Specifications: Double head generator Power: 2000W Model used: Single cylinder diesel farm tractor Length: 8" Width: 13.5cm Hole spacing 15.5 cm Thickness 13.5cm Wheel diameter 7.4 cm Hole diameter: 1.3cm Internal gear spacing: 7.4 cm Outer wingspan: 10.6 cm Weight: 2.89kg The wheels of the double head generator can be disassembled, and the four-hole fan can be installed without disassembly, and the single-hole fan can be installed after disassembly. Characteristics: 1. The permanent magnet silicon rectifier generator is a combination of an exciter silicon rectifier generator and a permanent magnet constant voltage generator. The adoptable magnetic stripe rotor, generator's own rectifier and full-wave voltage stabilization device not only reduce the cost but also increase the generator performance. It is a new generation product. 2. Usage: This product can be used for both AC and DC power. The wiring method is to connect the positive electrode of the battery to the generator ''and'' through the live wire controlled by the key, and the negative electrode can be grounded for charging and lighting. 1. The stator of the permanent magnet DC generator is pure copper wire winding and the rotor is a magnet 2. The diesel engine can be driven directly to generate electricity. The electricity generated can be charged or lit directly. 3. It is not necessary to install a regulator on the car with its own regulator 4. To measure the quality of the generator, you can directly use the diesel engine to drive the generator and use a multimeter to measure the plus and minus of the generator. Pole measuring voltage 14V charging generator voltage range of a battery (13V-18V) 28V charging voltage Generator voltage range of two batteries (23V-29V) 5. Can be used for single cylinder diesel engine, agricultural tractor 6. Rechargeable dual-use with light 7. It needs more than 1200 revolutions per minute, and the diesel engine can be charged while idling Wiring instructions 1. Connect a positive wire to iron the shell itself 2. The positive pole is connected to the second connection of the ignition switch (key switch). 3. The shell is the negative terminal and the negative terminal is connected to the negative terminal of the battery (battery), and the negative terminal can also be left unconnected Scope of delivery: 1 x Magnetic motor synchronous generator Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
