Product Description:

The AKM11B-ANY22-00 is a synchronous servo motor manufactured by Kollmorgen as part of the AKM Synchronous Servo Motors series. It is designed for closed-loop positioning in industrial automation, where consistent torque and rapid response are needed for packaging machinery, semiconductor handlers, and light pick-and-place axes. In these applications, the motor converts drive commands into controlled rotary motion so short cycles can be repeated with stable speed regulation. The motor’s construction matches the series approach of small frame sizes paired with high dynamic capability, and it provides a standardized drive element that mates directly to Kollmorgen digital amplifiers and common IEC gearheads.

The mechanical side of the unit centers on a 40 mm square frame that minimizes the overall envelope while allowing sufficient winding volume for the B winding designation. A flange drilled to IEC accuracy N simplifies alignment to metric gearboxes and reduces the need for shimming during assembly. Power and feedback conductors exit through a single y-tec connector, and this consolidated plug helps simplify cable routing and reduce the chance of reversed mating. Output torque is delivered through a smooth shaft, which avoids keyway stress concentrations in low-load couplings. Load holding during downtime is provided by a 24 V holding brake that clamps the rotor when the drive is disabled. The compact frame is useful where adjacent axes are mounted close together or where available machine space is limited. A rotor length index of 1 and the standard customization level keep the mechanical layout consistent across multiple machine platforms.

For servo loop closure, the motor uses an optical encoder with 2048 lines per revolution that feeds incremental and commutation signals to the drive. This sensing element is a Comcoder assembly identified by feedback type EPC 15T, delivering digital channels with low phase jitter. The encoder channels allow the amplifier to monitor rotor position and commutation in real time during acceleration, indexing, and settling. Position data are absolute across one mechanical turn thanks to the single-turn optical track, eliminating the need for homing routines at power-up. The matched winding supports accurate velocity and torque control in small-format automation equipment.
