    Abstract: A brake assembly for a servo including a motor includes: a brake disk fixed to and rotatable together with the output shaft of the motor of the servo, the brake disk having a lateral wall defining at least one opening; and a linear motion actuator including a plunger and an elastic member. The plunger sides from a first position where a first end of the plunger is received in the at least one opening to a second position where the first end of the plunger is disengaged from the brake disk when the linear motion actuator is energized. The elastic member applies an elastic force to cause the plunger to slide from the second position to the first position when the linear motion actuator is deenergized so as to stop rotation of the output shaft of the motor.

    Abstract: A waist rotation structure includes a mounting disc defining a through hole, a rotatable disc located at a first side of the mounting disc, a driving device fixed to a second side of the mounting disc that is opposite the first side, and a transmission assembly. The rotatable disc defines a first cable insertion hole. The driving device includes an output shaft. The transmission assembly includes a drive gear connected to the output shaft, and a transmission cylinder extending through the through hole. The transmission cylinder includes a body that extends through the through hole, and is rotatably connected to the mounting disc and fixedly connected to the rotatable disc, and a driven gear arranged on a lateral surface of the body and engaged with the drive gear. The body defines a wiring hole extending opposite ends thereof and aligning with the first cable insertion hole.

    Abstract: A servomotor includes a control circuit, an electric motor, a harmonic drive and a sensor. The control circuit is connected to the electric motor and used to control the electric motor. The harmonic drive includes an outer casing, a wave generator, a flex spline and a circular spline. The wave generator is driven by the electric motor. The flex spline is sleeved on an exterior of the wave generator and located within the circular spline and engages with the circular spline. The flex spline is connected with an output member that is used to output power, and a post is arranged along a rotation axis of the output member. The sensor is arranged within the outer casing and used to detect an angular displacement of the post. A method for controlling the servomotor is also provided.
