Title: Improvements in the cooling of motors driving extraction fans
Inventor: AVRIL PIERRE
IPC: F04D25/08
Filed: 1983-03-17
Abstract: The cooling of a driving motor (2) of a turbine (1) which is used as an extraction fan for evacuating heated fumes or smoke from an enclosed area, is provided by a frusto-conically shaped hood (7) which is supported on a plate (3) by means of an annular cage (8) carrying a grid (9). The lower peripheral section of the hood (7) together with an annular downwardly inclined extension (14) of the support plate provide a throttle which together with the flow of heated fumes or smoke through an annular cage (14) from the turbine (1) cause a venturi effect to occur, the resulting drop in pressure at the throttle causing the flow of cooling air through the hood (7). The upper part of the hood (7) has a neck (13) and is covered by a grid (10) to provide an inlet for cooling air to the motor (2). <IMAGE>

Title: Electric vehicle current regulator
Inventor: BERMAN MAX
IPC: H02P7/28
Filed: 1985-06-27
Abstract: A current regulator for a dc electric traction motor propelled vehicle, implemented using a microcomputer 112, incorporates an accelerator 50 having response characteristics similar to an accelerator in an internal combustion engine powered vehicle. The regulator uses a current feedback loop 122 to regulate motor torque to the value called for by the accelerator 50. However, if the magnitude of voltage as a percentage of available source voltage required to generate the desired current exceeds the percentage displacement of the accelerator, the applied voltage is limited to the percent accelerator displacement. In a braking mode the on/off time ratio of the regulator 14 is controlled in response to a comparison of actual motor current and desired braking current, established by the accelerator 50, the on times being fixed in duration and the length of the off times varied but maintained not less than a predetermined minimum. The electrical braking mode is canceled when the percent on-time reaches a maximum value. <IMAGE>
