Product Description:
The AKM31C-ACCNEF-00 is a brushless servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. This compact rotary unit delivers precise torque and position control for indexing tables, gantry axes, and packaging stations where closed-loop speed stability is required. When paired with a compatible digital drive, the motor converts electrical commands into repeatable mechanical motion, allowing automated equipment to accelerate, decelerate, and hold position in coordination with sensors and programmable logic controllers. Its brushless design supports responsive operation without the mechanical commutation components found in conventional brushed motors.
The motor housing has a 70 mm frame dimension, so it fits machinery that uses compatible IEC mounting patterns without requiring adapters. Power and feedback are routed through two SpeedTec-ready connectors; these bayonet-style plugs shorten installation time and maintain shielding continuity for encoder signals. A front-face IEC flange with accuracy N controls axial runout, supporting applications where concentricity affects gear or pulley life. Output torque is transferred through a shaft with a keyway, providing positive mechanical engagement with couplings or belt wheels. The stator uses a C winding, which establishes the copper fill, resistance, and inductance values needed for the drive to supply matched current at the intended bus voltage and switching frequency. The compact housing and standardized mechanical interface allow the motor to be installed in space-limited machine assemblies while maintaining accurate alignment with the driven load.
The motor is supplied without a brake, which reduces its length and inertia in systems that rely on drive torque or external clamps for holding duty. A rotor length index of 1 sets the magnetic stack depth, balancing continuous torque with thermal dissipation inside compact enclosures. Because no internal brake secures the shaft after power is removed, vertical or gravity-loaded axes require an external holding mechanism when stationary. The keyed shaft provides a secure connection for transmitting torque, while the connector arrangement keeps power and feedback wiring organized at the motor housing. These features support controlled acceleration and positioning in applications that require a compact motor with a direct mechanical connection to the load.
