Complete Servo Motor Repair & Servo Drive Repair in USA, Canada by Repair Servo

Our team has specialized set of skills in electronic, electrical and mechanical repair, our servo motor repair facility is designed especially for high-tech electromechanical repair, our technicians fully understand servo motors as a complete closed loop system and correctly and quickly isolate each faults and repair them successfully, we use professional tools and state of the art equipments for Servo Motor Repair and many more reasons are there to trust Ampion Industrial Servo & Controls Repair Inc. for Servo Motor Repair.

To repair any Servo Motor, it is very much important to understand the servo systems and feedback devices work in depth, servo motors could be AC or DC but they have a feedback system incorporated in each type and it is very important to know as to what type of feedback control the motor has? Feedback devices can be one or a combination of Incremental Encoders, Slotted optical or Hall Effect commutation sensors, Absolute Encoders, Sine wave output encoders, Serial Data Encoders (En-Dat, SSI, and OEM Specific codes), Serial Data Encoders with model, data, parameter and position memories, Multi Turn encoders, Resolvers and Tacho generators, electronic and electromechanical. Every feedback devices have different alignment and test equipment, specified according to manufacturer.

Every servo motor repair at Ampion Industrial Servo & Controls Repair Inc. is carried out with specialized equipment and Perfect and correct alignment of feedback devices is very crucial. At the time of Servo Motor Repair, there are so many small things to remember like Rotors should never be removed from a servo motor by hand, Pancake servo motors must be demagnetized at the time disassembly and re-magnetized upon assembly after repairs, Dragging the rotor magnets over the stator will cause damage to them as they are often very brittle/delicate, and etc so, we have designed our own jigs to align Resolvers, Encoders, Hall Effect devices commutation sensors etc to the manufacturers specifications.

Before delivering the Servo Motors to customers, we check the wave pattern of the Servo Motor winding and the torque output with the use of oscilloscopes and torque meters to ensure the Servo Motor will deliver during operation back at your business. Ampion Industrial Servo & Controls Repair Inc. test the Servo Motors both statically and dynamically to insure its proper operation and returned to you in a condition as good as the day you bought it new.

PMSM Control Techniques: FOC / Torque Control -- Motor ...

how does gearing effect output torque?

I not an engineer, i'm a computer guy...
i'm interested in computer controlled machiens, and don't know much about this, i've read on servos, and stepper motors, i understand that stuff.

The problem is, the motors that i saw are too large to fit(physically) in a place, where i need that amount of torque.

if I where to use something like a worm gear, or a small system of gears to gear down, would that increase the torque applyed at the output of the system from a lower torque motor(that is physically smaller)? and how numerically?(if they exist, i need equasions)

Yes, if you want details to a search on "mechanical advantage" and "velocity ratio" The short answer is that you can use gearing to do a straight swap between torque and speed. If you use gearing to reduce the speed by a factor of 10 you increase the torque by the same amount.

Remember that real gears will introduce a certain amount of loss due to friction etc.
