Product Description:
The AKM31H-ACSNS-02 is a brushless servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. By converting drive current into precisely regulated torque, the unit allows machine axes and robotic joints to follow commanded motion profiles with minimal following error. Its design supports industrial automation applications such as indexing tables, pick-and-place heads, and light packaging machinery where consistent positioning and speed control are required. Electronic commutation eliminates the mechanical wear associated with brushes, while closed-loop operation allows the connected drive to correct deviations caused by changing loads. The motor can support repetitive motion cycles where rapid response and accurate control are important.
The motor has a compact mechanical envelope with a frame dimension of 70 mm. Its flange uses an IEC pattern with accuracy class N for straightforward mounting to gearheads and couplings while maintaining repeatable radial alignment. The shaft includes a keyway, so torque is transmitted through keyed hubs without relying only on friction fits. Electrical termination is handled through a special connector arrangement that differs from the standard AKM pinout and accommodates customized cable assemblies. The motor is supplied without a brake, so an external device or drive-generated torque must hold the connected load when required. Omitting internal brake components also reduces the rotating assembly’s inertial load and leaves motion-holding requirements to the surrounding machine system.
Rotor dynamics are influenced by length index 1, the shortest stack available for this frame, which lowers rotor inertia for rapid acceleration and deceleration. The electromagnetic circuit uses winding designation H, matching phase resistance and back electromotive force to drives that provide higher line voltages while maintaining moderate current. Position data is returned through a special feedback arrangement, allowing alternative sensor technology when standard resolvers or encoders are unsuitable. The feedback signal enables the servo drive to monitor rotor position and regulate torque, speed, and movement during operation. This arrangement supports applications that require a customized feedback interface while retaining the compact form and responsive behavior of the motor.
