Are servo motors repairable?
Servo motor repair is claimed by many but mastered by few! There are many steps involved in repairing servo motors; the trickiest step is in the feedback repair and realignment. This is how we can accurately repair, realign and fully load test your servo motors for a perfect repair every time!
Why do servos fail?
Foreign debris in your servo motor can cause many of the same issues as moisture and accelerate the motor’s deterioration. Additionally, build ups of dirt can block or jam parts—in particular fans, which can then lead to overheating, another leading cause of servo motor failure mentioned above.
What is inside the servo drive?
A servo motor is part of a servo mechanism consisting of three key elements – a motor, a feedback device, and control electronics. The motor can be AC or DC, brushed or brushless, rotary or linear, and of any size.
How does a servo drive work?
Function. A servo drive receives a command signal from a control system, amplifies the signal, and transmits electric current to a servo motor in order to produce motion proportional to the command signal. Typically, the command signal represents a desired velocity, but can also represent a desired torque or position.
How do I know if my servo motor is broken?
When the gear fails (broken tooth, hard point, etc.), the servo may get stuck, free moving or any combination. When the motor breaks (usually the brushes inside the DC motor are the culprit), the servo stops working altogether (as if it was unplugged) or overheats and burns.
How do you tell if a servo is broken?
How do you troubleshoot a servo?
Make sure to clean or remove particles, dry out any plugs and check all cables. Check for a bind in the axis or if the brushes are worn down in the DC motor. Use a volt ohm meter to check for an incoming power supply. You’ll mainly want to test the servo drive to ensure the voltage is correct.
