Generator & Motor Components Q&A:
* What type of generator is commonly used in VAWTs?
- **Permanent Magnet Synchronous Generator (PMSG)**: High efficiency, simple structure, most common choice.
- **Induction generator**: Lower cost, but requires grid excitation (suited for grid-tied systems).
- Small turbines may use modified DC motors.
* Do motors require waterproofing? What IP rating is recommended?
- Outdoor use: minimum **IP54** (dust and water splash resistant).
- Coastal or high-humidity areas: **IP65** or higher with anti-corrosion materials.
*8. How to match the generator with the blades?
- Match based on the blade’s **torque-speed curve** and generator ratings.
- Often used with a **charge controller** (e.g., MPPT) to optimize output.
