This motor plate is designed to accept a size 17 stepper motor and is supplied with the fixing screws and nuts to attach to the Q-module end. With the screws and nuts the plate can be spaced the correct distance (usually around 30 mm) to accept a motor coupling. The plate is made of 7 mm black delrin. Pleas note no screws are supplied for attaching the stepper motor on, as the length and type will depend on the particular stepper motor.
