AKM2G-43I-ACDNAFD0 by Kollmorgen

The AKM2G-43I-ACDNAFD0 belongs to Kollmorgen's AKM2G Magnetic Motors series and is supplied as a frameless permanent magnet servo unit for precision industrial automation. Integrated into multi-axis machines, it converts drive current into tightly regulated rotary motion so that position, velocity, and torque follow controller commands with minimal error. Its mechanical envelope and electrical characteristics suit compact installations, making the motor suitable for high-speed tool spindles, pick-and-place heads, and indexing stations in automated production cells. Because it is frameless, the unit can be integrated directly into a machine structure where space is limited and a separate motor housing is not desired.

The motor can sustain a continuous torque of 6.98 Nm at the shaft without exceeding its temperature limit, and it reaches a rated mechanical speed of 6000 rpm when the drive delivers nominal voltage and current. Each ampere supplied produces incremental torque at a rate of 0.983 Nm/Arms, while the internally generated back electromotive force is 65.9 Vrms/krpm; together, these constants affect drive selection and voltage utilization. Winding impedance is influenced by a phase resistance of 1.36 ohms, which affects copper losses during continuous duty. These electrical values help predict current demand, heat dissipation, and servo bandwidth when the motor is paired with a matched drive and feedback device.

The housing mates to machine plates through a bolt circle of 100.0 mm, and an 80 mm pilot helps keep the assembly concentric during installation. Acceleration characteristics benefit from a rotor inertia of 1.95 kg-cm², permitting rapid speed changes without excessive control effort. The winding and iron package has a thermal time constant of 27 min, so temperature rises gradually during intermittent overload periods. With a mass of 4.81 kg, the motor places only a modest static load on mounting structures and suits compact moving assemblies.
