Electric motor has characteristic field stored as digital values for associating parameter and motor speed values, and microcontroller or microprocessor

Abstract: The motor (9) has its speed regulated by a variable physical parameter (2), especially a temperature. A characteristic field is stored as individual digital values for associating values of the physical parameter with corresponding motor revolution rate values. A microcontroller or microprocessor has access to the stored digital values. An Independent claim is also included for a method of regulating a physical parameter.

Electronically commutated asynchronous motor

Abstract: An electronically commutated asynchronous motor ( 12 ) features a stator ( 202 ), a short-circuit rotor ( 204 ), a controller (FOR 20 ) for field-oriented regulation of the motor ( 12 ), a sensor magnet ( 274 ) in thermally conductive connection with the short-circuit rotor ( 204 ), a rotor position sensor ( 14 A; 18; 18 ′) arranged at a predetermined distance (d) from the sensor magnet ( 274 ) to generate an output signal (HALL, U, U 1 , U 2 ) that is dependent upon the spatial orientation of the sensor magnet ( 274 ), and a temperature evaluation apparatus (CALC_T 44 ) configured to ascertain, during operation, from the sensor output signal (HALL, U, U 1 , U 2 ), a temperature value (T) that characterizes a temperature (T_SM, T_S) in the motor ( 12 ).

Circuit for Thermal Protection and Power Regulation of Electric Motors

Abstract: A circuit for thermal protection and power regulation as a function of the current winding temperature of phase windings of an electric motor. The circuit including at least one temperature monitor switch (TW 1, TW 2 ) that measures the winding temperature of the phase windings, and that upon attainment of a specific winding temperature shuts off the winding current flowing through the windings, the circuit further including a PTC thermistor that is associated with the phase windings and that, upon attainment of a specific winding temperature, reduces power by means of a resistance increase, or shuts the motor off. One of the phase windings has the PTC thermistor. The other phase windings or winding has a temperature monitor switch. The PTC thermistor and the temperature monitor switch or switches (TW 1, TW 2 ) are connected in series to a voltage source.

Rotor for an electric external rotor motor and external rotor motor

Abstract: Disclosed is a rotor ( 1 ) for an electric rotor motor, consisting of a rotor bell ( 2 ) with a peripheral wall ( 4 ) and at least one one-sided rotor base ( 6 ) to enclose a stator, in particular as a part of a motor housing with a high IP rating, for example IP54 per DIN/IEC-EN 60034-5. The rotor bell ( 2 ) features a heat sink ( 12 ) with high heat conductivity that extends through the rotor base ( 6 ) in such a way that the motor heat arising on the inside can be removed via the heat sink ( 12 ) through the rotor base ( 6 ) to the outside into the environment. Further, the invention relates to an electric rotor motor, in particular with an encapsulated motor housing with a high IP-protection system, for example IP54 per DIN/IEC-EN 60034-5, consisting of a stator and a rotor ( 1 ) enclosing the stator in an embodiment of the above-described type.

Lüftereinheit mit einem Axiallüfter

Abstract: Eine Luftereinheit hat einen Axiallufter (20; 120), welchem ein Luftfuhrungsrohr (22; 122) zugeordnet ist, durch welches der Lufter (20; 120) im Betrieb Luft transportiert, welches Luftfuhrungsrohr (22; 122) mit mindestens einem Aufhangeglied (23; 123) aus einem elastomeren Werkstoff verbunden ist, welches Aufhangeglied (23; 123) in einem aus einem harten Kunststoff gebildeten, ersten Ring (40; 140) elastisch aufgehangt ist, welcher erste Ring (40, 140) mindestens einen aus einem weichen Kunststoff gebildeten, rohrartigen Fortsatz (50, 150) zur gerauschdampfenden Verbindung der Luftereinheit mit einem Tragerteil (15) aufweist.
