An apparatus and control system of a programmable air servo motor includes an air servo motor and an air servo motor driver, which are bi-directionally communicable with each other via communication units. The air servo motor includes an air motor, a sensor module, and a brake module that is normally locked and can be unlocked or locked by the air servo motor driver. The air servo motor driver includes a control module, an actuation module and a communication module. After actuating the air servo motor, the air servo motor driver receives torque, rotational speed and angle signals output by the sensor module. The actuation module drives the air servo motor to stop emergently, switch between forward and reverse rotation, increase or reduce rotational speed, operate at a specific angle, move by inching and operate at controlled torque similar to an electric servo motor without the need of an encoder.
