Functional Features​

Low-inertia rotor for fast dynamic response.

Brushless construction reduces maintenance.

High torque density for compact automation axes.

Compatible with Kollmorgen servo drives and selected third-party amplifiers.

Application Scenarios​

CNC feed axes, robotics, indexing tables, packaging machines, semiconductor handling, material handling and high-response positioning systems.

Performance Parameters​

Smooth sinusoidal commutation with resolver, incremental encoder or absolute encoder depending on ordered feedback.

High peak-to-continuous torque ratio for acceleration duty.

Low cogging designs improve low-speed stability in selected 6SM variants.

Material And Structure​

Aluminum or cast alloy motor housing.

Rare-earth permanent-magnet rotor.

Precision bearings, keyed or smooth shaft according to suffix.

Rear feedback compartment for encoder/resolver.

Working Principle​

The servo drive supplies controlled three-phase current to the stator. The rotating magnetic field interacts with the permanent-magnet rotor. Feedback sends position and speed signals to the drive, which closes the control loop.

Installation Requirements​

Flange-mount on matched 80 mm or specified frame pattern.

Align shaft with flexible coupling to avoid radial and axial overload.

Use shielded power and feedback cables in separate cable paths.

Ground the motor frame and drive chassis.

Usage Precautions​

Verify rated torque, peak torque and thermal limits before continuous duty.

Do not exceed shaft radial and axial load ratings.

Check encoder resolution and wiring with the servo drive before startup.

Prevent condensation, excess vibration and overheating above nameplate limits.
