Frequently Asked Questions

Q. How do I send repairs to Amptron?

A. Fill out a Free Evaluation/Quote form first, it's right on this website ( Free Evaluation/ Quote Form) and submit it. Upon receipt we will send you an RMA (Return Material Authorization) Number. Carefully pack and ship the servo motors / Control devices it to us with as much information as possible including symptoms of failure and any other information relating to the failure of the unit/device. (Electronic devices/Servos are very delicate. Please use care when packaging your servo/device. Many motors/devices arrive at our facility with shipping damage that either increases the cost of repair or renders the device/servo non-repairable). Upon receipt by us, your item will still be logged in our system and the free evaluation/ repair process will begin.

Q. Do Amptron repair Servo Motors/ Electronics Controls regardless of manufacturer?
A. More likely we will be able to repair the Servo Motor/ Electronics Control Unit for you – no matter who the manufacturer is. However, especially the servo motors must not have been tempered with or disassembled in any way.

Q. How long will it take to get my item repaired and back to me?
A. Our normal repair service includes Free Evaluation and a quote in approximately 24 hours after we receive your unit. The evaluation comes at no risk to you; all you pay is shipping. Once we receive your approval, the repair will typically be completed in 5 to 14 working days depending on parts availability and workload. Return shipping will depend on how far and how fast - usually from 2 to 4 days UPS ground in North America. Of course, overnight shipping is available as well to most locations. In addition, customers can use our RUSH or PRIORITY repair services.

Q. How much will it cost to repair?
A. You will receive a free quote after we evaluate your item. By providing job-specific pricing we can offer you, our customer, the best pricing. Most repairs can be completed for less than 30% to 50% of the cost to buy a new item.

Q. What are Standard , Priority and Rush turnaround times?

  • Standard turnaround time: 5-14 working days after approval pending parts availability.
  • Priority turnaround time: within 3 – 5 working days pending parts availability (customer approval is deemed obtained)
  • Rush turnaround time: within 3 to 48 hours or less pending parts availability (customer approval is deemed obtained)

Q. What is the Free Evaluation Process?
A. Our repair technicians at Amptron carefully review each servo motor/ electronics control device/item sent to us for a free evaluation. We will look for obvious signs of damage as well as known common faults for that particular device/item, and for signs of previous repair attempts. We will test the functionality of some suspect parts and look for signs of catastrophic failure that would make the unit irreparable. At this stage, we will not do a complete component by component test. Our repair prices are based on the amount of damage to the items.

Q.  How much will it cost to repair?
A. You will receive a free quote after we evaluate your item; we do not charge for bench time for this. By providing job-specific pricing we can offer you, our customer, the best pricing. Most repairs can be completed for less than 30% to 50% of the cost to buy a new item.

Q. How will you test the servo motor I send you?
A. Every servo 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. Servo 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 servo motors are run-in for 24 hours (except emergency rebuilds).
