Product Description:
The AKM43G-ACSN2-02 servo motor is produced by Kollmorgen for the AKM Synchronous Servo Motors series. In automated machinery, it supplies closed-loop torque and speed control so linear stages, indexing tables, and secondary packaging equipment can achieve repeatable cycle times. The design combines a low-inertia rotor, high-resolution feedback, and a standardized mounting interface. These features allow the motor to couple directly to compatible gearheads or belt drives without custom adapters, making it suitable for medium-power motion axes in assembly, electronics, and printing equipment.
Its square housing measures 84 mm across, and this frame size corresponds to IEC dimension code 84 for integration into multi-axis mounting plates. The magnetic stack has rotor length index 3, providing a balanced ratio of continuous torque to reflected inertia for servo loops with rapid acceleration profiles. Stator winding designation G matches drive outputs in the nominal voltage range used by the AKM motor family. Position feedback is generated by an optical scale that provides 2048 lines per revolution, supporting accurate position and speed measurements. The signal originates in a Comcoder assembly and is sent to the controller through complementary differential channels that help resist electrical interference. The EPC 15T code allows a compatible drive to apply the appropriate motor current parameters during system setup.
The unit has a special connector arrangement that separates the power conductors from the encoder signals and uses bayonet locking for secure cable connections. Its single-turn optical feedback is suitable for positioning tasks that return the axis to a home reference during each operating cycle. A shaft key seats in the keyway, providing positive torque transfer to a pulley, coupling, or gearhead without relying only on friction. The motor is supplied with no brake, so the drive or an external clamp must provide holding force when a static load must remain in position. Mounting uses an IEC flange with accuracy class N, supporting consistent alignment with compatible machine surfaces. The separate power and feedback paths also reduce the likelihood that motor current will interfere with the position signal during operation.
