Product Description:

Kollmorgen’s AKM23D-EFB2C-00 belongs to the AKM Synchronous Servo Motors series and is intended for closed-loop motion axes that require compact torque delivery and accurate positioning. As an AC servo unit, it installs directly into packaging, assembly, or semiconductor tools where its response characteristics allow tight velocity and position control through a paired drive controller. The motor is supplied in the Standard customization level, indicating that no special shaft seals, coatings, or windings have been altered from the baseline configuration. Its compact format suits equipment that needs responsive motion without a large motor envelope.

The motor’s braking element is a 24 V holding brake; this electromechanical clamp secures the shaft whenever the drive is disabled, preventing drift on vertical loads. Power and feedback cables are routed through two SpeedTec Ready connectors, a quick-lock interface that simplifies wiring and supports fast connection during installation. The stator outer size measures 58 mm, so the unit fits into small mechanical envelopes without additional adapter plates. Mechanical output capability is influenced by rotor length index 3, which balances inertia with peak acceleration for compact servo axes. Electromagnetic behavior follows winding designation D, a coil pattern selected for applications that run on higher bus voltages while favoring lower phase current.

Shaft angle feedback is provided by the compact SFD resolver, an inductive sensor that integrates commutation data and position feedback in a single housing. Its measurement span is single-turn inductive, supplying one mechanical revolution of position information and supporting applications that do not require multi-turn feedback. Signal resolution is determined by four data channels, and the physical dimensions match Kollmorgen’s encoder envelope coded as Size 10 / 15 / 21. This format suits compact servo installations with limited available space.
