QM disc-coreless axial flux permanent magnet generators(QM generator hereafter) are three-phase AC generator with coreless structure of stator and multi-poles of rotor. Light weight, small size and high efficiency, starting torque could be

2.Basic Wiring Diagram

3.Working conditions

►Working altitude: Under 1000meters
►Working Temperature: Between +40°C and -20°C
►Relative air humidity (Average/month): ≤95% (Average temperature/month ≤25°C)
►Operation: Continuous service (S1)
►Over speed working
For PMG 1KW, maximum speed is 1.2 times of rated speed, run in no more than 2 minutes.

4.Installation caution

►Check data requirements of data sheet on surface of axial flux PM generator before installation
►Check insulation resistance between output wires and generator shell with 500megohms meter, testing value should not be less than 20megohms
►Without abnormal sound during rotating flexible confirmation of shaft or shell before installation
►Ensure installation steady and prevent the bolt becoming flexible and damaging
►It’s strictly prohibited to disassemble QM generator because of strong magnets inside
Pay attention to cleaning and inspection to prevent objects get inside QM generator during installation


►QM products do not require any particular maintenance
►Bearing checking every 5 or 10 years require maintenance to be carried out by the installer or user
►Operation of QM generator should under Generator Working Condition
►If the bearing is damaged; running noise or vibration increased significantly, bearing should be replaced immediately

►QM generator shall be subjected to rain/snow/dust/harmful gas and prevent collision during storage and transport. (Relative air humidity is less than or equal to 80%, temperature is between +40°C and -20°C
►Dumping and obverse are forbidden during storage and transportation
