Product Q&A
Q:How does your permanent magnet generator work?
A:
Our generator needs to be driven by other energy sources like wind power, water power, or belts to generate electric power.
Q:Can your magnetic generator produce electrical power by itself?
A:
No, it requires an external energy source to drive it.
Q:What is the power range of your generator?
A:
We can manufacture generators from 100W to 5000kW.
Q:What is the rotate speed of your generator?
A:
The speed ranges from 20rpm to 3000rpm.
Q:Can you manufacture customized products?
A:
Yes, we can. Please provide detailed requests for power, rpm, voltage, size, and color, and we will make the generator according to your request.
