AKM2G-21D-AND2CA00 by Kollmorgen

The AKM2G-21D-AND2CA00 is manufactured by Kollmorgen for the AKM2G Magnetic Motors series. This brushless permanent-magnet servo motor is intended for closed-loop speed and position control in automated machinery, pick-and-place axes, and packaging lines. It delivers precise torque from a compact frame and connects directly to compatible Kollmorgen drives. Its design is aimed at machines that need accurate starts, stops, and speed changes without using a bulky motor package.

The motor reaches a rated speed of 8000 rpm, allowing rapid indexing where cycle time is critical. A torque constant of 0.296 Nm/Arms links phase current to torque output, which helps match the motor to a suitable amplifier. Its back electromotive-force constant of 19.5 Vrms/krpm indicates the voltage produced as speed rises. Dynamic response is supported by a rotor inertia of 0.093 kg-cm², which helps keep acceleration and deceleration behavior responsive on light loads. Mounting uses an IEC-conforming square flange that measures 58 mm, so the unit fits compact gearheads and machine brackets. The integrated holding brake operates on 24 VDC, providing power-off load retention for axes that must remain in place when the drive is disabled. Three pole pairs support electronic commutation and stable servo control, while the low static friction and viscous damping values help the controller manage low-speed motion smoothly.

Mechanical loading limits include a maximum axial thrust of 200 N and a permissible radial load of 195 N, supporting belt pulleys or pinions without placing unnecessary stress on the bearings. The housing carries an IP54 rating that helps block dust ingress and protects against splashed fluids, so the motor can be installed outside a sealed cabinet in many industrial settings. The load limits also make the motor suitable for direct-coupled mechanisms as well as compact belt-driven stages that apply moderate side forces at the shaft. Its compact body also suits installations with limited mounting space.
