High-Efficiency Laminated Rotor Core with Ceramic Shaft – Low-Loss
Silicon-Steel Stack for BLDC Pumps & Fan Motors | Custom OD 20-60
mm
Product Description:
Our rotor-core assemblies combine low-loss NGO silicon-steel laminations with a precision ground ceramic shaft to deliver minimal
eddy-current loss and whisper-quiet rotation in compact BLDC and
shaded-pole motors. The tightly welded lamination stack preserves
magnetic integrity, while the non-conductive shaft eliminates stray
currents and galvanic corrosion—ideal for wet-running pump
environments and medical devices. Each core is dynamically balanced
to G2.5 and cleaned in ultrasonic baths to ensure zero debris before
magnet over-moulding.
Features:
High magnetic efficiency – ≤1.5 W/kg core loss at 50 Hz for cooler, longer-life motors.
Ceramic shaft option – outstanding wear resistance in water or chemical media.
Vacuum-impregnated stack – reduced vibration and audible hum.
Custom geometry – OD, slot count, skew angle and shaft length machined to drawing.
Ready for magnet over-moulding – sand-blasted surface for superior bonding strength.
ISO 9001 & IATF 16949 compliant – full PPAP documentation for automotive programs.
