Title:
SHORT-WHEELBASE LARGE-MAGNETIC-FORCE ELECTRIC MOTOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/017062
Kind Code:
A1
Abstract:
Disclosed is a short-wheelbase large-magnetic-force electric motor system. A first output interface is arranged at a second end of a rotor shaft; a rotor winding is fixed on a shaft body of the rotor shaft; a second through hole is formed in the center of a rotation disc shaft; an inner circumferential wall of a rotation disc concentrically envelops an outer circumference of the rotor winding; a stator winding is fixed to the inner circumferential wall of the rotation disc, an inner fluted disc is coaxially arranged on an inner circumference of a second end of a shell, a planet wheel meshes between an inner circumferential wall of the inner fluted disc and an outer circumferential wall of the rotation disc, and a second output interface is arranged in an outer end wall of the inner fluted disc; a first bolt is axially and telescopically arranged in the center of an outer cover shaft, a bayonet is provided in a position, corresponding to the first bolt, of a first end wall of the rotor shaft, and an inner side end of the first bolt is selectively clamped and fixed in the bayonet; and a second bolt is radially and telescopically arranged on the shell, clamping teeth are arranged at an inner side end of the second bolt, and the clamping teeth are selectively clamped and fixed in inner tooth grooves. Rotational speed selectivity is provided for a client, such that a servo electric motor is more suitable for an application occasion, and servo control accuracy is improved.
