Responsible for the sustaining engineering of electric motor products, including design optimization, cost reduction, and production support.
1.
Motor Design & Development
Responsible for mechanical structure design and development of motors, ensuring compliance with PRD requirements and quality standard
Use CAD software for 3D modeling and 2D engineering drawing preparation
Conduct tolerance analysis to meet manufacturing and assembly requirement
Perform structural layout, critical dimension chain calculation, and tolerance analysis
Lead selection of key components (permanent magnets, silicon steel sheets, insulation materials, bearings, etc.), establish technical specifications, and conduct technical exchanges with suppliers
Output complete technical documentation including 2D/3D drawings, technical specifications (BOM, DFMEA), and test requisition forms
Optimize and improve existing product structures to enhance competitiveness
VAVE (Value Analysis & Value Engineering)
2.1 Cost analysis and optimization:
•
Disassemble motor BOM costs (stator, rotor, magnets, bearings, housing, etc.), identify high-cost components and cost reduction opportunities
•
Lead cross-functional (design, procurement, manufacturing, sales) cost optimization projects
2.2 Propose motor design improvement solutions:
•
Material substitution (e.g., copper wire winding optimization: enameled wire usage/insulation materials)
•
Structural lightweighting (cast iron to die-cast aluminum)
•
Promote component integration
•
Validate solution feasibility
2.3 Supply chain collaboration for cost reduction:
•
Work with procurement to develop new suppliers and promote localized material substitution
•
Evaluate technical capabilities of tier-2 suppliers
Mass Production Support & Maintenance
•
Provide technical support to manufacturing, quality control, and procurement departments to resolve design-related issues
•
Analyze motor failure issues from mass production or customer feedback, identify root causes, and propose improvement measures
•
Initiate, review, and track implementation of design changes (ECN/ECR)
•
Establish CBB (Common Building Blocks) for motor components to promote standardization and reduce customization
•
Participate in supplier technical reviews and capability assessments
