Rotor for an electric outer rotor motor and outer rotor motor

Abstract: The rotor (1) has a rotor socket (2) provided with a peripheral wall (4) and a single-sided rotor base (6) for enclosing stator as a part of motor housing with high degree of protection system of Ingress Protection 54according to DIN/international electro-technical commission-EN 60034-part 5. The rotor socket comprises a heat sink (12) with high thermal conductivity such the motor heat that occurs in an inner side is discharged to surrounding area via the heat sink through the rotor base. The heat sink is formed as a single-piece disk-type cooling element (20).

Radial or diagonal fan wheel

Abstract: The present invention relates to a fan wheel in a version as a radial or diagonal fan, of a baseplate and of a plurality of fan blades arranged so as to be distributed over the circumference of the inlet port and around an axis of rotation. The fan wheel has a shroud with an inlet port and the shroud and/or the baseplate have/has in this case a nonrotationally symmetrical geometry which in each case has a continuous and point-invariable profile, as seen in the axial or axially parallel direction.

Device for detecting absolute angle of shaft, especially of electric motor, has single turn rotation sensors for detecting positions of shaft and rotary element in multi-turn rotation sensor

Abstract: The device has a first single turn rotation sensor on an end of the shaft for detecting its angular position within one turn and a multi-turn sensor unit for detecting the number of rotations of this shaft with a reduction gear driven by the shaft, a rotary element connected to its output on an imaginary extension of and coaxial to the shaft and a second single turn sensor for detecting the position of the rotary element within a single turn. The device has a first single turn rotation sensor (30) on an end of the shaft (14) for detecting its angular position within one turn and a multi-turn sensor unit for detecting the number of rotations of this shaft with a reduction gear (18) driven by the shaft, a rotary element (42) connected to its output on an imaginary extension of and coaxial to the shaft and a second single turn sensor (48) for detecting the position of the rotary element within a single turn.

Elektromotor mit funktionsüberwachung der motorlager

Abstract: Die vorliegende Erfindung betrifft einen Elektromotor (1), umfassend einen Stator (2) mit einem relativ zu diesem drehbar in Lageranordnungen (11) gelagerten Rotor (4) sowie ein Motorgehause (3, 12) und einen Schwingungssensor (16) zur Aufnahme von im Elektromotor (1) auftretenden Schwingungen, die durch Funktionsstorungen an den Lageranordnungen (11) verursacht werden. Es ist hierbei die Ausbildung als Ausenlaufermotor vorgesehen. Der Stator (2) weist ein Lagertragrohr (7) auf, das einendig mit einem ringformigen Statorflansch (8) verbunden ist. In dem Lagertragrohr (7) sind in Richtung einer mittleren Langsachse (X-X) des Lagertragrohrs (7) zueinander beabstandete Lageranordnungen (11) angeordnet, in denen eine Welle (9) des Rotors (4) gelagert ist. Der Schwingungssensor (16) ist am Statorflansch (8) befestigt.

Electric motor with rpm-monitor

Abstract: The motor comprises a speed transducer. A ring magnet (8) of the speed transducer (8, 9) plugs into an inner wall of the motor end plate (3).
