A Mechanical Freelancing Hub

We require an experienced Mechanical Design Engineer to design a high-efficiency Brushless DC (BLDC) motor specifically for a ceiling fan or blower application.

The objective is to develop a motor that delivers high airflow with minimal noise and low power consumption, without compromising performance.

Project Scope:

1. Electromagnetic Design: Develop the motor architecture, stator and rotor geometry, winding configuration, and magnetic circuit.
2. Mechanical Design: Develop the motor housing, shaft, bearings, mounting arrangement, and complete 3D CAD assembly.
3. Thermal Analysis: Evaluate heat generation, temperature distribution, and cooling requirements.
4. Simulation & Optimization: Perform electromagnetic FEA, thermal analysis, and CFD where applicable to evaluate motor efficiency, airflow, and operating performance.
5. Drive Electronics: Define the basic BLDC controller and electrical interface requirements.

Expected Deliverables:

• Complete parametric CAD model and STEP files.
• Winding specifications and motor design parameters.
• Electromagnetic, thermal, and airflow simulation files.
• BOM with readily available materials and components.
• Assembly drawings and manufacturing tolerances.
• Prototype testing plan covering airflow, acoustic noise (dBA), and power consumption at defined operating points.
