Title:
HALL PLATE CAPABLE OF SHIELDING INTERFERENCE
Document Type and Number:
WIPO Patent Application WO/2018/107540
Kind Code:
A1
Abstract:
A Hall plate (100) capable of shielding interference, comprising a shielding plate (10) and a Hall plate body (20). A first surface (201) of the Hall plate body is provided with a first Hall sensor (210) used for detecting motor body magnet position, and a second surface (202) thereof is provided with a second Hall sensor (220) used for detecting the magnet position of an external device coordinating with the motor. The shielding plate is welded onto the Hall plate body, preventing the influence of the motor body magnet on the second Hall sensor and the interference of the magnet of the external device coordinating with the motor with the first Hall sensor without affecting the detection of the motor body magnet position, the motor being able to function normally.
