Product Description:
The AKM53G-BKCNAA-00 is a synchronous servo motor manufactured by Kollmorgen for the AKM Synchronous Servo Motors series. As a compact rotary actuator, it converts drive current into controlled torque and speed for positioning tasks in automated machinery and robotics. Its permanent-magnet design supports responsive motion in pick-and-place equipment, packaging machinery, and general industrial positioning systems. The motor can be paired with a compatible servo drive to regulate its position, velocity, and torque under changing loads. Its compact housing also helps conserve space around crowded machine axes.
This servo motor connects through two SpeedTec-ready connectors, which use a quarter-turn coupling system to secure the power and feedback leads while reducing installation time. Rotor position is measured by an optical scale with 2,048 lines per revolution and read by a BiSS B encoder. The single-turn optical configuration supplies absolute position within one mechanical revolution, eliminating homing cycles in short-travel axes. The flange conforms to NEMA dimensions, and the frame has a width of 108 mm, providing a rigid mounting surface for dynamic loads. This arrangement allows the motor to bolt directly to compatible gearheads and mounting surfaces without adapters. Shaft torque is transmitted through an open keyway, so couplings engage the machined key rather than relying solely on friction. Separating power and feedback connections also helps limit electrical interference while keeping cable routing compact.
The feedback hardware uses the AD34/AD58 interface family, which provides consistent pin assignments for compatible Kollmorgen drives. The motor is supplied without a brake, so vertical or overhauling loads require an external clamp or energized holding current when the axis is stationary. Its magnetic stack uses rotor length index 3, providing midrange inertia that balances acceleration with smooth operation. Winding designation G sets the resistance and inductance values required for pairing the motor with an AKD drive that has suitable current-loop parameters. The optical feedback system provides the drive with position data for closed-loop corrections during acceleration, steady movement, and deceleration. The keyed shaft provides positive mechanical engagement for applications in which repeated starts, stops, and direction changes could cause a friction-only coupling to slip.
