  • Electric drive unit for a hand-held power tool
    Patent number: 12525904
    Abstract: Electric drive unit with a brushless DC motor and with a switching bridge for sensor-controlled commutation of the DC motor by at least one Hall sensor included in the DC motor, the Hall sensor being connected to the switching bridge and set up to detect an angle of rotation of the DC motor, and the drive unit also having a control unit, which is connected to the switching bridge and by which a setpoint speed for the DC motor can be specified, the control unit being set up to process Hall interrupts that are dependent on the angle of rotation and are caused by the at least one Hall sensor, and to determine an actual speed of the DC motor on the basis of time interrupts that are independent of the angle of rotation and the Hall interrupts that are dependent on the angle of rotation.
