NEMA34 Stepper Motor Wiring Cover

This is a plastic cover that fits on the back of a NEMA34 stepper motor to protect the wires and provide a place to mount a connector. This version has an internal wall to accomodate the back shaft of a two-shaft motor and keep the wires out of the way.

• Four (4) M4x25mm socket head cap screws
• GX16-4 Aviation Plug Connector*: https://www.amazon.com/Female-Connector-GX16-4-Silver-Aviation/dp/B07174LCGR/ref=as_li_ss_tl?s=electronics&ie=UTF8&qid=1523282089&sr=1-1&keywords=GX16-4&linkCode=sl1&tag=clll016-20&linkId=1109847e9c19003f233ca56cd215febf

The cover screws to the motor using four M4x25 socket-head cap screws. These screws fit into the back of the threaded holes for the main motor assembly screws. You may need to shorten the long screws in the motor slightly to uncover enough threads to mount the cap. Be careful not to shorten the screws too much and be sure to remove only one screw at a time so the motor castings.
