Product Description:

The AKM73L-KK12GK-01 from the AKM series is a high-performance synchronous servo motor by Kollmorgen, which is a well-known manufacturing company of reliable motion control solutions. This type of motor has a continuous stall torque of 42 Nm, which makes it ideal for use in industries that require high levels of operation. It is also capable of maintaining 33.6 Nm of continuous torque even when the temperature rises to 60C. It also provides a high peak stall torque of 113 Nm, which is useful for tough operations. The steady-state current is 12.1 Arms and the surge current is 36.3 Arms, which shows its capability to deliver high currents for a short time.

This motor operates at various speeds with different voltages. It rotates at a speed of up to 1730 RPM with 400 VAC and 1970 RPM with 480 VAC, making it convenient when used with different systems. The rotor inertia is 0.00921 kg-m^2, ensuring that it offers fast acceleration but at the same time provides stability while in motion.

Designed for use in harsh industrial environments, the AKM73L can withstand ambient temperatures of up to 40C. It has a low thermal resistance of 0.33 C/watt and has a thermal time constant of 53 minutes. The DC resistance is 0.95 Ohms, and the static friction without the shaft seal is 0.24 Nm, making it easy to start and move the unit. The low DC resistance of the servo motor helps decrease heat losses and enhances the operational efficiency of the system. The motor operates more efficiently because reduced thermal buildup allows for greater reliability and longer equipment lifespan.
