AKM2G-43I-ACDNAFD0 Kollmorgen

Product Description:

The AKM2G-43I-ACDNAFD0 is a permanent-magnet synchronous motor built by Kollmorgen within the AKM2G Magnetic Motors series. Its role in industrial automation is to convert commanded drive current into precise rotational motion for indexing tables, packaging axes, or general-purpose servo stages. By coupling directly to gearheads or load shafts, the unit provides repeatable torque without the backlash associated with mechanical transmissions, allowing modern motion controllers to implement high-bandwidth position loops.

Under continuous operation the motor delivers 6.98 Nm at the shaft without exceeding thermal limits; this value defines the maximum static load the axis can hold. Rotor speed reaches 6000 rpm to satisfy fast pick-and-place cycles. The electromagnetic design provides a torque constant of 0.983 Nm/Arms, so each ampere of rms phase current produces predictable torque for straightforward current-loop tuning. The counter-voltage is characterized by a back-EMF constant of 65.9 Vrms/krpm, information the servo amplifier uses to reserve adequate bus voltage at high speed. Thermal loading is capped by a saturation current of 45.9 Arms, beyond which extra current yields diminishing torque gains.

For dynamic response the rotor carries an inertia of 1.95 kg-cm², enabling quick reversals while preserving positional stability. Heat stored in the stator dissipates over a 27 min thermal time constant, permitting short duty-cycle overloads before temperature approaches safe limits. Phase resistance of 1.36 Ohm and q-axis inductance of 10.2 mH set the electrical time constant that the drive’s current regulator must accommodate. The mechanical interface includes a 19.0 mm shaft, an 80.0 mm pilot, and a 100.0 mm bolt circle for direct mounting. At 4.81 kg without a brake, the housing can be attached to gantry axes with minimal added mass, while five pole pairs, low viscous damping, and 0.0380 Nm static friction support smooth low-speed tracking.
