Product Description:
The AKM21G-ANMNAD-00 is a brushless synchronous servo motor engineered by Kollmorgen within the AKM Synchronous Servo Motors series. As a compact rotary actuator, it converts drive current from a digital amplifier into controlled torque and speed for packaging, pick-and-place, and light assembly axes. Closed-loop drive control allows the motor to respond rapidly to position and velocity commands while compensating for changes in the connected load. Its compact form is suitable for industrial machinery with restricted mounting space. The motor can be used with appropriately matched digital servo drives in applications that require accurate, repeatable rotary motion.
The motor housing has a frame dimension of 58 mm, providing a compact square face for connection to small gearboxes, pulleys, or other driven components. An IEC flange with accuracy grade N is machined into the front face, providing a standardized mounting interface that reduces the need for custom adapters. The accuracy grade helps maintain alignment and concentricity between the motor shaft and the connected equipment. The output end has a smooth shaft, so torque is transferred through a clamp coupling or compression hub rather than a keyed connection. This shaft arrangement can reduce mechanical play when it is paired with a properly fitted coupling. The electromagnetic stack uses winding code G, which provides the electrical characteristics required for matching the motor to a compatible drive. The selected drive must supply the voltage and current needed for stable torque production throughout the intended speed range.
This motor is supplied without a brake, so an external clamp or another mechanical holding device is required if the load must remain stationary after power is removed. Its electromagnetic core has rotor length index 1, representing the shortest magnetic stack available for this frame size. The shorter rotor helps keep rotational inertia low, supporting rapid acceleration and deceleration in high-cycle machinery. The motor belongs to the second-generation AKM platform, which is intended for dynamic servo applications with limited installation space. Its brushless design avoids the wear associated with mechanical commutation and supports consistent operation during repetitive motion. Temperature sensing and motor phasing must be connected according to the requirements of the selected drive and cable arrangement.
