Product Description:

The AKM23F-BNMNR-00 is a brushless synchronous servo motor produced by Kollmorgen and grouped in the AKM Synchronous Servo Motors series. Designed to work with Kollmorgen digital drives, it converts electrical command signals into precisely regulated torque and speed for compact machine stations. Applications include small gantry axes, indexing fixtures, and precision feeders where fast acceleration and accurate settling are needed for repeatable automated processes. When paired with a compatible amplifier, the motor supports closed-loop motion control during frequent starts, stops, and direction changes.

The motor has a frame dimension of 58 mm, which helps it fit in space-limited installations while using a flange that follows the NEMA bolt pattern for straightforward coupling to gearheads or direct loads. A smooth shaft eliminates keyways, so torque is transferred through clamp hubs that help minimize backlash in compact drive trains. Internally, the electromagnetic package uses 2 poles, which supports high electrical frequency and low rotor inertia for quick response. The rotor length index of 3 increases active copper length without changing the frame size, which helps raise torque capability within the same mounting envelope. This layout suits compact axes that need responsive motion without a larger motor body.

The position transducer is a Resolver configured as a single-turn inductive device, so it delivers absolute angle information within one revolution and tolerates electrical noise and high temperatures near the stator. The motor ships in a Standard configuration, so no special shaft seals, coatings, or connectors are added beyond the regular build. The stator uses winding code F, which is paired with Class F insulation in matching drive systems. The motor is supplied without brake hardware, so stopping and holding functions must be provided by the drive or external mechanics when required. This arrangement suits axes that do not need a separate holding brake at standstill.
