Product Description:

The AKM24-BSM22-02 is a brushless servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. It serves as a compact rotary actuator that converts commanded current from a drive into precise torque and speed. The motor is suitable for indexing tables, packaging axes, and other automated machinery that requires accurate rotary motion.

This model can withstand an axial shaft load of 60 N, while its bearings tolerate up to 145 N of radial force, allowing direct coupling to moderate belt pulleys or gears without premature wear. A frame dimension of 58 mm keeps the motor footprint small so it fits densely packed multi-axis assemblies. The stator employs a 6-pole magnetic design that balances torque production with smooth velocity control. Inside the rotor, laminated steel and rare-earth magnets yield a low inertia of 0.000027 kg·m², permitting high acceleration with minimal drive effort. The shaft measures 9 mm in diameter and 20 mm in length to accommodate standard clamp collars. A special flange pattern simplifies mounting where conventional square flanges are impractical.

A factory-installed 24 V holding brake locks the shaft when power is removed, maintaining position on vertical or safety-critical axes. Continuous operation is permitted in environments up to 40 °C. Each watt of power loss increases the winding temperature according to a thermal resistance of 1.07 °C/W, supporting duty cycles with sustained current. Heat reaches a steady state gradually because the motor has a thermal time constant of 11 min, so brief overloads can be tolerated before protective limits engage. The motor also has viscous damping of 0.0074 N·m/kRPM, which helps the servo settle quickly without requiring excessive drive gain.
