Electric Cylinder Actuator
Overview
The electric cylinder actuator is a fully enclosed actuator based on a leadscrew mechanism. When the NEMA 17 motor rotates, the motion is transferred through the mechanism and converted to linear motion by the leadscrew which causes the protruding shaft to move in and out of the front face depending on the motor rotation direction. The use of a stepper motor allows for easy plug and play with the Vention MachineMotion controller and offers complete position, speed, and acceleration control.
Applications
Electric cylinders have a wide range of applications, from pneumatic or hydraulic actuator replacement for those who do not want to run a pneumatic or hydraulic system, to high precision positioning systems.

Technical Specifications
The electric cylinders are available in 3 lengths: 100mm stroke, 250mm stroke, and 400mm stroke. All 3 actuators are powered by the same NEMA 17 motor and they all share the same lead pitch. For this reason, the data shown below is common to all three models, with the stroke length and max speed being the only variables. Each actuator also includes two pre-installed reed switches that are pre-wired to an M12 4-pin connector so that they may be connected directly to MachineMotion axis sensor inputs and act as either a home or end of travel sensor.

Assembly Instructions
The electric cylinders come with two sheet metal brackets. These brackets can be attached to Vention extrusions or plates using M8 X 16mm fasteners and T-nuts as required. The end of the electric cylinder push rod is a female M8 X 1.25 thread. It is possible to attach other Vention parts such as the Pneumatic and Electric Actuator Push Block using a M8 X 20 fastener. Once the actuator is installed, simply connect the NEMA 17 motor connector to the MachineMotion controller via the 3m connector cable to begin operation.
Note that the NEMA 17 is rated to operate at a maximum of 1.68A so the associated motor driver should be set to a limit of 1.5A to ensure motor longevity. If the MachineMotion Controller and electrical cylinder were ordered together the system will come pre-configured for you.
