20140167531 | ROTOR AND ELECTRIC MOTOR - A rotor for an electric motor, in particular for synchronous motors of wet-running pumps, with a rotor core on the periphery of which a number of magnets are arranged, the rotor core and the magnets being surrounded by a plastics material casing. The magnets each have a receiving groove on a peripheral face remote from the rotor core. | 06-19-2014 |
20140140872 | ELECTRIC MOTOR - An electric motor with a casing in which a stator in coaxial arrangement with the motor shaft and a rotor are disposed, and a terminal box which is attached to a casing peripheral wall and in which electronic components are arranged. Between the terminal box and the casing a breakthrough is provided on the one hand and an auxiliary impeller firmly connected to the motor shaft is mounted inside the motor casing on the other hand such that an air stream can flow from the interior of the casing into the interior of the terminal box and/or vice versa when the electric motor is operating. | 05-22-2014 |
20130236297 | PUMP - Pump, in particular a canned motor pump, to deliver liquids in water carrying domestic appliances and such like, which comprises a stator, a rotor and a drive shaft non-rotatably coupled to an impeller disposed in a pump compartment which is rotatably arranged inside a motor casing via bearing means wherein seal means are fitted on a first face end of the motor casing to seal said casing off against the pump compartment, wherein the bearing and seal means arranged on the first face end of the motor casing are in the form of a seal-bearing combination which comprises an axial bushing section for sliding arrangement on the drive shaft, a radial closing section to cover up the motor casing and at least one flexible seal element formed to said axial bushing section and/or said radial closing section. | 09-12-2013 |
20130002063 | DEVICE FOR DYNAMIC BALANCING OF A ROTATING COMPONENT - A device for limiting an unbalance in inside a centrifugal, with an electric motor to drive a rotating component disposed in an enclosure around a rotational axis, wherein a rotor of the electric motor is non-rotatably connected to the rotating component, a bearing assembly for the rotor and the stator to be arranged in, and a stabilizer unit which generates as a function of a disturbing force acting on the rotating component a balancing force that is adapted to compensate said latter, the bearing assembly including support means such as to make the stator radially movable, and the stabilizer arranged radially outside and/or inside said stator and/or support means of the bearing assembly and having stabilizing means whereby in aggregate a radial balancing force can be generated. | 01-03-2013 |
20120007578 | ELECTRIC MOTOR - An electric motor with an n-pole stator comprising a first stator winding and a second stator winding that can alternatively be supplied with current for the constitution of a pole-changeable electric motor. The supply winding is constituted by at least one turn of the first stator winding or of the second stator winding. Thus, a conventional winding design or coil design of the electric motor can be used to provide a supply voltage for electric equipment. The electric motor features an unchanged compact construction. Only at particular locations of existing stator turns current is tapped, such that a supply voltage of predetermined magnitude can be tapped based on the existing magnetic flux linkage during operation of the electric motor. | 01-12-2012 |
20120001505 | ELECTRIC MACHINE - Electric machine, in particular an electric motor, which comprises a motor support, a stator, a rotor, a fan arranged at the face end of said motor and an electronics casing disposed adjacent to the motor support for electronic components to be arranged in wherein a face-end wall of the motor support which is assigned to the fan is provided with an axial opening such that an air stream discharged from the motor support is by means of said fan deflected toward the electronics casing. | 01-05-2012 |
