CONTROL CIRCUIT FOR A DC MOTOR WITHOUT MANIFOLD, PARTICULARLY A FAN |
| abstract |
A DC motor without collector comprises an annular rotor R forming a four-pole magnet, and housing a stator with two branches S1 and S2 provided with windings LS1 and LS2 and pole pieces PS1 to PS4. The control current is switched between the members LS1 and LS2 according to the position of the stator relative to a Hall effect sensor H. According to the invention, this command acts each time by closing the switching transistor concerned after a delay, and for the rest of the stator control period. |
