Product Description:
The AKM41C-ANCNLB-00 is a synchronous servo motor manufactured by Kollmorgen for the AKM Synchronous Servo Motors series. It functions as a compact rotary actuator that follows commanded torque and velocity profiles in packaging, printing, and electronic assembly equipment. The model has frame size 4 and rotor length index 1, pairing neodymium magnets with low-inertia laminations to achieve quick acceleration while remaining small enough for confined machine spaces. Its permanent-magnet design supports responsive operation in applications that require frequent starts, stops, and changes in shaft speed.
The motor uses two SpeedTec Ready connectors; one handles three-phase power, while the other carries control and encoder lines. Their bayonet latches provide secure connections without requiring conventional threaded coupling rings. Position data comes from a digital EnDAT 2.1 encoder that supplies absolute values and status information to the drive. Within each revolution, the sensor provides a resolution of 16 or 32 lines per revolution. The internal counter continues beyond one turn because the device provides multi-turn inductive feedback. The motor is delivered without a brake, so any static load must be held by drive torque or an external clamp when power is removed. Separate power and feedback connections also allow the two cable routes to be organized according to the machine layout.
The motor uses a flange with IEC accuracy class N, which aligns the pilot diameter with standard gearboxes for predictable concentricity. The square housing has a frame width of 84 mm, allowing it to fit within compact machine assemblies. Output torque is transmitted through a smooth shaft, eliminating keyway stress zones and supporting the use of clamp-style couplings. The encoder head is an EQI1130/1331 type that is compatible with Kollmorgen drives capable of reading EnDAT telegrams. This encoder connection carries digital position and status data to the drive, allowing the control loop to monitor shaft movement during cyclic operation.
