Among the various accessories of the CNC router machine, the drive motor is the key factor. Choosing the right motor is critical for the efficiency and productivity of your motion control applications. So how to choose the right motor for the cnc router machine? Start by understanding how these motors differ and the specific pros and cons each offers. You can then align the capabilities of the motor with the needs of your application.

 

Stepper motors generally provide the most value on small-footprint machines not in need of high speeds or torque. Stepper motors are capable of generating high torque at zero speed, but torque tends to decrease as speed increases. And speed limitations are commonplace with stepper motors, which generally operate most effectively at 1,200 RPM or lower. From a high-level view, stepper motors can serve as a compact and economical solution that is dependable for small-machine applications.

 

Once a CNC machine reaches a certain size and speed, it begins to require more power to work effectively. This is where servo motors come into play. Servos are best for applications that require improved positioning precision and resolution. They run faster than stepper motors (usually at several thousand RPMs) and also provide more consistent torque across the entire speed range of the machine.

In many of our CNC Router machines, we use Taiwan Delta servo motors and Japanese Yaskawa servo motors, which are also used by many of the finest machine tool builders in the world. It has resonance suppression function to ensure that the machine runs smoothly at high speed.
