The utility model relates to a maglev wind-magnetism heat generating device. The maglev wind-magnetism heat generating device comprises a wind turbine, a first rotary shaft, a gear speedup mechanism, a second rotary shaft, a rotor plate and a water tank, wherein the wind turbine is connected at one end of the first rotary shaft, the other end of the first rotary shaft is connected with the gear speedup mechanism, the gear speedup mechanism is connected with the second rotary shaft, the rotor plate comprises an upper rotor plate and a lower rotor plate which are fastened on the second rotary shaft, permanent magnets are arranged on the lower surface of the upper rotor plate and the upper surface of the lower rotor plate, the water tank is arranged between the upper rotor plate and the lower rotor plate, and the upper end face and the lower end face of the water tank are heating plates. The maglev wind-magnetism heat generating device is capable of converting wind energy into heat energy, and mechanical friction is effectively reduced by combining an axial permanent-magnet bearing and a radial mechanical bearing; meanwhile, start-up wind speed of the wind turbine is decreased, and application range of the heat generating device is enlarged; compared with the conventional heating manner, the maglev wind-magnetism heat generating device free of smoke, flame and pollution has better application prospect, is complementary with a solar water heater, and is of great significance to alleviating shortage pressure of energy resources and protecting the environment.
