Product Description:
The AKM43E-ACMNR-00 is a synchronous servo motor developed by Kollmorgen for the AKM Synchronous Servo Motors series. It converts electrical power from a matched drive into tightly controlled rotation, giving automated equipment a compact means of achieving repeatable speed and position control in packaging, assembly, and material-handling stations. The motor has an 84 mm frame dimension, allowing direct mounting to gearboxes or machine walls without additional adapters.
The front face uses an IEC flange with accuracy class N, so the bolt circle and pilot tolerances match common IEC drive components. A shaft machined with a keyway provides positive torque transfer to couplings while simplifying alignment during installation. The winding uses the manufacturer’s E designation, indicating copper fill and insulation characteristics suited to moderate continuous current and rapid peak-torque delivery. The motor is supplied without a brake, which reduces its length and inertia for applications where static holding force is provided elsewhere. Drive torque can hold the rotor while the system remains energized, but an external mechanism is required when the axis must remain secured without motor power.
Rotor position data comes from a resolver mounted inside the stator housing. The sensor has 2 poles and supplies sine-cosine signals that the drive interpolates for high-bandwidth commutation and precise angular control. It supports single-turn inductive measurement, so the controller receives an absolute angle within one mechanical revolution after power-up without a battery or gear set. The resolver follows the Size 10/15/21 feedback format, which provides a consistent mechanical outline and connector arrangement for compatible AKM motors. Its inductive operating principle tolerates vibration, electrical noise, and temperature changes commonly encountered in automated machinery. The feedback signal allows the drive to regulate motor current according to rotor angle during acceleration, steady-speed operation, and controlled deceleration.
