Product Description:

The AKM51G-ACCNR-00 is a synchronous servo motor manufactured by Kollmorgen within the AKM Synchronous Servo Motors series. As a torque-generating component, it couples directly to machinery that requires closed-loop speed and position control. It supplies precise rotary motion for packaging stations, pick-and-place axes, and metering pumps, where stable response and repeatable movement are needed during frequent start-stop cycles. It is intended for servo systems in which the drive continuously corrects speed and position errors as load conditions change.

This unit is delivered without a brake, so load holding must be handled by the drive or an external locking device whenever the axis is stopped. Two field-installable 2 SpeedTec Ready connectors separate power and feedback wiring, which keeps cable routing organized and reduces the chance of mixing the two interfaces during installation. The stator housing uses a 108 mm frame, which sets the mounting footprint and provides thermal mass for heat dissipation during continuous operation. A rear-mounted Resolver provides rotor position feedback with strong immunity to electrical noise, and its 2 poles support the commutation process used by the servo drive. The motor uses the standard build level, rotor length index 1, and Size 10/15/21 resolver hardware.

Position data is produced by a Single-turn inductive feedback channel, which avoids multi-turn counting electronics in systems that use homing cycles at startup. The mounting face uses an IEC accuracy N flange, helping keep alignment consistent for gearheads or precision couplings and supporting accurate shaft centering at the machine interface. Mechanical power is transferred through a keyway shaft that helps prevent hub slip during repeated starts and stops. Electromagnetic behavior is matched by winding G, which selects a voltage-to-current balance suitable for the motor's intended drive pairing. This arrangement works well in equipment that references the axis during startup and then runs repeated motion cycles through a direct mechanical connection.
