Kollmorgen LE06565-AG
Product Name: LE Iron-Core Direct-Drive Linear Servo Motor (Forcer Segment)
Product Overview:
A 3-phase U-channel iron-core linear motor from the Kollmorgen LE series. It produces linear thrust directly from electrical current without ballscrew, rack or belt. “LE06565-AG” denotes a specific forcer length, stack and connector layout; the magnet track is ordered separately.

Construction & Materials:
Laminated silicon-steel teeth, epoxy-potted copper coils, aluminum alloy housing, rare-earth NdFeB magnet track (separate part), stainless non-magnetic side plates, integral linear encoder scale optional.
Working Principle:
A traveling magnetic field synthesized by the servo drive interacts with the permanent-magnet track via Lorentz force; net force is F = Kt × Iq. Position loop closes through external linear encoder (1 Vpp sin/cos, EnDat or BiSS). No mechanical conversion loss.
Features:
Zero backlash, high stiffness, sub-micron repeatability achievable with fine encoder, cogging cancelled by skewed laminations, high thrust density per footprint.
Applications: Semiconductor die bonders, optical inspection XY stages, precision pick-and-place, lab automation, laser cutting gantries.
Installation & Notes:
Air gap 0.6–1.0 mm between forcer and magnet track, alignment tolerance ±0.1 mm over travel. Magnet track must be non-ferrous shielded to avoid attracting chips. Separate power and encoder cables by ≥ 100 mm. Never energize without encoder feedback—runaway risk.
