Title:
MAGNETISM DETECTION UNIT, ANGLE DETECTION DEVICE, POSITION DETECTION DEVICE, MOTOR CONTROL DEVICE, MOTOR UNIT, AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/230203
Kind Code:
A1
Abstract:
Provided is a novel technology for detecting the absolute position of a subject using a Hall effect sensor. A magnetism detection unit (2) has two Hall effect sensors (first Hall effect sensor H1 and second Hall effect sensor H2). The two Hall effect sensors are connected to each other in series at the input side of the respective Hall effect sensors.
