Q:In the main circuit of AC motor, fuse can be used as short circuit protection, can it play the role of overload protection at the same time, why?
Therefore, the overload protection of the motor requires the use of a thermal relay that can accumulate heat effects. When the accumulated heat reaches a certain degree, the protection is started, and the motor is not allowed to continue heating up.
Q:Alternating current motor commutation
A sinusoidal voltage with a lead of 90 degrees or a phase of 90 degrees after a large capacitor is generatedAnd the original voltage can form a set of voltage difference of 90 degrees phase,.2 group voltage together can control its directionIf it's 90 degrees ahead, it's turning right. Then it will be reversed after 90 degrees
Q:Why is AC motor control more difficult than DC?
In addition, the DC variable voltage is easy to realize and the communication is troublesome. Therefore, the AC speed regulation uses frequency conversion speed regulation more frequently, but the frequency conversion speed regulation system is more complex than the DC voltage regulation speed regulation.
Q:How to distinguish AC and DC machines
The main difference between AC and DC motor is the power properties of different AC motors using AC generator, the AC and DC motor; using direct current, the generator is DC. Advantages of DC motor (AC motor and more): smooth speed control characteristics, can achieve economic. And AC motor need to use inverter, electromagnetic regulator and other components to achieve this function.
Q:What's the difference between a three-phase asynchronous motor and an ordinary one?
Ordinary motor motor and variable frequency motor of variable frequency motor, it is called the main appearance is different from the ordinary motor frequency conversion motor with forced cooling centrifugal fan, which ensures good motor cooling in low frequency and high frequency, frequency range also see nameplate motor internal structure can adapt to the specific operation of high frequency operation. Ordinary motors are generally allowed to operate under or less than 50hz.
Q:AC operation of AC motor control circuit must be used?
Yes, commutator is requiredThe commutator is a component of a DC permanent magnet series motor that allows the motor to continue to rotate.Structurally, the commutator is a plurality of contact pieces which are round in shape and are connected with each tap of the rotor respectively, and two electrodes are connected outside to be called an electric brush to contact with them, and only two of them are contacted at the same time.
Q:Why does high-speed rail use AC traction motors in China?
The design of asynchronous motor in AC motor is perfect, robust and easy to control. It is absolutely dominant in AC motor. The permanent magnet synchronous machine motor model is also very good, is the main application of high precision digital machine tools, hybrid electric vehicles, but also on some protection measures not in place, there is overheating phenomenon of demagnetization.
Q:For AC motors, when the voltage is constant, the frequency of the voltage becomes higher or lower, so what is the impact on the motor?.
The rise of the motor inductance frequency increases, suitable for high voltage, if the voltage at constant current is reduced; decrease of the power supply frequency of the motor inductance decreases for low voltage, current increases if the voltage is constant, and there may be magnetic saturation and heat and even burn.
Q:What is the principle of the single-phase AC motor in the washing machine?
Single-phase AC motor principle: with single-phase capacitor type motor: single-phase motor has two windings, namely starting winding and running winding. The two windings are 90 degrees apart in space. A capacitor with large capacity is connected in series on the starting windingWhen the running winding and the starting winding pass through the single-phase alternating current, the current in the starting winding is 90 times higher than the current of the running winding in time by the action of the capacitor, and the maximum value is reached first. Two of the same pulse magnetic field is formed in time and space, so that a rotating magnetic field produces the air gap between the stator and the rotor, the rotating magnetic field, the induced current in the rotor current, and rotating magnetic field interact to produce electromagnetic torque, the motor rotation.
