Integrated universal linear actuator and manufacturing process thereof

The invention provides an integrated universal linear actuator and a manufacturing process thereof. The linear actuator comprises a hollow motor, a transmission-action module, a displacement sensor, a mechanical-electric linkage locking device and a driving control system. The hollow motor is connected with the transmission-action module through a lead screw and nut pair so that the rotating motion of the hollow motor can be directly converted into the linear reciprocating motion of the transmission-action module. The displacement sensor is connected with the transmission-action module through the mechanical-electric linkage locking device and used for outputting a position feedback signal of the transmission-action module to the driving control system. The driving control system is electrically connected with the hollow motor and used for sending a driving instruction signal to the hollow motor, controlling the hollow motor to operate and receiving the position feedback signal output by the displacement sens
