摘要： A system for driving an electric handpiece in response to a pneumatic control signal may provide for fast interchange of handpieces, self-calibration and wide dynamic range of operation with precise speed control. The system may be incorporated into virtually any dental treatment center using traditional pneumatic drive handpieces, and a conversion kit may facilitate such conversion. The system may provide not only for controlling the speed and torque of a tool coupled to an electric drive handpiece responsive to a pneumatic control signal, it may also provide for coupling cooling air and treatment media, such as air and/or water to the handpiece. Coupling of a handpiece to an operating base of the system, including coupling of media lines and electrical connections may be made with a simple press and twist action using quick connection structure.

摘要： In a method of operating a brushless electric motor, having a permanent magnet rotor and a stator with three windings electrically offset by 120°, provided for example for driving a dental treatment instrument, the zero crossings of a voltage induced by rotation of the rotor in the stator windings is detected by a comparison of a voltage at an inactive stator winding in a monitoring phase with a comparison voltage, and on the basis of the detected zero crossings there is determined the speed of rotation of the motor and/or a suitable commutation point for an intermediate circuit voltage delivered to the stator windings. The comparison voltage is formed by the voltages at the two further, active stator windings in the monitoring phase.

摘要： The invention relates to a turbine wheel (7) for a gas operated medical, in particular dental-medical, handpiece (3), having a plurality of blades (2) which extend in radial direction from a hub (7c) and extend in axial direction from a side ring web (29) of the turbine wheel (7), and the front side (22a) of which is substantially concavely curved about an approximately radially running first axis of curvature (23). In order to increase the drive power or to better exploit the drive power the rear side (22b) of the blades (22) has at least in an axial end region an inclination surface (35) which is inclined in the axial direction towards the front side (22a).
