    • An apparatus serves to sense the absolute value of the rotational position of a shaft (14). The apparatus has a first single-turn rotary encoder (30) that is arranged at one end (20) of the shaft (14) and is arranged to sense the latter's rotational position within a single shaft revolution. Also provided are: a multi-turn rotary encoder unit which senses the number of revolutions of the shaft (14) and which comprises a reduction gear linkage (18); a rotary element (42), driven by the output of the linkage, that is oriented as an imaginary continuation of the shaft (14) and coaxially therewith; and a second single-turn rotary encoder (48) which is arranged to sense the rotational position of the rotary element (42) within a single revolution. The reduction gear linkage (18) surrounds the shaft (14), and its output element (38) is connected, via a connecting member (40), to said rotary element (42) around the first single-turn rotary encoder (30). An unusually compact combination motor/encoder unit can thereby be achieved, suitable for installation in small spaces, e.g. a few centimeters wide.

    • The invention relates to a method for adjusting a real value (actual value) of a physical quantity to a preset value (target value) with the following steps:(a) the difference between the target value and the actual value (referred to below as the control deviation) and its sign (referred to below as the control sign) is determined repeatedly at interval; (b) the control deviation is converted into at least one electrical signal during or after each measurement, and the duration thereof (referred to below as the control deviation duration) is proportional to the absolute value of the control deviation at least in the range of the target value, and the value thereof is a function of the control sign; (c) the charge of an analog electrical memory arrangement is affected by this at least one electrical signal during the control deviation duration; (d) depending on the value of the charge of the memory arrangement, the physical quantity is directly or indirectly affected to keep it in the range of the target value. Said control method, which is partially based on analog and partially on digital components produces, for a motor which uses a microprocessor for commutating or controlling, a rotation speed controller with a very simple structure.

    • An electronically commutated motor (10) has a permanent-magnet external rotor (58) and an inner stator (20) with claw-poles (30,32; 44,46). Preferably, the claw-poles extend axially from opposite directions along the outside of the stator (20) and are interdigited. A galvanomagnetic sensor (14) generates a rotor position signal, based upon measurement of a stray or cross-flux field (.phi..sub.1) of the rotating permanent-magnet external rotor (58,66). Between the claw-poles of the stator (20) are a plurality of neutral field zones (52). The motor turns in a predetermined direction (72) and the galvanomagnetic sensor (14) is positioned adjacent the stator (20) at a location which is circumferentially displaced with respect to a neutral field zone (52), in order to trigger early commutation of current to windings (22,24) of the motor (10). The stator structure includes a soft ferromagnetic element (28) which is formed with a cutout (76,76') adjacent the sensor (14) in order to increase the effective flux exerted on the sensor by the field of the rotor, and to thereby improve the precision of the rotor position signal generated by the sensor (14) during operation of the motor (10). The motor includes a control circuit actuated by the sensor output signal (86) which commutates current through the motor windings (22, 24).

    • An improved motor for driving a variable-speed fan used, for example, to prevent overheating of electronic equipment, features an electronic controller which sends current pulses through the stator winding(s) of the motor, and varies the slope of trailing edges of these pulses in accordance with at least one sensed operating parameter of the motor, such as temperature of the power semiconductors which control the motor current. The slopes are steepened at high motor speeds to reduce electrical losses, and flattened at low motor speeds to minimize noise. Another feature of the improved motor provides for fail-safe, high-speed operation of the fan when the sensed value of the operating parameter is implausible, for example when a lead from a temperature-dependent sensing resistor breaks. In a preferred embodiment, a bridge circuit is used, which includes a transistor in one diagonal of the bridge circuit. Currently marketed personal computers use central processor chips containing several million transistors, which generate heat, and adequate, reliable cooling is absolutely essential to their proper operation. The present invention improves reliability.
