At Mocontronic, our passion is specializing machines to our customers’ needs. We build custom products from full-size CNC tables all the way down to circuit boards. Today, we would like to show you one of the smaller customized items we created – a shaft for an electric motor.
Some of the more simple modifications we do on motor shafts include, for example, shortening the shaft so that it fits perfectly in a specific machine. In this case, we cut a flat section out of the motor shaft, creating what is often called a “D-cut.”
D-cut motors are typically used where the load on a motor is particularly high or if the application requires directional changes. This prevents rotation, or slippage of the shaft as it turns. In this case, however, the flat-sided shaft was not flat everywhere, but rather had a flat section at the base and returned to its round shape again toward the end, making the shaft a personally tailored product for a unique application.
We started with nothing more than a hand-drawn sketch with the specifications of the flat-sided shaft; in fact, typically all we need to receive from our clients is a rough sketch with the necessary details, and then we develop a CAD drawing and machine the desired product.
With a complete CAD drawing, it was a relatively simple matter to modify this shaft with a router.
Once fabricated, the motor could be tested so that the shaft could be used as a prototype for mass-production at a later stage.
