Product Description:
The AKM73Q-KKC2C-01 is a brushless servo unit manufactured by Kollmorgen within the AKM Synchronous Servo Motors series. It converts controlled current into accurately synchronized rotation for indexing tables, pick-and-place gantries, and similar automation axes. The motor integrates factory-configured mechanical and feedback components to reduce wiring complexity and simplify setup in packaging, electronic assembly, and material-handling equipment. Its design complements Kollmorgen drives that use sinusoidal commutation and high-resolution position loops, supporting smooth low-speed motion, repeatable positioning, and rapid acceleration. This arrangement is suitable for axes that must start, stop, and reverse direction without losing positional stability under changing loads.
The motor is supplied with a 24 V holding brake, allowing the load to remain locked when power is removed. Power and feedback are routed through two SpeedTec Ready connectors, a keyed plug system that supports toolless cabling. The mounting face uses a 188 mm square frame, which provides a predictable bolt pattern that matches standard IEC flanges. A factory shaft seal retains lubricant and helps protect the bearings from coolant and debris. Drive elements engage an open keyway on the output shaft for secure torque transfer. The motor uses the Q winding designation, which balances resistance and inductance for medium-voltage drives. The square housing format also helps align the motor with common machine plates and gearbox interfaces.
Position data are generated by an SFD resolver-based sensor that delivers 4 lines of digital output per electrical cycle, supplying the drive with commutation, velocity, and incremental position information. Resolver-based feedback helps the drive maintain stable commutation over a wide speed range. The sensing element is configured for single-turn inductive operation, so absolute position is retained across one revolution without mechanical gearing. Inside the feedback assembly, size code 10/15/21 indicates the physical envelope and mounting interface. The rotor length is 3, which sets the active stack height and the available inertia.
