Product Description:

The AKM21G-ENCN2-00 is a brushless servo motor built by Kollmorgen within the AKM Synchronous Servo Motors series. Designed for tightly regulated motion-control loops, it delivers precise speed and torque when paired with a digital drive in assembly cells, electronic camming stations, or lightweight gantries. Electrical commutation and integrated feedback help the controller maintain position accuracy under changing dynamic loads in automated equipment. This design is well suited to axes that need responsive starts, controlled reversals, and repeatable settling behavior during short production cycles.

The motor body uses a 58 mm frame size, so standard flanges and gearheads in that size can be mounted directly. Its stator uses the G winding, which is intended for operation with 230 VAC class drives. The motor uses two front-facing SpeedTec Ready connectors for power and signal, and the keyed plugs lock with a quarter turn for fast connection. Separate power and feedback connections help keep cable routing orderly while reducing the chance of mixing motor and signal leads. Rotor position is measured by a Comcoder that delivers 2048 lines/rev, giving the drive 8192 counts after quadrature. These feedback signals support smooth low-speed regulation and accurate tracking of commanded position changes. A short rotor stack keeps inertia low for quick acceleration, and the motor is supplied in a standard configuration with the usual materials and finish for this model.

The output uses a smooth shaft, which supports clamp or collet couplings without keyway alignment. This arrangement works well in clean coupling systems where torque is transferred through friction clamping rather than a keyed hub. Because the motor is supplied without a brake, holding torque must be provided by the drive or by external mechanical retention when power is removed. The feedback device is single-turn optical, so homing is required when absolute coordination over multiple revolutions is needed. Its EPC 15T electrical format provides index, A, and B channels for standard 5 V differential receivers.
