Stator Core Fixture: Weight Capacity 50 kg, Min Stator OD 80 mm

Component Specifications

Definition

A specialized industrial fixture designed to securely clamp and position stator cores during the winding process in three-phase induction motor manufacturing. It ensures precise alignment and stability while allowing automated winding heads to apply copper coils with consistent tension and layering accuracy.

Working Principle

Utilizes hydraulic or pneumatic clamping mechanisms with adjustable jaws to accommodate various stator core diameters. The fixture rotates on a precision spindle synchronized with the winding machine's programming, maintaining exact angular positioning for each coil slot during the winding sequence.

Materials

High-strength aluminum alloy (e.g., 6061-T6) for the main body, hardened steel (AISI 4140) for clamping jaws, polyurethane wear pads, and corrosion-resistant fasteners (stainless steel 304).

Misalignment can cause uneven winding distribution
Wear on jaw surfaces over time affects grip

FMEA Triads

Trigger: Hydraulic/pneumatic pressure loss
Failure: Insufficient clamping force leading to stator slippage
Mitigation: Install pressure sensors with automatic shutdown if below threshold

Trigger: Bearing wear in rotation mechanism
Failure: Angular positioning errors during winding
Mitigation: Regular lubrication and replacement per maintenance schedule
