Product Description:

The AKM51E-ACCNR-00 is a Kollmorgen motor in the AKM Synchronous Servo Motors series, built to translate drive current into tightly regulated torque for indexing tables, gantry axes, and similar automation stations. It pairs electromagnetic efficiency with a compact 108 mm frame, giving machine builders a mid-size rotor that fits IEC-pattern gearboxes and couplings without extra spacers. Used with Kollmorgen servo drives, the unit supports deterministic motion profiles so equipment can reach commanded positions quickly and repeatably.

This model is supplied without a brake, so mechanical holding torque must be provided elsewhere when power is removed. Power and feedback lines terminate on 2 SpeedTec Ready connectors, allowing tool-free quarter-turn locking during assembly. Rotor position information comes from a Resolver, selected for its temperature resilience and analog commutation signals. With 2 poles of magnetic resolution, the resolver works efficiently with standard digital converters while avoiding multiple pole-pair commutation errors. The front face follows the IEC with accuracy N flange pattern so the motor centers accurately against precision gearheads. A stator outside diameter of 108 mm sets the space envelope and supports the available torque curve.

The feedback circuit is Single turn, inductive, so absolute rotor angle is maintained over one revolution without batteries or optical tracks. Output torque is transmitted through a shaft machined with a Keyway, simplifying coupling alignment in belt drives or clamp hubs. Electromagnetic depth follows Rotor Length Index 1, giving a moderate active stack that balances inertia with continuous power density. Winding designation e indicates the copper fill and turns count, tying the motor’s voltage constant to drive models engineered for 230 V nominal bus levels.
