Patent number: 9537376Abstract: An electric motor arrangement for a medical, especially dental, tool handle, which is extremely compact and resistant to sterilizing temperatures due to a plurality of advantageous embodiments. The electric motor arrangement is characterized by the following properties: the use of a light source based on SMD-LED or LED as a semiconductor chip; the shortening of the INTRAmatic coupling to between 20 mm and 25 mm; a hermetically extruded stator comprising integrated media tubes and molded connection sockets; the stator winding is embodied as a coil segment winding instead of an H winding or triangle; and the winding head has openings for media tubes.Type: GrantFiled: August 29, 2013Date of Patent: January 3, 2017Assignee: KALTENBACH & VOIGT GMBHInventors: Josef Duesing, Alfons Mader, Johann Stempfle

Patent number: 9522049Abstract: An electric-motor arrangement for a medical, in particular dental, handpiece that has a motor housing and a rotor which is arranged in the motor housing so that it can be rotated about an axis via a first bearing and a second bearing. A stator is arranged around the rotor in relation to the axis. The first bearing is received in a first bearing flange, and the second bearing is received in a second bearing flange. Both bearing flanges are composed of metal and adjoin the motor housing directly by way of their circumferential faces. As a result, running noise and vibrations can be reduced. Moreover, premature wear and/or failure can be prevented.Type: GrantFiled: December 4, 2013Date of Patent: December 20, 2016Assignee: Kaltenbach & Voigt GmbHInventors: Josef Duesing, Alfons Mader, Johann Stempfle

Patent number: 8853895Abstract: The invention relates to an electric-motor arrangement for a medical, in particular dental, hand piece which has a motor housing (2) and a rotor (4) which is arranged in the motor housing (2) so that it can be rotated about an axis (L) via a first bearing (6) and a second bearing (8). A stator (14) is arranged around the rotor (4) in relation to the axis (L). The first bearing (6) is received in a first bearing flange (10), and the second bearing (8) is received in a second bearing flange (12). Both bearing flanges (10, 12) are composed of metal and adjoin the motor housing (2) directly by way of their circumferential faces (101, 121). As a result, running noise and vibrations can be reduced. Moreover, premature wear and/or failure can be prevented.Type: GrantFiled: April 22, 2011Date of Patent: October 7, 2014Assignee: Kaltenbach & Voigt GmbHInventors: Josef Duesing, Alfons Mader, Johann Stempfle

Patent number: 7789602Abstract: A motor element for a dental medical handpiece or a motor spindle has an elongated shank, rotatably mounted in which there is a drive shaft and a longitudinally-extending rod, a tool-holder for a tool within the rod, and a disconnectable coupling between the rod and the tool-holder. A locking element secures the coupling to prevent the coupling from becoming disconnected from the elongated shank. The locking/unlocking of the coupling is effected by a relative movement between the tool-holder and the tool.Type: GrantFiled: April 6, 2006Date of Patent: September 7, 2010Assignee: Kaltenbach & Voigt GmbHInventor: Josef Duesing

Publication number: 20070184407Abstract: The invention relates to a motor element, in particular to a dental medical handpiece or a motor spindle, which at least in its front region has an elongated shank, rotatably mounted in which there is a drive shaft, having a tool-holder for a tool, having a disconnectable coupling between the drive shaft and the tool-holder, and having a locking means for the coupling in order to prevent the latter from being disconnectable. In order to improve the coupling of the tool-holder, the locking means is formed by the tool in such a way that the locking/unlocking is effected by a relative movement between the tool-holder and the tool.Type: ApplicationFiled: April 6, 2006Publication date: August 9, 2007Applicant: Kaltenbach & Voigt GmbHInventor: Josef Duesing
