Product Description:
The AKM43L-EKMNR-00 servo motor is manufactured by Kollmorgen and belongs to the AKM Synchronous Servo Motors series. As a brushless synchronous machine, it converts current from a matched drive amplifier into regulated torque and speed, allowing precise axis positioning in packaging lines, pick-and-place gantries, and other automated equipment. The motor’s electromagnetic design supports rapid acceleration and deceleration, enabling control systems to execute fast movements while maintaining repeatable positioning under changing loads. Electronic commutation eliminates the mechanical brushes used in conventional DC motors, reducing wear during repetitive industrial operation.
Its square frame measures 84 mm across, enabling installation in compact machine layouts while accommodating the magnetic stack associated with rotor length index 3. The L winding provides electrical characteristics suited to moderate bus voltages and continuous-duty operation with a compatible servo drive. A feedback arrangement with 2 poles provides one electrical cycle for each mechanical revolution, supporting rotor angle detection and motor commutation. Position is sensed by a resolver, which supplies analog sine and cosine signals that remain stable under temperature changes, vibration, and electrical noise. The drive processes these signals to regulate shaft position and velocity throughout the motor’s operating range.
Because the motor is supplied without a brake, static holding torque must be provided by the drive or external locking hardware when the axis is stationary. The sensing element is a single-turn inductive device that reports shaft position within one complete mechanical revolution without battery-backed memory. Its resolver housing follows the Size 10/15/21 format, providing the corresponding mounting dimensions for the feedback assembly. The output shaft has an open keyway, allowing positive torque transfer to a pulley, gearbox, or rigid coupling. Proper alignment of the keyed connection helps limit uneven loading on the shaft and bearings during acceleration. The motor uses the standard configuration associated with this model code, without a special brake or alternate feedback arrangement.
