Title:

MOTOR, AND PAN-TILT AND ROBOTIC ARM HAVING SAME

Document Type and Number:

WIPO Patent Application WO/2018/152944

Kind Code:

A1

Abstract:

A motor (100), and a pan-tilt (500) and a robotic arm (600) having same. The motor (100) comprises a support (11), a circuit board (13), a rotary shaft (21), and a permanent magnet (23). The circuit board (13) is mounted on the support (11) and comprises a coil circuit (138). The support (11) is mounted on the rotary shaft (21). The permanent magnet (23) and the coil circuit (138) are arranged adjacently and spaced. The permanent magnet (23) has an axial magnetization structure. The circuit board (13) is a carrier of the coil circuit (138) and replaces a conventional iron core, and the defects of cogging torque, magnetic hysteresis and eddy current loss occurring in existing motors are overcome. The action direction of a magnetic field of the permanent magnet (23) is designed to be axial main magnetic flux, end surfaces of the permanent magnet (23) and the circuit board (13) are axially butted and spaced, the axial size of the motor is reduced, and the mass and the volume of the motor are decreased.
