Disc Coreless Permanent Magnet Generator (PMG320-3KW)

Our disc coreless PMG has advantages such as low rated speed, low starting wind speed, small volume, lightweight design, compact structure, and high efficiency. With coreless, anhysteresis, slotless construction and brushless operation, it delivers reliable performance for wind, gasoline, and hydro generators.

2. Characteristics

• Coreless, anhysteresis, slotless — very low starting torque.
• No iron loss — ensures high efficiency.
• Unique coreless precision winding technology — precision coil design.
• Rare earth permanent magnets — multipole, mean gap, high power density and high output power.
• Low-speed direct drive — no torque fluctuations.
• Compact structure — high ratio of power to volume.
• No iron loss — low calorific value and small temperature rise.
• Simple structure — easy to install.
• Brushless structure — maintenance-free.
• —

3. Range of Application
