We Repair Pancake Servomotors!
Printed disc motors are often called "pancakes" or "pancake motors" and the name is just a catch all name for motors that have flat armature or rotor. Most are brushed DC but some AC pancakes do exist where the rotor is flattened. Several companies produce these low inertia motors but the main three are PMI / Kollmorgen, Parvex, Infranor / Mavilor.
Sometimes having an servo motor repaired is not the best option.
Extensive motor damage or unacceptable lead times, may make replacement options a more intelligent and economical choice. Servo Repair International provides various replacement options for many products. The older DC servo motors may be crossed over to newer products or other competing manufacturers. We can also provide our own direct replacement DC servo motors as replacements. Many times just a simple feedback device crossover may be needed to increase turnaround time and better performance.
