Product Description:

The AKM23C-EFB2R-00 synchronous servo motor belongs to the AKM Synchronous Servo Motors series from Kollmorgen. Designed for closed-loop motion platforms, the unit couples with a digital drive to deliver rapid acceleration, repeatable positioning, and smooth speed regulation. By integrating a high-density stator with rare-earth magnets, the motor provides the compact torque required for pick-and-place heads, indexing tables, and small conveyor axes in automated cells.

A factory-mounted 24 V holding brake keeps the shaft locked when power is removed, so vertical or suspended loads stay in position without external clamping. Power, signal, and ground paths exit through 2 SpeedTec Ready connectors, allowing keyed, quarter-turn cabling that supports quick connection at the machine. The electromagnetic section uses winding code C, a selection that balances continuous current with moderate bus voltage for general-purpose axes. The housing cross-section measures 58 mm, which fits in tight equipment frames while still permitting a sufficient thermal path to ambient air. Rotor position feedback is generated by a Resolver, giving noise-immune sine-cosine signals that a compatible drive interpolates for velocity and commutation control.

The resolver uses 2 poles, so each electrical cycle corresponds to half a revolution. The sensor uses single-turn inductive measurement, so absolute shaft angle is captured over one revolution without batteries, while multi-turn counting is handled in the controller if required. Kollmorgen scales the resolver body to Size 10/15/21, matching the motor diameter and preserving a short axial stack length. Magnetic output is further influenced by the motor’s Rotor length index 3, which extends the active lamination stack to raise continuous torque without altering frame width. This arrangement keeps the feedback package compact while matching the motor’s small frame for space-limited axes.
