High-Torque Stepper Motor
Sherline’s high-torque stepper motor features the same NEMA 23 frame size as our standard stepper motor but delivers over 75% more torque - ideal for increased cutting feed rates and better performance on the Z-axis, where it can handle the added weight of the motor and headstock. Note that maximum rapid feed rate remains unchanged.
Important Compatibility Note: Due to the increased torque, these motors require an updated CNC coupler (P/N 671052, sold separately). If upgrading from systems using the discontinued coupler (P/N 67105), ensure you purchase the correct replacement.
Rated at 2 amps, these motors are fully compatible with all Sherline CNC machines, including complete CNC systems, our 4-axis driver box, CNC rotary tables and our linear and rotary motion controllers. No additional power supply upgrades are needed.
Dual-shaft design allows handwheel operation for manual control. Flats are precision-ground on both ends to secure handwheels and couplers via set screws. When used with Sherline motor mounts, the shaft end engaging the coupler must have a flat to prevent damage from the set screw. This may not be necessary in non-Sherline applications.
Each motor includes a six-lead cable with a 5-pin connector, pre-wired to interface seamlessly with Sherline's CNC equipment, making setup fast and easy - just plug in and go.
Stepper Motor
Sherline stepper motors feature shafts at both ends, allowing for manual control via a handwheel, if desired. Flats are ground onto each shaft to accommodate set screws for the handwheel and coupling. For use with a Sherline motor mount, ensure that the shaft entering the coupling has a flat machined or ground onto it where the set screw secures it. Failure to do so may damage the shaft, making the coupling difficult to remove. For non-Sherline applications, the flat may not be necessary.
Powerful Dual-Shaft Motors
-
P/N 67127: This motor comes pre-wired with six leads in a connector that plugs directly into Sherline's linear or rotary controllers. Both our CNC system and driver box include four pre-wired cables with 5-pin plugs that match the P/N 67127 stepper motor. Simply plug each stepper motor into the corresponding axis cable for an easy setup.
-
P/N 67130: This motor features six raw wire leads, and does not include a connector, so that it can be used with non-Sherline controllers that have a different pin configuration.
Note: Due to the lack of standardization in the industry, wire colors can vary between suppliers. If using a connector not supplied by Sherline we recommend using a continuity checker to identify which wire connects to each pin on the DIN plug. Typically, the black and white (or tan) wires are connected to the center pins, but other colors may vary. See our specifications sheet for wiring diagram.
