Our high-torque stepper motor has the same NEMA #23 frame as our
standard stepper motor, but it has over 75% more torque. The
increased torque means that you can increase your feed rates. It is
also better suited to handle the additional weight of the motor and
headstock on our Z-axis.
The high-torque stepper motors can also be used on any Sherline CNC
machine. The motor is 2 amps, just like our standard motors, so you
can easily upgrade your current Sherline system with the new
high-torque motors. (For example, Sherline Complete CNC systems or
P/N 8760 CNC 4-axis driver box kit.)
NOTE: Referenced upgrades apply only to Sherline products.
Shafts and Flats
Sherline stepper motors have shafts at both ends so that a
handwheel can be used for manual control if desired. Flats are
ground onto each end of the shaft to accommodate set screws for
handwheel and coupling. If a stepper motor is to be used with a
Sherline motor mount, the shaft going into the coupling should have
a flat machined or ground on it where the set screw bites into it.
If this is not done, the point of the set screw can upset the shaft
surface sufficiently to make it impossible to remove the coupling.
For non-Sherline applications, the flat may not be necessary.
Powerful dual-shaft motors are prewired for quick hookup
Stepper motors have six wire leads pre-wired in a connector that
plugs directly into the Sherline linear or rotary controller.
Both the complete CNC system and the P/N 8760 driver box come with
4 cables pre-wired with a 5-pin plug. These match the plugs on the
P/N 67127 stepper motors sold by Sherline. To hook up the system
all you do is plug each stepper motor into the cable for the proper
axis. It couldn’t get much easier than that.
