350W motor has a maximum speed of 30KM per H. DC generator: The working principle of a DC generator is to convert the alternating electromotive force induced in the armature coil into a direct current electromotive force through the commutation action of the commutator and brushes. The direction of the induced electromotive force is determined by the right-hand rule. Methods for limiting generator speed: Generally, short-circuiting the drive wires directly (without connecting to a power source) can generate a certain force to keep the motor stationary. Applying voltage to any two drive wires (with a suitable resistor added after calculating the current) can also prevent the motor from rotating.
