Product Description:

The AKM42E-EKMNC-00 servo motor is produced by Kollmorgen and belongs to the AKM Synchronous Servo Motors series. Designed for integration with digital drives, the unit supplies tightly controlled rotational output for pick-and-place heads, indexing tables, and compact conveyors. Its electromagnetic design allows high-bandwidth torque response, enabling machine controllers to execute rapid positioning routines while maintaining path accuracy. As a self-contained electromechanical actuator, it converts three-phase excitation from the drive into repeatable shaft movement that underpins closed-loop automation tasks.

The motor leaves the factory without a brake, making it suitable for axes where static holding torque is supplied by gear trains or external clamps. Position data is returned through a compact SFD resolver interface that maintains digital commutation offsets between the drive and the stator field. A square 84 mm frame simplifies mounting to IEC gearboxes while keeping overall mass low. Shaft power is delivered through an open keyway so pulleys or couplings can be locked to the shaft without additional machining. The electromagnetic circuit follows the manufacturer’s winding designation e, balancing copper loss and back-EMF for medium-voltage drives.

Controller feedback resolution is set by 4 feedback lines, allowing the drive to resolve motor position in fixed electrical intervals that match the commutation algorithm. The embedded sensor provides single-turn inductive measurement, eliminating battery-backed multiturn components and resisting magnetic interference. Its mechanical envelope adheres to the encoder’s Size 10/15/21 standard, ensuring connector and flange compatibility with common feedback cables. Finally, the rotor length index 2 stack complements the standard customization level by offering moderate inertia, giving machine builders a balance between quick acceleration and steady continuous torque without enlarging the frame.
