Patent number: 9680347Abstract: The invention relates to an electric motor/gear mechanism unit including a housing, an iron-free rotor winding rotatably arranged in the interior of the housing, a collector connected to the rotor winding, a rotor shaft extending through the collector, and a gear mechanism which is connected to the rotor shaft and which has an output shaft. The present invention is so conceived that the gear mechanism is produced from a non-magnetic material and arranged in the interior of the rotor winding.Type: GrantFiled: August 1, 2014Date of Patent: June 13, 2017Assignee: MAXON MOTOR AGInventors: Daniel Sherwin, Albert Hugo Fritschy, Franzxaver Fölmli, Jens Oliver Schulze, Raniero Pittini, Dirk Zimmermann

Patent number: 8791607Abstract: The present invention relates to an electric linear drive, particularly for a rotary-lifting motor. Such a linear drive includes a winding system including a plurality of wound coils which are arranged to be coaxial to each other and successive in axial direction, and a magnet system which is movable in axial direction relative to the winding system and includes a plurality of axially successive permanent magnets. The winding system is normally fed by a controlled converter. The coils of the winding system and the permanent magnets of the magnet system define an air gap thereinbetween. Furthermore, a sensor is provided for detecting the relative movement of winding system and magnet system and for detecting the relative position of the two systems, the sensor being used for scanning a timing ruler mounted on the outer circumference of the magnet system.Type: GrantFiled: January 12, 2011Date of Patent: July 29, 2014Assignee: Maxon Motor AGInventors: Alexis Boletis, Hugo Fritschy, Remo Hofstetter, Jens Oliver Schulze, Raniero Pittini, David Ramon, Max Erick Busse-Grawitz

Patent number: 8569920Abstract: In a small electric motor having a stator and a rotor which includes a solid-cylindrical permanent magnet and at least one shaft element mounted on a face of the permanent magnet and bonded thereto by adhesive, the shaft element has at least one recess on its face facing the permanent magnet. The adhesive is introduced into the recess and contacting the face of the permanent magnet in the area of the recess.Type: GrantFiled: June 9, 2011Date of Patent: October 29, 2013Assignee: Maxon Motor AGInventors: David Ramon, Hugo Fritschy, Jens Oliver Schulze, Hans-Georg Jansing, Raniero Pittini, Minh Hieu Lam, Alexis Boletis
