    • A permanent magnet motor designed for d-c operation with pulsed current supply through at least two, and preferably four or more stator coils, has a rotor magnetized such that, with respect to 180.degree.-electrical, about 120.degree. are magnetized in one magnetic polarity, and the remaining about 60.degree. are magnetized with dual polarity to provide a monopole zone of magnetization and a dipole zone of magnetization, a galvano-magnetic sensing element being exposed to the path of circumferential rotation in which the same polarities of the dipole and monopole zones are contiguous for control of pulse current flow through the windings of the motor. A tacho generator winding may additionally be included in the air gap, exposed only to the rotary path of one magnetic pole of the dipole zone and the monopole zone.

    • A Hall generator flexibly held in an aperture of a circuit plate by its contact strips is pressed between a perpendicular elongated flux concentrator with a tapered nose and the center strip of a somewhat resilient flat flux concentrator. A mounting sleeve provides for force-fitting the elongated flux concentrator and for mounting the two flux concentrators in fixed position on the circuit plate on opposite sides thereof. After the elongated flux concentrator is pressed into a position for flushly clamping the Hall generator under the spring effect of at least the flat flux concentrator, the elongated flux concentrator is permanently set with a little adhesive around its upper periphery to insure continuance of the clamping force. The two flux concentrators come quite close to appropriate portions of an external rotor of a brushless d.c. motor.

    • An external-rotor brushless direct-current motor has a pair of rotor plates spaced axially apart and connected together for joint rotation about an upright axis. One of these plates carries an annular multipolar axially polarized magnet. A fixed stator plate extends between the two rotor plates and carries a plurality of angularly equispaced sequentially activatable windings. In addition a flux-return element of soft iron is carried on this stator plate and has an outer periphery formed with projections extending into the flux region of the magnet. These projections may simply be the corners or points of a polygonal flux-conducting element, or may be formed between recesses cut into the periphery of this element.

    • Control semi-conductor switches, such as switching transistors, are connected to the armature windings of the rotor, which has a permanent magnet rotor; the semi-conductor switches are energized by pulses derived from the control circuit, which includes a sensing circuit, such as diodes connected to the armature windings, to sense induce d-c voltages in the state of winding during operation of the motor, and a phase shift circuit, such as a multi-stage filter, phase shifting the sensed d-c voltages by, preferably about 180.degree.-electrical, the phase shifted signals then being used to control the timing of energization of the semi-conductor switches, for example by comparison of instantaneous values of the phase shifted d-c voltages with respect to a reference, so that the maximum current flow, due to pulse energization, will occur at the time of maximum induced voltages, and for a period of time depending on the relative instantaneous value of the phase shifted d-c voltage with respect to a reference voltage, resulting in optimum efficiency of operation of the motor.
