Motor, driving device and robot

Abstract

The invention provides a motor which can be applied to the technical field of robots. The motor comprises a stator, a rotor, a speed reducer, a strain sensing assembly and a transmission shaft assembly, the rotor can rotate relative to the stator; one end of the transmission shaft assembly is connected with the rotor, and the rotor rotates to drive the transmission shaft assembly to rotate; the other end of the transmission shaft assembly is connected with the speed reducer; the speed reducer transmits load torque to the transmission shaft assembly; the strain sensing assembly is arranged on the transmission shaft assembly and used for detecting a deformation signal of the transmission shaft assembly. The invention further provides a driving device and a robot. The strain sensing assembly is designed on the transmission shaft assembly, so that the space compactness is ensured.
