The motor can be either a motor for an electric vehicle or a generator. This is the stator. What spins is the magnet. This generator is a low-voltage motor, and the generated voltage is estimated to be tens of volts, not more than 50 volts. 9 coils form a star, three-phase generator. This structure is generally used for small-power gasoline generators.
Below 50 volts, the hypothetical meaning is around 50 volts. It’s just experience, estimate it. Just by virtue of an impossible to say accuracy. When making a loop, you can add a load, such as a light bulb, between any two wires. Pay attention to the three-item balance issue: that is, connect three light bulbs between AB, BC, and CA respectively. Name the 3 heads A, B, and C.
Traditional motors refer to conventional permanent magnet motors. The tooth roots are easily saturated and the cogging torque is serious. The positioning torque of the motor is relatively large and it is difficult to start.
Disc motor: From its structure, we can know that the motor has good heat dissipation performance (the traditional motor stator wraps the rotor inside, and the heat dissipation is not very good.) And the disc motor is used in the wheel hub of the car and wind power should have unique advantages, but the power density is low.
Disc motor
Generally, the rotor and stator of a motor are installed inside and outside. In order to be thin, the disc motor has the stator on a flat base plate, and the rotor is covered on the stator. Generally, the stator is a coil, and the rotor is a permanent magnet or a disc with permanent magnets stuck on it. Also called disc motor.
