Abstract

The invention relates to a modular composite motor assembly which comprises a motor stator, a motor rotor, a stator of a brake and a rotor of the brake. The stator of the brake is fixed to the end of an inner ring of a motor stator iron core, the position sensor is installed in a groove in the end of the inner ring of the motor stator, under the non-power-on condition, the rotor of the brake linearly moves in the direction away from the stator of the brake till the rotor makes contact with the outer circle of a shaft shoulder of the motor rotor and generates friction, and the self-locking shaft braking function of the motor during power failure is achieved. Under the power-on condition, the rotor of the brake linearly moves in the direction of the brake stator until pull-in, the rotor of the brake does not make contact with the shaft shoulder of the motor rotor to guarantee normal operation of the motor, the position sensor generates induction current and voltage, and the voltage signal is used for determining the position signal of the motor.

Description

technical field [0001] The invention relates to a modular composite motor assembly, in particular to a structure in which the stator and rotor assemblies of the motor, the stator and rotor assemblies of the brake, and the position sensor are respectively modularized and combined, which can be used for applications with compact space requirements Scenarios, especially in areas related to intelligent institutions such as robots and robotic arms. Background technique [0002] The traditional robot arm joints are generally composed of reducers, motors, brakes, position sensors, etc. The stand-alone machines are independent of each other, resulting in inflexible system layout, relatively single spatial structure, and relatively bloated size, making it difficult to adapt to a compact space with deep integration. required application scenarios. Therefore, the present invention proposes a rotary modular composite motor assembly. [0003] During the integration process of this stru...
