Abstract
An integrated container-type torque-driven electric sensor for a vehicle motor is provided. Disposed on a motor housing along the direction of a motor shaft is a hollow cavity formed by a ring-shaped protrusion; contained in the hollow cavity is a fixed guiding slip ring; the fixed guiding slip ring dynamically matches with a floating sensor ring assembly having ratchet teeth and a magnetic steel piece; the ratchet teeth of a flywheel mating with the cogging distributed in a ring shape in a sensor ring having ratchet teeth; disposed on the motor shaft is a Hall element, the magnetic steel piece cooperating with the Hall element by means of magnetic induction, thereby outputting an electric signal to control a vehicle to enhance the force for rotation. For this motor, all Hall elements are disposed on the motor's housing, thereby solving the conflict between functional configurations and limited accommodation, and enabling significant magnetic induction effects.
