EV Motor Rotor

In-line automated inspection for EV motor rotors and spline shafts.

In-Line Spline Shaft Automatic Inspection Machine

An in-line gauging station for spline shafts on e-drive and transmission lines. The shaft is fed synchronously while the measuring head scans continuously along the full spline length, capturing over-pin dimension (M-value) and spline radial and axial runout in a single pass, with no offline sampling.

In-line spline shaft automatic inspection machine

Machine Layout

Compact in-line station with an integrated measuring head and operator interface, designed to drop into an existing production line.

Spline shaft measuring station

Measuring Station

A floating fixture holds the spline shaft during continuous axial scanning across the full tooth length.

In-line spline shaft inspection in production

In Production

Installed directly on the line, gauging each spline shaft as it is produced.

Features and Specifications

Continuous Axial Scanning

Continuous scanning across the full length of the spline in a single pass.

Synchronous Feeding

Synchronous feeding with multi-sensor dynamic sampling, measured at production rate.

Floating Fixture Architecture

Proprietary floating fixture design with quick changeover between part variants.

Over-Pin Dimension (M-Value)

Over-pin dimension measured directly on the line, without moving the part offline.

Spline Radial and Axial Runout

Radial and axial runout of the spline form captured in the same measuring cycle.

Measurement Repeatability within 1.0 um

Repeatability of 1.0 um or better supports tight tolerance control on splined shafts.

EV Motor Rotor In-Line Automated Inspection Machine

An in-line gauging station for permanent-magnet rotors. Magnetic field shielding protects the measurement system from the rotor's own magnetic field, so rotor cores and shafts can be gauged repeatably, directly on the e-motor production line.

Machine Layout

Enclosed in-line station with integrated gauging head, safety enclosure and operator interface.

EV motor rotor component drawing dimensions

Rotor Measuring Plan

Rotor bore, journal and overall length gauged to the tolerances called out on the component drawing.

EV motor rotor inspection in production

In Production

Installed on the line, gauging rotors as they are produced.

Features and Specifications

Magnetic Field Shielding

Shielding for permanent-magnet rotors keeps the rotor's magnetic field from disturbing the gauging system.

Measurement Repeatability within 1.0 um

Repeatability of 1.0 um or better for in-line rotor dimensional gauging.

Automated Part Handling

Automatic loading, gauging and unloading with no operator intervention in the measuring cycle.

Permanent-Magnet Rotor Ready

Configured for rotors with the magnets already installed.
