Abstract
A linear actuator with an integrated variable frequency drive. The linear actuator includes an AC motor. A screw assembly with an output shaft is mechanically coupled to the AC motor. An extension tube is provided with a front mount. The extension tube is configured and arranged to be driven in translatory motion in either direction by the screw assembly. A cover tube encloses the extension tube and screw assembly. An actuator housing is operatively associated with the screw assembly and the AC motor. The actuator housing has a removable cover. A bracket is attached to the inside surface of the removable cover. The VFD is mounted within the actuator housing. The VFD may be mounted on the bracket adjacent to the inside surface of the removable cover. The removable cover may facilitate heat transfer out of the actuator housing.
