  • Brushless electric motor and instrument for a medical apparatus
    Patent number: 7535135
    Abstract: A brushless electric motor which has a rotor magnet, a coil apparatus for electromagnetically driving the rotor magnet, a rotor shaft for transmitting a rotary movement, which is firmly connected to the rotor magnet and runs through a rotation axis of the rotor magnet, and at least one electromagnetic transducer element for detection of the magnetic field of the rotor magnet, in which the at least one electromagnetic transducer element is arranged outside the axial extent of the rotor magnet with respect to the rotation axis, and is arranged essentially within the maximum radial extent of the rotor magnet. The invention also relates to an instrument for a medical, in particular a dental, apparatus having a brushless electric motor such as this.
