worm transmission mechanism is widely used in large ratio occasions.But calculating the torque is always in accordance with the situation in which the worm runs at a constant speed
and not apply to accelerating and braking situation.Particularly in the inertial load to the servo-based system
the torque of accelerating and decelerating is different from that of steady-state.The actual torque
firstly calculated by the theory
can control the system accurately
especially when the worm transmission mechanism is accelerating and decelerating in the servo-based system
