Servo FAQ

Do you repair servos manufactured by "XXX"?

More than likely we will be able to repair your servo for you - no matter who manufactured the motor. Since 1982 we have repaired servos from hundreds of manufacturers from around the world. We've developed a proprietary process that allows us to quickly reverse engineer complex servo motors, stepper motors, spindle motors, and feedback devices. However, these motors must be intact - not tampered with or disassembled in any way! Parts availability can be a problem. However, we have an extensive parts database complete with international contacts that typically allow us to locate all parts necessary for repair.

How does your normal repair service work?

Simply call for an RMA (Return Materials Authorization) number, and ship your motor to us with the RMA number and as much information as possible including,company name, contact, symptoms of failure and any other information relating to the failure of the motor. (For your convenience, we have an on-line "Shipping Form" you may complete and either email to our facility or print a copy to ship with your motor.)

Approximately three working days after we receive the motor, we will fax you a quote. Repair is typically completed within 7 to 10 working days after your approval. Parts availability can be a problem and turnaround time can be delayed. However, we have an extensive parts database complete with international contacts that typically allows us to locate all parts necessary. If a faster turnaround time is needed, we offer an expedite service that typically reduces turnaround time to 24 to 48 hours in-house. In some cases, repair is accomplished and the motor shipped the same day it is received.

How quickly can you repair my motor?

We offer an expedite service that typically limits turnaround time to 24 to 48 hours in-house. Our focus is on resolving your servo problem as quickly as possible. Call our technical support personnel for assistance in analyzing your failure.

What is A-1 Servo's Warranty?

Our warranty is simple: Every device we rebuild has a minimum 90-day warranty that covers parts and workmanship. However, we understand that a motor may sit on your shelf unused (as a spare) for longer than 90 days. Consequently, our warranty time is based more upon our evaluation of the motor and its condition rather than the exact date the rebuild was completed. Our objective is to be fair. This statement in no way modifies or changes in any way our official warranty. Our official warranty is available upon request.

How will you test the servo I send you?

Every device is tested both statically and dynamically to insure proper operation. Encoders, resolvers and tachometers are adjusted to the correct timing, waveform shape, offset position, voltage level, etc. Every effort is made to reduce stray electrical noise to the lowest possible level, if not eliminate it completely.

Electrical parts are tested for high voltage leaks, shorts, grounds and overall physical condition. Motors are tested for vibration, current draw, back EMF, torque, temperature rise, shaft runout, keyway condition, balance, acceleration rate, magnetic field strength, magnet position and mechanical integrity, brush spring pressure, correct brush compound, etc. On low inertia motors, start/stop ramps are tested to verify acceleration capabilities. Completed motors are run-in for 24 hours (except emergency rebuilds).
