Product Description:

The VLM23D-CKNR-30 is a brushless servo motor produced by Kollmorgen for the VLM Brushless Motors series. It serves as a compact rotary actuator that converts commanded drive current into precise torque for indexing tables, packaging axes, and other mid-duty automation tasks. The motor is intended for applications that need repeatable motion in a compact housing while keeping cabling and mounting arrangements straightforward in space-limited machine layouts. That makes it suitable for equipment where precise starts, stops, and indexing cycles are required over repeated production runs.

This model uses the NEMA 23 or 60 mm metric frame class, so it can replace stepper motors or older servo units that share the same bolt circle. Its rotor is built with 3 stacks, which provide the active iron length needed for higher continuous torque without increasing the footprint. Internal copper is matched to winding code D, which suits medium bus voltages and moderate current limits. Position information is returned through a resolver, which tolerates heat and vibration well. The unit is supplied with no brake, so applications that require holding torque during power loss must rely on drive torque or an external clamp. The shaft uses mount code C, which means a plain straight shaft with a metric keyway for standard hubs.

Power conductors exit in a bundled 3 m cable, and the feedback conductors use a dedicated shielded cable with encoder leads to help reduce signal noise. At the cabinet end, the power pigtail is an unterminated shielded cable, so field-specific contacts can be added as needed. The housing drilling pattern supports a metric mounting interface, allowing the motor to seat directly against ISO flanges without adapter plates. This arrangement keeps the power and feedback wiring separated, which helps maintain signal quality during operation.
