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 servo includes a motor, an output shaft used to drive an external component and having an external lateral surface, a gear set arranged between the motor and the output shaft and used to transmit power from the motor to the output shaft. The gear set includes an output gear arranged around the output shaft. The output gear defines a through hole that allows the output shaft to pass therethrough. The through hole has an internal lateral surface facing the external lateral surface. The servo further includes a connection ring arranged around the output shaft between the external lateral surface and the internal lateral surface. The connection ring is used to connect the output gear to the output shaft when a load placed on the output shaft is less than a preset value, and disconnect the output gear from the output shaft when the load exceeds the preset value.
