摘要： A control system (100) for a five-phase brushless DC motor (102) including a stator having five windings and a rotor (116) mounted for rotation relative to the windings (114). The windings (114) are adapted to be electronically commutated in response to the rotary position of the rotor (116). The control system (100) includes a sensing circuit (106) to sense the rotary position of the rotor (116) using an optical or magnetic sensor or the back electromotive force voltages in the windings (114). Electronic switches (112) control the flow of current through the windings (114) in response to control signals generated by a control circuit (110) in response to the rotary position of the rotor (116). The control circuit (110) includes start-up logic to start the motor (102). If the rotor (116) is rotating in a wrong direction upon start-up, the control circuit (110) energizes preselected windings (114) and waits for the movement of the rotor (116) to come substantially to a stop and then energizes the windings (114) in a start-up sequence to cause the rotor (116) to rotate in a correct direction. Once the rotor (116) is rotating in the correct direction, the control circuit (110) electronically commutates the windings (114) in response to the rotary position of the rotor (116).

摘要： The following steps are required when starting a dual-pulse electronically switched direct current motor in the desired direction of rotation, which is designed for functioning in a preferred direction: after being switched on, a start routine (S118) using alternating current in one and then the other direction of rotation sets the motor's rotor in forced oscillation about a rest position; the start routine controls whether the rotor starts turning; once established that the motor has started, the start routine is abandoned. In addition, a process is described in which the current of one branch is switched on to optimize the rotation setting of the rotor, depending upon the RPM and the direction of rotation.
