Electronically commutated internal rotor motor

Abstract: An electronically commutated internal rotor motor (20) has an outer stator (28) and a permanent magnet rotor (36) arranged rotatably therein by means of a shaft (40) supported at its drive end (42) by a rotary bearing (54) located in the A-side bell (26) and supported at its other end (44) by a rotary bearing (72) located in the B-side bell (66). The rotary bearing (54) in the A-side bell is preferably so configured that it permits a small radial movement (56) of the drive end (42) relative to this bell (26). The rotary bearing (72) in the B-side bell (66) has its outer race (72) tensioned against a shoulder (90, 94). Its inner race (74) is tensioned between a shoulder (78) of the shaft (40) and a shaped part of non-ferromagnetic material. This shaped part is pressed by a countersunk screw (82), screwed into a threaded bore (84) of the other shaft end (44), against the inner race.

Gebläse mit Laminar-Element vor der Ansaugöffnung

Abstract: Es wird ein Radialgeblase (1) mit einem Gehause (2) und einem darin angeordneten Geblaserad (3), einem Lufteinlass (4) und einem Luftauslass (5) angegeben, wobei zwischen letzteren ein Druckraum (6) ausgebildet und vor dem Lufteinlass (4) ein Stromungsgleichrichter angeordnet ist, der in einem darin ausgeformten Bypass (8) einen Sensor (9) zur Erfassung mindestens eines Parameters des durch den Lufteinlass (4) stromenden Mediums umfasst.

Axial fan arrangement for ventilation of low-power building, has flow-controlling arrangement generating speed-reference value for electrically commutated motor, and speed controller controlling speed of motor to speed-reference value

Abstract: The arrangement (100) has a flow sensor for determining air-volume flow (125) produced by an axial fan (120) and for production of a volume flow-measured value (Vmess). A volume flow-controlling arrangement (160) controls the air volume flow to a predetermined volume flow-reference value (V-s). The volume flow-controlling arrangement is designed to generate a speed-reference value (N-s) for an electrically commutated motor (110) . A speed controller (170) controls the speed of the motor to the speed-reference value. An independent claim is also included for a controlling arrangement for a fan.

Electric fan with strain relief connection

Abstract: A fan has a hub and a fan housing connected to the hub. The fan housing delimits an air passage of the fan outwardly. A fan wheel is connected to the hub and rotatably arranged in the air passage. A motor is arranged on the hub for driving the fan wheel. An electrical connection with at least one flexible line is connected to the motor and extends from the motor to the fan housing. A recess is provided within the fan housing and the flexible line extends from the motor to the recess. A holding member locks in place in the recess and deflects the flexible line at least at one deflection location about a predetermined minimum angle to thereby effect strain relief on the portion of the flexible line extending from the deflection location to the motor.

Method for allocating network addresses for ventilators

Abstract: The method involves providing an adjustable network address memory (9) for each of ventilators (3,4,5) and assigning an identical start-address as network address to all of the ventilators. A serial number queries is sent with a serial number mask which are being sent to the network address. The ventilators unique network addresses are assigned or the serial number mask is modified for serial number queries by using a control unit (1). Independent claims are included for the following: (1) ventilator; and (2) control unit.
