Precision Thermal Management: Empowering Motor Reliability and Performance Enhancement
In the fast-paced electric motor industry, achieving efficiency, precision, and reliability is essential for producing high-performance motors that power everything from electric vehicles (EVs) to industrial machinery and renewable energy systems. The production of these motors requires advanced thermal processing technology to guarantee peak performance and long-term durability. As an industry leader in industrial ovens, we offer customized oven solutions specifically engineered to meet the demanding needs of the electric motor sector.
Insulation Coating Curing – Eliminating Breakdown Risks
Industry Challenge:
Uneven curing of stator/rotor insulation coatings can lead to partial discharge, accelerating wear and reducing motor lifespan.
Our Solution:
Multi-Stage Gradient Temperature Control: Stepwise temperature rise from 50–200°C (accuracy ±1.5°C) tailored to match the polymerization curve of epoxy resin and polyesterimide coatings. Laminar Airflow Speed Control: Adjustable vertical airflow (0.8–2m/s) ensures even coating, eliminating air bubbles and preventing excess coating fluid from dripping, ensuring film thickness uniformity (≥95%). H-Class Insulation Assurance: After curing, insulation withstands voltage >5kV (IEC 60034 standard), boosting motor MTBF by 30%.

Deep Component Drying – Eliminate Moisture-Related Failures
Industry Challenge:
Moisture trapped in windings can cause inter-turn short circuits. Corroded metal parts may result in rotor lock-up and costly downtime.
Our Solution: Vacuum Pulse Drying – Alternating negative pressure cycles at 80–130°C (-0.08 MPa) increase moisture removal efficiency by up to 50%. Dew Point Monitoring System – Real-time chamber humidity control (±3% RH), ensuring residual moisture ≤50 ppm (ISO 8573-1 Class 1). Anti-Oxidation Design – Nitrogen inlet port maintains oxygen levels below 1000 ppm to safeguard the active surfaces of copper windings and silicon steel cores.
Stress Relief for Metal Components – Prevent Warping Before It Starts
Industry Challenge:
Residual stress from stamping or winding can lead to excessive motor vibration and increased noise levels.
Our Solution:
Smart Annealing Profiles – Soak at 650°C followed by controlled cooling (≤3°C/min) to homogenize the microstructure
Over 90% Stress Relief – Verified via X-ray diffraction (per ASTM E915); rotor runout kept under 0.02mm
Custom Fixturing Available – Specialized hangers prevent high-temp distortion of shafts (load capacity: 1.5T/m²)
Core Component Heat Treatment – Reshaping Material Performance
Industry Challenge:
Insufficient magnetic permeability in silicon steel and low fatigue strength in shaft components can seriously compromise motor efficiency.
Our Solution:
Atmosphere-Controlled Heat Treatment – Uses a nitrogen-hydrogen blend (95% N₂ + 5% H₂) to prevent decarburization; surface hardness variation kept within ±2 HRC
Traceable Performance System – Automatically logs time-temperature profiles in compliance with AMS 2750E; supports exportable hardness and metallographic reports
Proven Efficiency Gains – Annealed silicon steel shows a 15% reduction in core loss, verified per GB/T 3655 testing standards
