Product Description:
The AKM22G-ENMNEM-00 is a brushless synchronous servo motor built by Kollmorgen for the AKM Synchronous Servo Motors series. The motor converts electrical input from a matched drive into regulated mechanical rotation for positioning axes, conveyor sections, or small gantries in industrial automation. Its 58 mm square frame permits direct mounting in compact machinery, while the smooth shaft simplifies coupling to gearheads or pulleys. The compact housing is suitable for motion systems where installation space is limited.
At stall, the motor can supply 0.88 N-m of continuous torque while drawing 4.85 A rms; this pairing establishes the thermal limit for indefinite holding or low-speed movement. For short acceleration bursts, the stator supports 2.79 N-m of torque and up to 19.3 A rms of current, which helps with drive sizing for rapid indexing cycles. A torque constant of 0.18 N-m/A rms links commanded current to output torque, simplifying control-loop tuning. Six magnetic poles work with winding designation G to deliver the required performance, and a DC phase resistance of 1.77 ohms influences electrical losses during sustained operation. The motor is supplied without a brake, so an external holding method may be needed when a stationary load cannot be maintained by drive torque. Power and feedback signals pass through dual Molex connectors with IP20 protection.
The back electromotive force constant is 11.7 V rms/kRPM, so the drive receives approximately 11.7 V per thousand revolutions for voltage-based speed estimation. A winding inductance of 3.19 mH affects current rise time and the bandwidth available for high-frequency control commands. The low rotor inertia of 0.0000161 kg-m² supports fast acceleration while maintaining a stable response with light loads. Position feedback is obtained from a commutating encoder that provides 4096 lines per revolution, yielding fine incremental resolution for servo control loops. The IP54 enclosure resists dust and splashing water in industrial environments. Rotor length index 2 establishes a magnetic stack depth that balances torque capability with the motor’s overall length.
