Project Description

DC Servo Motor Repair

DC servo motors are also known as brushed motors, DC brush type motors, brushed DC servo motors and DC motors. They are the earliest forms of servo motors. More and more manufacturers are doing away with their DC brush type servo motor lines in favor of the newer AC servo motors.

Brushed servo motors, are commutated mechanically and use different forms of feedback to relay speed and position. Tachometers are used for speed, resolvers and encoder for position. In some cases a combination of two or all three forms of feedback can be used. In other cases, none are used in favor of some other form of external feedback that is not integral to the motor.

Our goal is to give you the option of  that has been refurbished back to like new condition, rather than being forced into buying new. Our repair procedure follows these steps:

Servotech Repairs Pancake DC Servo Motors
& Yaskawa Cup Series DC Motors

Pancake motors are low-inertia servo motors that have very thin armatures and are incredibly challenging to work on. Kollmorgen produces a high volume of DC pancake servo motors. Servotech can also refurbish Yaskawa Cup series DC motors, unique in and of themselves, but low inertia just like pancakes. Read more on our pancake servo motor repairs.
