About the Sherline Stepper Motors...
Sherline offers machines in CNC-ready configuration for those wishing to supply their own stepper motors and controls. We also offer linear and rotary motion controllers that will drive an individual stepper motor without the need for a separate computer or driver. Sherline motion contollers come with stepper motors, but for those who wish to purchase additional motors or wish to buy them from us to put together their own CNC system, we offer a high quality stepper motor in two versions.
The basic specs are noted below. More detailed manufacturer specifications can be found by following the link near the bottom of this page.
Frame size: NEMA #23
Shaft: 1/4" diameter, dual shafts
Torque: 120 oz. in.
Voltage: 3.2 V.
Current: 2 A
Step Angle: 1.8° (200 steps/rev)
Shafts and flats...Sherline stepper motors have shafts at both ends so that a handwheel can be used for manual control if desired. 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 sufficiently to make it impossible to remove it from the coupling. For non-Sherline applications, the flat may not be necessary.
End Connector or raw leads...
Stepper motors have six wire leads with a pre-wired 5-pin connector that plugs directly into the Sherline linear or rotary controller. Below are two diagrams showing the colors of the leads as they connect to the pins on the connector on both the older SKC and the current NMB stepper motors. The motors can also be purchased without the 5-pin connector for use in non-Sherline applications.
Figure 2—67127 Stepper motor connection colors as seen from BACK side of connector where leads are soldered on. This is how the six wires are soldered to the Sherline 5-pin connectors. (NOTE: SKC refers to the Shinano Kenshi motors sold prior to 3/04. NMB refers to the brand of stepper motors sold after 3/04.)
