How to change ac motor to dc motor
You might as well turn the direct current into an alternating current to make it easier to use the inverter to convert the dc point to ac
The direct current motor is actually used by the brush and the commutator, and the actual winding flows through alternating current. The ac motor has no brush, dc motor requires a brush and no longer. Direct current motors use direct current, ac motors use alternating current. In general motors are communication, and the phase change of the high voltage dc is too abrupt to damage the motor. The battery (electric car) USES dc. Direct current electromotor refers to the motor of dc power supply (e.g. dry battery, battery, etc.). Ac motor refers to an electric motor that USES ac (e.g. home circuit, ac generator, etc.).
Application: dc motor and ac motor structure first, dc motor has a commutator (two half a copper ring), ac motor commutator. Dc motor is generally used in low voltage requirements of the circuit, dc power supply can be convenient to carry, such as electric bicycle is to use dc motor, and like a computer fan, radio cassette recorder motor etc. Difference method: the main thing is to see if there is a commutator, what power supply is used. The dc power supply for the commutator is the dc motor.
The motor is divided into the stator to stimulate the two kinds of rotors, and the ac motor is generally adopted by the stator, while the dc motor is generally used to stimulate the rotor. In other words, the electricity of the ac motor is usually added to the stator, and the electricity of the dc motor is generally added to the rotor. The reason for this is that the commutator's power is small, and the power motor cannot be powered by a commutator. But for small power motor, can adopt the method of replacement of commutator for dc transform, brush, commutator is copper ring any fitter will do, you can consult on the side of the road open locksmith shop teacher, generally charge in 50 yuan. However, although it is small power, you want to find a dc power source that can turn the electric motor to be not easy, estimate also want to buy the rectifier to convert alternating current to direct current electricity. Ha ha. Wish you success!
