Product Description:

The AKM44G-ACCNAA-00 servo motor is produced by Kollmorgen as part of the AKM Synchronous Servo Motors series. This brushless unit serves as a compact actuator for coordinated motion in packaging lines, pick-and-place arms, and other industrial automation axes that demand accurate velocity and position control. Its mid-size frame, digital feedback, and low-inertia construction support responsive moves while conserving cabinet space on the machine. The brushless design also avoids contact-based commutation parts, which helps maintain consistent performance during repetitive duty cycles.

The motor’s power and signal leads are routed through 2 SpeedTec Ready connectors that lock with a quarter-turn for quicker connection. Position data comes from a BiSS B encoder that delivers absolute feedback at 2048 lines/rev, giving the drive fine resolution for tight servo loops. Interface optics marked AD34/AD58 support this channel, and the encoder operates in single-turn mode, so it does not rely on a battery to preserve multi-turn data. An IEC flange with accuracy grade N fits standard gearheads without shims, while the square housing width of 84 mm places the motor in the size-4 frame group of the AKM family.

The active magnetic stack uses index 4, increasing continuous torque compared with shorter rotors of the same diameter. A G winding matches the voltage and current profile expected by Kollmorgen AKD and S series drives. Output torque is transmitted by a shaft with a keyway for positive mechanical engagement with pulleys or rigid couplings. The assembly ships without a holding brake, so static load retention must be supplied by the drive or an external lock. This arrangement is suitable where the axis already uses drive-applied holding torque or separate mechanical restraint.
