The DC motor (20) has a stator provided with at least one stator winding (22,24,26) and a cooperating rotor (28), positive and negative supply lines (76,78) connecting the motor to a battery (77) and a full-bridge circuit (74) controlling the stator winding current, with upper bridge path transistors (66,80,86) between the positive supply line and respective stator windings and lower bridge path transistors (70,84,90) between the negative supply line and the stator windings. The bridge circuit transistors are controlled by different rotor position signals combined via a control transistor (60). |
