Disc Coreless Permanent Magnet Generator (PMG320-2KW)

Our disc coreless PMG has advantages such as low rated speed, low starting wind speed, compact size, lightweight design, and high efficiency. With coreless, anhysteresis, slotless construction and brushless operation, it delivers high performance for vertical axis wind turbines, gasoline generators, and hydroelectric generators.

2. Characteristics

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

3. Range of Application

• Vertical axis wind turbines
• Gasoline generators
• Hydroelectric generators
