Q:Who knows the main difference between dc motor and ac motor
The two point poles 1 and 2 dc motors are forever 1 is positive and 2 is negative and the ac motor is a very shallow sign of positive and negative points
Q:Is the synchronous motor not communicating?
Brushless dc motor is not a smooth direct current, but pulse square wave. Like synchronous motors, speed is associated with frequency of square waves.
Q:What is the difference between ac servo motor and three-phase ac asynchronous motor?
Generally speaking: Servo motor is able to accurately realize position, speed, torque control Ac asynchronous motor is used for general power output.
Q:Who made the world's first ac motor?
Correct to say that they are both a master of power system, invented the dc transmission and alternating current (ac) transmission system, respectively, to promote the wide application of these two kinds of power system, due to the belong to different companies and the fierce competition. A competition eventually after a series of alternating current (ac) is found that the benefits of ac over dc, tesla also be regarded as the inventor of the alternating current (ac) in the history. Alternating current (ac) is not a tesla's invention is, actually, but tesla also have their own original invention, and many of them are super era, so this condition on tesla historical position as a great scientist.
Q:How does the three-phase ac motor achieve constant power or constant torque output
Is generally frequency converter to realize, in the power supply of power frequency 50 hz, motor with frequency converter to belt, the inverter output below 50 hz, the motor is constant torque output, but in the inverter output above 50 hz, the motor is constant power output
Q:Is it still a communication welder
Never put off till tomorrow what you can do now promotion of inverter dc welding machine and high recognition are very popular, and in recent years the development of the quality of welding inverter also promoted to a higher level, failure rate also fell dramatically; The welding performance of the inverter welder is much better than the ac welder, so its market share is higher (compared to the ac). And in other series of welders (e.g., argon welding, square wave alternating current, gas welder, plasma...) The reverse welder's share is higher
Q:What subjects should be included in the purchase of ac contacts and motors?
These two should belong to the fittings, not be used alone, should be repaired equipment to use, so direct in the period of cost - repair cost is ok. Hope to help you!
Q:Is the motor for general electric tools ac motor or dc motor?
The general electric motor is ac motor. Ac motor has become the most commonly used electric motor due to the huge development of ac power system. Compared to the ac motor and dc motor, with no commutator (see dc motor commutator), so the simple structure, easy fabrication, quite strong, easy to make a high speed, high voltage, high current, the large capacity motor. Ac motor power covers a wide range, ranging from a few watts to several hundred thousand kilowatts and even a million kilowatts.
Q:How does the brush motor control the positive and backward rotation?
Usually have a brush motor circuit with dc power supply, as long as change the brush across the electrodes at the ends of the power supply, change the direction of the input current, can change the motor and reversing.
Q:Why is the ac motor chain divided by time is voltage
Voltage, the electric potential is equivalent to the rate of change of magnetic chain, namely the change of the magnetic chain divided by the amount of time variation, flux variation with magnetic chain is the quantity of the same dimension, their values are the same. So the base value of the magnetic strand divided by the base of time is the base value of the voltage.
