Device for detecting the end position of a servomotor and robot joint servomotor

Abstract

Device for detecting the end position of a servomotor and a robot joint servomotor. The present invention relates to a device for detecting the end position of a servomotor and a robot joint servomotor. The servomotor comprises a motor stator, a motor rotor (1), and a motor housing. The detection device comprises: a first gear (2), a second gear (4), a first magnetic encoder (3), and a second magnetic encoder (5). The first gear (2) is fixedly connected to the end of the motor rotor (1), and the first gear (2) rotates with the motor rotor (1). The second gear (4) is mounted on the motor housing. The second gear (4) and the first gear (2) mesh, and the second gear (4) rotates under the drive of the first gear (2). Figure to be published with the abstract: Figure 1
