Product Description:
The AKM41H-ACCNC-00 is a synchronous servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. The unit delivers closed-loop shaft torque and speed under the control of a matched digital drive, enabling accurate positioning on compact packaging stations, pick-and-place axes, and light machining spindles. Its IEC-pattern mounting flange allows direct attachment to gear reducers or machine frames, making the motor suitable for a wide range of industrial automation tasks.
The motor is supplied without a brake, so any holding function must be managed by the drive or an external clamp. Power and feedback are routed through two SpeedTec-ready connectors, which use bayonet locking to reduce cabling time during installation. The square frame measures 84 mm and matches an IEC flange with accuracy class N, supporting repeatable alignment with shafts and housings. The internal copper uses the H winding code, which indicates the resistance and inductance values needed to pair this rotor length 1 model with a drive that supplies the correct current and voltage. The standard customization level means the mechanical tolerances and coatings follow the baseline requirements for the AKM series. This arrangement keeps the power and feedback connections accessible while preserving the motor’s compact mounting profile.
The SFD sensor provides 4 lines of incremental information per electrical cycle, while the absolute channel uses the SFD protocol to communicate revolution and commutation data. Its single-turn inductive design requires no batteries and resists magnetic interference during operation. The encoder body conforms to Size 10/15/21 dimensions, allowing it to fit standard resolver housings without adding unnecessary axial length. Motion is transmitted through a shaft with a keyway, providing positive torque engagement with couplings or pulleys and maintaining alignment during rapid reversals. The feedback arrangement gives the connected drive the rotor information needed for electronic commutation and closed-loop motion control. The keyed shaft also helps prevent coupling slippage when the motor repeatedly accelerates, decelerates, or changes direction under load.
