Product Description:
The Kollmorgen AKM21E-ANCNC-00 is a compact Servo motor that is suited for applications that require controlled torque and speed. The optimized design of this motor, which strikes a balance between torque density and operating economy, makes it ideal for industrial automation processes.
The AKM21E-ANCNC-00 servo motor can take a maximum rated DC bus voltage of 160 VDC and the servo motor has a back EMF constant of 9.7 V/krpm. At its lowest operating point, the motor provides a constant current of 3.11 A, while at its highest point, the servo motor delivers 12.4 A. With a winding inductance of 5.2 mH, its line-to-line DC resistance is 3.42 Ω at 25 °C. The peak torque at stall is 1.49 N·m and the continuous torque at stall is 0.50 N·m at 100 °C. The maximum continuous power output is 0.3 kW, and the rated speed is 7000 RPM using a 160 VDC input. With a heat resistance of 1.48 °C/W, the motor can withstand mechanical speeds of up to 8000 RPM. The design includes a heat sink with a recommended dimension of 10 by 10 by ¼ inches of aluminum plate and a smooth shaft output. The rotor inertia of the motor is 0.107 kg·cm², and it weighs 0.80 kg.
The AKM21E-ANCNC-00 servo motor can withstand axial forces up to 600 N and radial forces up to 150 N. Two rotating connectors, one installed on each side of the motor, have an IP65 rating. These connectors facilitate dependable electrical interfacing and provide system designers with more flexibility. The operating safety margins under thermal load are guaranteed by the construction, which supports maximum winding temperatures commensurate with insulation classes up to 180 °C. The servo drive can only handle 0.41 HP of continuous power. This servo drive includes two rotating IP65 connectors for convenient installation.
