TL;DR: In this article, a control circuit for controlling the electricity supply of a winding phase (102) in an electric motor (134) is described, where a control unit (108) is configured in such a way that enables the output to be set to high-impedance, at least when the semiconductor switch (106) is disconnected, in order to prevent the signal from being influenced by the output (110) during the disconnection process.
Abstract: A control circuit (150) for controlling the electricity supply of a winding phase (102) in an electric motor (134). The control circuit (150) comprises a semiconductor switch (106) and a control unit (108) for controlling the semiconductor switch. The semiconductor switch (106) is connected to the winding phase (102) in order to control the electricity in said winding phase. The control unit (108) comprises an output (110) for the provision of a control signal (CTRL) for the semiconductor switch (106) and is configured in such a way that enables the output to be set to high-impedance, at least when the semiconductor switch (106) is disconnected, in order to prevent the signal from being influenced by the output (110) of the semiconductor switch (106) during the disconnection process.

24 Dec 2004TL;DR: In this paper, an electronically commutated electric motor (10) comprising at least one stator winding phase (12, 14) and a method for controlling one such motor was presented.
Abstract: The invention relates to an electronically commutated electric motor (10) comprising at least one stator winding phase (12, 14), and a method for controlling one such motor. The aim of the invention is to reduce power loss. To this end, the duration of the intervals (T-t) between the pulses of the control signals for feeding the at least one stator winding phase (12, 14) is essentially constant.

28 Dec 2004TL;DR: In this article, the stator winding was used for controlling the operating range of the power transistors of an electronically commutated motor to produce a constant current that is essentially constant during the respective supply of current.
Abstract: The invention relates to an electronically commutated motor (10) and to a method for controlling an electronically commutated motor (10). In order to reduce commutation noises, the invention provides that a component (48) is used for influencing the operating range of the power transistors (20, 22) so that they produce, via the stator winding (12, 14), a current that is essentially constant during the respective supply of current.

28 Nov 2001TL;DR: In this paper, outflow contouring devices are arranged about the outlet opening and are configured to at least reduce a vortex formation within a shearing layer that is generated during operation of the ventilator.
Abstract: A ventilator housing of a ventilator has a flow passage having an intake opening and an outlet opening. Outflow contouring devices are arranged about the outlet opening and are configured to at least reduce a vortex formation within a shearing layer that is generated during operation of the ventilator so as to surround an actual airflow of the ventilator and that is located between the airflow and surrounding air. The outflow contouring devices enlarge the proportion of uninterrupted air flow relative to the entire flow cross-section of the flow passage.

19 May 2004TL;DR: In this article, a rotational speed control of a two-pulse electronically switched motor with an auxiliary reluctance torque was proposed, where the rotor rotor was continuously collected and the rotor was adjusted to a value which is a difference function between the desired rotor rotor speed and the actual rotor speed.
Abstract: The invention relates to a method for rotational speed control of a two-pulse electronically switched motor which operates with an auxiliary reluctance torque (fig. 13:MR) and comprises at least one stator winding strand (32), a rotor (38) and a control unit (76) for controlling the motor (30) at a desired rotational speed (nsoll; t s). The inventive method consists in continuously collecting the characteristic value of the rotor (38). Above a determined minimum rotational speed (+NMIN, -NMIN), the operation of the motor (30) is adjusted to an independent value (BW) of a desired rotational speed. Above said minimum rotational speed (+NMIN, -NMIN), the operation of the motor (30) is adjusted to a value (BW) which is a difference function between the desired rotational speed (nsoll; t s) and an actual rotational speed (n; T HALL). A corresponding motor is also disclosed.
