (54) projecting from the edges of the card, where the MOSs are coplanar to the card. The seat (62) has a depth dimensioned to receive a layer of solidifying resin covering and protecting the printed circuit and the relevant connections. The stator bearing (60) is axially crossed by channels (65) providing electric connection between the stator winding leads (30) and electric contacts (52) located on the card (50) proximate to an opening (51) obtained in the card at the channels (65). Axial fins (31) extend from the upper face of the stator bearing (60) for engaging the stator (10) axially and radially.

摘要： The circuit comprises synchronisation devices operable to provide, for a motor having n phases, n square wave control signals phase displaced from one another by 360/n electrical degrees, with a frequency proportional to the speed of the rotor of the motor, and linear feedback pilot circuit devices operable to provide at their output, cyclically to each of the power transistors, which pilot the phases, a respective pilot signal variable as a function of a reference signal and the voltage on the corresponding phases of the motor.

摘要： A keyboard unit is shown having a substrate in which portions of the substrate are physically displaced to provide a cavity, an embossment and a plurality of protuberances for each switching station. The embossment, in registry with a button contact area, projects upwardly from the floor of the cavity a selected distance with a discontinuance annulus contact area extending around its respective cavity in generally the same plane as that in which the top surface of the substrate lies. The cavity includes a channel shaped portion extending through the discontinued portion of the discontinuous annulus. The protuberances project upwardly from the general plane of the substrate's top surface and serve to laterally locate a snap-acting disc over the contact areas. The disc may be selectively coated with highly electrically conductive material to optimize electrical switching. A piece of flexible, electrically insulative sheet may be placed over the unit to seal it from the environment.
