This is a 410 OZ/IN stepper motor with dual shafts and NEMA 34 mounting frame. These motors were used on Shopmaster Patriots, Mill Turn, Turnado and the new 2020 Bridgemill. Each motor is specially wired for the Gecko 540 drive with the DB 9 connector and special current set resistor on a 6' long cable. The shaft size is 1/2" with a flat.
These motors are a plug and play for any system using the Gecko 540 drive. For other driver systems you will need to remove the DB9 plug and wire to your machine.systems
