Product Description:

The AKM2G series AC motor AKM2G-31D-ANDNCA00 is built by Kollmorgen. It has a low moment of inertia 0.0000426 kgxm^2 to achieve full control during high-speed operations. The motor possesses a light weight rotor that turns at a continuous speed of 3500 r/minute at 240 VAC and its peak mechanical speed goes up to 8000 r/minute.

The AKM2G-31D-ANDNCA00 motor features a back emf of 54.4 V/krpm and provides a peak turning effect of 6 Nm. Its torque constant is observed as 0.836 Nm/Arms and at normal load conditions when the motor is operating on 480 V AC, its power utilization is 1.13 kW. At that scenario the torque produce is 1.46 Nm and the rotational speed reaches up to 7300 r/minute. The AKM2G-31D motor contains a resolver feedback system for position and speed control. Its thermal resistance is 0.980 K/W and the dynamic load rated power is 594 W. This motor has an IEC flange type and its internal inductance occurs through 4 pairs of poles for steady torque generation. PT-1000 thermal sensors are used for monitoring temperature value in real time to protect the motor from overheating. Its static friction value is 0.01 Nm and it take 1020 sec as thermal time constant to stabilize in temperature. The AKM2G-31D motor uses 10 x 10 x 1/4 inches aluminum heatsink to dissipate heat through natural convection and radiation.

The AKM2G-31D-ANDNCA00 motor has an impedance value of 10.9 Ohm and the stator inductance measures 24.2 mH. It has a smooth design of shaft with an optional oil seal to make the motor an overall IP65 protected from particles greater than 1 mm. The AKM2G-31D motor weighs 4 lb. without a holding brake and its damping coefficient is 0.0039 Nm/krpm.
