Product Description:

The AKM42E-ACC2AB00 is a servo motor produced by Kollmorgen as part of the AKM Synchronous Servo Motors series. Designed for closed-loop positioning in automated assembly stations, pick-and-place axes, and packaging machinery, the unit converts drive current from a digital servo amplifier into controlled torque and speed with high dynamic response. Its compact frame supports direct integration into mechanical modules where repeatable motion, stable feedback, and accurate axis control are required during frequent starts, stops, and direction changes. In this type of application, the motor works with the amplifier’s feedback loop to correct load disturbances and maintain consistent motion during indexing, transfer, and placement tasks.

Mechanical and electrical interfaces are arranged for straightforward installation and reliable feedback handling. An integrated 24 V holding brake secures vertical loads when power is removed, while two SpeedTec Ready connectors allow tool-free cable connection and support clean routing in compact machine spaces. Position data comes from a 2048 lines per revolution incremental track within the BiSS B encoder, giving the drive fine feedback resolution for smooth velocity control and stable response at changing speeds. The stator fits inside an 84 mm square frame that suits compact layouts, and this version uses the standard customization level rather than a special build.

The encoder section also provides optical multi-turn feedback, so absolute position is retained across multiple revolutions without battery backup. Mounting uses an IEC flange with accuracy class N to support concentric alignment with couplings and gearboxes during face mounting. The motor uses a keyway shaft for positive torque transmission, and winding code e matches the electrical characteristics intended for general-purpose duty cycles. Interface logic is compatible with AD34 and AD58 feedback formats, and rotor length index 2 provides a moderate stack height that helps balance torque output with low inertia for responsive acceleration.
