Servomotors
Industrial servomotors and brushless motors provide ultra-precise control of position, speed and torque on your dynamic drive axes.
Paired with their dedicated servo drives, these permanent-magnet motors incorporate high-resolution resolvers or encoders, as with the Omron SmartStep, Yaskawa SGMAV, Lenze MCS or SEW CMP ranges.
Discover our selection of new, refurbished and overhauled servomotors (bearing replacement, resolver/encoder alignment) to keep your automated lines and packaging machines performing at their best.

FAQ
Unlike a standard asynchronous motor, a brushless servomotor (AC servo) has a permanent-magnet rotor and a high-precision angle measurement system (encoder or resolver). This design provides high torque at low speed, very low inertia for fast acceleration and deceleration, and positioning accuracy down to a fraction of a millimetre.
Malfunctions most often show up as bearing noise or abnormal vibration, following error or encoder communication alarms on the servo drive, excessive heating of the housing, or tripping of the phase short-circuit protection.
Yes, a complete servomotor overhaul (rewinding, replacement of high-speed bearings, realignment of the holding brake) requires specific tooling to align the phase of the position sensor (resolver or absolute/incremental encoder). Precise alignment is essential to ensure a smooth start and the axis's rated performance.
Every overhauled servomotor is coupled to its original servo drive on a test bench. We carry out a winding insulation test (megohmmeter), check the brake holding torque, verify the encoder/resolver feedback signals and run a dynamic test under load across the full speed range.
