Worn brushes and commutator
Sparking, noise, loss of torque. Commutator skimming and brush replacement.
Armature winding fault
Rewinding or armature replacement and balancing.
Tacho or encoder fault
Speed feedback loss, jerky motion. See encoder repair.
Bearing and shaft wear
Bearing replacement and shaft repair.
Brake or gearbox problems
Holding brake and gearhead service.
Every motor is tested on our universal servo test system, India's first, covering 180+ servo brands, before it is returned. See our test equipment.
