We carry a few stepper motors that are sized to work well with the Gecko G540.
For machines such as a Taig or Sherline the best fit is the 166 oz-in motor. A larger motor will not improve the performance of your machine. For larger machines the 276 motor would be a better choice.
The NEMA 24 frame has the same mounting flange as the NEMA 23 but the body is a few MM larger. A few MM may not seem like much but it makes all the difference in the world. The 380oz-in NEMA 24 motor is shorter and weight less than the 276oz-in NEMA 23 and is a bit better in the acceleration department too. For you guys with the larger router tables this may be the motor you are looking for as it gets you in the power range of the NEMA 34 motors at a much lower price. These are eight wire motors so you can wire them up to fit your application. For use with a G540 wire them in parallel, with your current set to 2.8A.
Choosing the correct motor for your application can be tricky. If you have any doubts please contact us. We will help you find the best motor for your application even if it is one we don't sell.
The NEMA 23 motors come with a Molex 3.0mm MicroFit connectors attached from the factory. We have the mating connectors and pins in stock. The connector kit comes with the connector body a five pins (one extra); you will need a crimping tool to crimp the pins to the wire. We can also custom make extension cables on request.
