Yes, just rearrange the armature winding. Because the power remains unchanged and as the voltage increases, the current decreases. If it was originally a pile winding, it can be replaced with a wave winding;< /p>
Just ask the motor repairer: increase the voltage to 220V and let the power unchanged, and he will be able to find a solution.
Between hundreds of volts and thousands of volts. Hydrogenerator rotor DC voltage depends on the specific generator model and design parameters, and is typically between hundreds of volts and thousands of volts. In a hydrogenerator, the flow of water passes through the blades of the water wheel and causes the rotation of the rotor. Thanks to the electromagnetic induction between the rotor and the stator, the mechanical energy is converted into electrical energy. The voltage generated by the rotor is alternating current. After passing through a rectifier andother devices, it can be converted to DC for power supply or storage.
