Publication number: 20240102486Abstract: A turbomachine has a housing with at least one flow channel, an impeller which is arranged in the housing, and a drive motor. The drive motor is used to drive the impeller in order to suction a fluid into the housing through the at least one flow channel and/or to convey the fluid out of the housing through the at least one flow channel. The housing is produced by an additive manufacturing process. Further disclosed is a turbomachine in which the impeller is produced in an injection molding method and is molded directly onto the rotor of a drive motor designed as an external rotor motor.Type: ApplicationFiled: November 4, 2021Publication date: March 28, 2024Applicant: Micronel AGInventors: Peter Meier, Ernst Scherrer

Patent number: 11754092Abstract: A radial turbomachine has a first housing part and a second housing part, which jointly form and delimit a flow channel. The first housing part forms a motor chamber for accommodating a drive motor, and the second housing part forms a gas inlet. Furthermore, a radial impeller is provided, which can be driven about an axis of rotation by the drive motor in order to suction a gas from outside the turbomachine through the gas inlet into the flow channel and to convey said gas out of the flow channel through a gas outlet to the outside. The first housing part or the second housing part forms the gas outlet at a radial distance from the axis of rotation and peripherally delimits the gas outlet.Type: GrantFiled: May 6, 2019Date of Patent: September 12, 2023Assignee: Micronel AGInventors: Ronny Zwahlen, Daniel Hilpert, Peter Meier, Ernst Scherrer

Publication number: 20110181140Abstract: A stator has a first bearing for a first end of a shaft of the rotor, and a second bearing for a second end of the shaft. The first and the second bearings have a respective permanent magnet which exerts a magnetic force on the shaft. Alternatively, the shaft is in the form of a permanent magnet and the first and the second bearing have a respective ferromagnetic part. At least one of the two ends of the shaft is supported axially by means of a point bearing. The apparatus is, for example, a fan.Type: ApplicationFiled: December 16, 2010Publication date: July 28, 2011Applicant: Micronel AGInventor: Ernst Scherrer

Publication number: 20110146966Abstract: The cooling device has a fan having a fan wheel, and a heat sink, through which there is a flow for cooling purposes when the fan wheel rotates. The heat sink has guide vanes deviating from the radial direction and is embodied as an integral shaped part. In particular, the guide vanes are embodied in spiral fashion. The cooling device serves, in particular, for cooling an LED lamp.Type: ApplicationFiled: December 16, 2010Publication date: June 23, 2011Applicant: Micronel AGInventor: Ernst Scherrer

Publication number: 20080292947Abstract: The apparatus has a carrier for accommodating a plurality of series-connected energy cells, which each have a positive terminal and a negative terminal. An electrical contact is provided in the carrier for each terminal, which electrical contacts, when the energy cell is inserted, connect said energy cell to connection points for drawing energy. Each positive terminal and in each case the associated negative terminal are electrically connected to one another via a switch. These switches are designed such that they are in each case interrupted when an energy cell is inserted. The invention then also makes possible current consumption if fewer than the maximum possible number of energy cells are available.Type: ApplicationFiled: November 13, 2007Publication date: November 27, 2008Applicant: MICRONEL AGInventor: Ernst Scherrer

Patent number: 7204193Abstract: The mobile holding apparatus has a support plate which has an upper side with a work surface and a lower side and is mounted height-adjustably on a stand. The stand is free-standing and the support plate has a guide with which it is guided on the stand. A gas spring arranged in the stand supports the upward movement of the support plate. Loading of the support plate is taken up by self-locking of the guide and in particular by canting of a profiled piece in a guide groove. The holding apparatus makes possible ergonomic positioning of a work aid, for example a laptop.Type: GrantFiled: May 13, 2004Date of Patent: April 17, 2007Assignee: INOTOP AGInventors: Ernst Scherrer, Peter Meier

Patent number: 6066910Abstract: A direct-current motor has a single coil having a plurality of active branches and a rotor having a permanent magnet. The active branches are arranged in sequence essentially without gaps. The permanent magnet has magnetic segments which overlap all the active branches. The number of magnetic poles is at least equal to the number of active branches. As a result of the magnetic overlap of the coil and the permanent magnet, a greater efficiency is achieved.Type: GrantFiled: March 30, 1999Date of Patent: May 23, 2000Assignee: Micronel AGInventor: Ernst Scherrer

Patent number: 5217351Abstract: The small fan has an air conduction housing (2) of plastic, in which an impeller (1) is rotatably supported. It is designed as a meridian-accelerated fan. The blades (1a) of the impeller (1) are not twisted and have the same angle of pitch over the entire blade length. The leading edges of the impeller (1b) and the front side of the hub (1c) as well as the front side of the housing (2d) lie approximately in the same plane. In contrast to axial fans, the meridian-accelerated fan has a higher power density along with a lower noise development.Type: GrantFiled: April 19, 1991Date of Patent: June 8, 1993Assignee: Micronel AGInventors: Peter Meier, Ernst Scherrer

Patent number: 4968910Abstract: An axial securing device for the shaft of a small motor in which one end of the shaft is solidly connected with a rotor and the other end is supported in a thrust bearing of a stator. A securing element is locked into an annular groove of the shaft. The securing element has an inwardly directed bulge and a cylindrical projection. When the shaft is inserted, the securing element is pushed in front of the annular groove during the radial extension and locks into the annular groove by itself during further axial movement. The projection is so dimensioned so that through this movement its underside surrounds the contact surface of the shaft end.Type: GrantFiled: August 31, 1989Date of Patent: November 6, 1990Assignee: Micronel AGInventors: Peter Meier, Ernst Scherrer
