Product Description:

The AKM31E-ANC2C-00 is a servo motor produced by Kollmorgen as part of the AKM Synchronous Servo Motors series. The model belongs to the AKM31 frame class. It is intended for precision positioning, speed regulation, and cyclic motion tasks in industrial automation where compact torque generation and closed-loop feedback are required. It is suited to equipment that depends on accurate starts, stops, and repeatable positioning through short motion cycles. Its compact format also fits machine axes where installation space is limited.

An integrated 24 V holding brake retains axis position when power is removed, which is useful on vertical loads or during emergency stops. Power and feedback exit through two SpeedTec Ready connectors, allowing keyed quarter-turn mating that speeds connection and helps keep cable routing orderly. Rotor position is relayed over a serial channel with 4 lines of differential signals to the drive, which helps maintain noise immunity on long cables. The feedback element is an SFD scanner, and its absolute encoder operates as a single-turn inductive device, so position is retained over one mechanical revolution without relying on optical disks. This feedback arrangement supports stable commutation data during fast-cycle operation.

The mounting interface uses an IEC flange with accuracy N, aligning the motor to gearboxes or direct-drive loads without additional centering rings. The stator has a square housing with a 70 mm frame dimension, allowing the motor to fit into compact equipment while still providing winding space for rated torque output. A smooth shaft simplifies coupling to low-backlash clamp hubs and avoids the stress concentrations found in keyed designs. This shaft arrangement is often used where accurate coupling alignment is important. The e winding code balances resistance, inductance, and back EMF for moderate continuous current with elevated peak torque capability. That winding choice helps the drive maintain predictable current response as load demand changes.
