How Servo Motors Work

The servo motor determines the movement of the CNC machine. It’s controlled with an electric signal, a pulse width modulation (PWM), which is regulated by the servo drive. The drive regulates the voltage between the motor and the control board. The motor itself is the mechanism that performs the work.

Read more about how servo drives work, and how they communicate with the servo motor.

Working Parts of a Servo Motor

The servo motor is made up of a control circuit and an AC or DC motor.

Because servo motors, and the components dependent on servo motors, must work flawlessly to create precision CNC components and parts, a faulty or broken servo can cause major problems.

Signs a Servo Motor Needs Repairs

If your CNC machine moves erratically, frequently jitters, glitches, does not move precisely, or fails to properly move in both directions, the servo motor is likely failing. A faulty servo motor puts your operations at a standstill, and you can’t afford the expense of extended downtime.

It may be difficult to determine whether your servo drive or servo motor is malfunctioning. You can be sure FANUC repair professionals at Tri Star understand the difference. We offer free technical support over the phone should you have any questions. We’ll also repair your servo drive if it isn’t working properly as well.
