摘要： A multi-phase brushless d.c. motor comprises a permanent-magnet rotor (1) and a stator (2) with stator coils (16, . . . , 21) arranged between three power lines (A, B, C). For the purpose of commutation the motor is provided with switching devices (22A, 22B, 22C) for the cyclic disconnection and connection of the power-supply lines (A, B, C) of the motor to a d.c. power source (25). Each switching device (22) comprises a section (42) which is controlled by the rotor-magnet field for deriving the disconnection instants and a section (43) for deriving the connection instants from a voltage change which is produced on the power-supply line connected to the switching device as a result of another power-supply line being disconnected.

摘要： An electrical multipole machine comprises a first machine section (1), a second machine section (3) and a machine shaft (5), about which one machine section is rotatable relative to the other machine section. The first machine section comprises an annular permanent-magnet body (11) having a plurality of adjacent pole pairs (N; S). The second machine section comprises a lamination assembly (25) having teeth (27-35) and coils (37-45). The teeth comprise tooth surfaces (47-55) which are geometrically spaced from one another by slots (57-65) and from the magnet body by an air gap (67). Near the air gap the slots extend in a tangential direction over at least 80 electrical degrees and at the most 90 electrical degrees, or over at least 130 electrical degrees and at the most 150 electrical degrees. The ratio between the number of poles and the number of teeth is either 4:3 or 2:3.

摘要： A device which detects the angle of rotation of a rotor with respect to a stator of a brushless multi-phase d.c. motor. The rotor comprises a permanent magnet and the stator comprises a plurality of electrical windings. Electric drive signals are applied to the windings in order to drive the rotor. The device includes a drive circuit for applying pulse-shaped electric test signals to the windings while the rotor does not rotate. A measurement circuit detects flyback pulses generated by the motor in response to the test signals. A processing unit processes the durations of the detected flyback pulses in combination in order to determine the angle of rotation. On the basis of the angle of rotation thus determined, the motor can be started such that the rotor is set into rotation in a predetermined direction of rotation.

摘要： A brushless DC motor is self-starting using only one magneto-sensitive element because the motor is of a two-phase type and is provided with a detection device which detects towards which of the two phases the rotor is mainly directed. A presetting circuit compares the detected rotor position with the state of an energizing circuit in order to set this circuit so that the energizing circuit energizes the stator phases for said specific rotor position in such a way that starting of the motor is guaranteed, although initially with an undefined direction of rotation. By presetting the commutating direction of the energizing circuit the rotor subsequently locks onto the field and rotates in the correct direction if it has started in the incorrect direction.
