Document Type and Number:
WIPO Patent Application WO/2020/183523
Kind Code:
A1
Abstract:
This motor (1) has a rotor (2), a stator (3), and a magnetic sensor (5). The rotor (2) has a rotor core (21), a permanent magnet (22), and a sensor magnet (24). The magnetic sensor (5) detects magnetic flux from the sensor magnet (24). When Rh1 is the shortest distance from the rotary axis (Ax) of the rotor (2) to the magnetic sensor (5), and Rm1 is the shortest distance from the rotary axis (Ax) to the permanent magnet (22), the motor (1) satisfies Rh1>Rm1.
