Q:Please exchange the motor. Is it possible to adjust the speed with a governor?
Many domestic electric fans use bidirectional thyristor to do phase shift speed regulation. This kind of speed regulation is to reduce the input current so that the motor can not move fast and can only reduce the speed. Like the light desk lamp, it is forced to adjust.
Q:Can AC motors be controlled by frequency converter?
Only frequency conversion motor can use frequency converter to speed up, ordinary motor can not use frequency converter speed regulation.But it is possible to start the AC motor by using frequency converter.
Q:Can any 220V AC motors be reversible?
The motor can be reversed, just need to change the wiring, that is, to change the capacitance of the line can be adjusted
Q:How do AC motors keep in the same direction?
Because the working principle of AC motor stator is formed in a rotating magnetic field, then the rotor itself is a closed loop (induction motor) or a magnet (synchronous motor), the rotor rotation direction of magnetic field and steering only related to the rotation direction of magnetic field has not changed, turn to constant.
Q:Why are electric hair dryers divided into direct current motors and alternating current motors? What are their differences?
AC motor: wind, make the sound small, more durable, hot and cold big difference, large volume, stable current to prevent overvoltage protection AC fever dead machine, most hair dryer is now all communication, have built-in motor protection diode
Q:DC motor speed control performance is very good, why do we need AC motor?
AC motor: a machine used to convert mechanical energy and alternating current energy. AC motor has become the most common motor because of the great development of AC power system. Compared to the AC motor and DC motor, because there is no commutator (see DC motor commutation), therefore has the advantages of simple structure, convenient manufacture, relatively strong, easy to make high speed motor, high voltage, high current, large capacity. The coverage of AC motor power greatly, from a few watts to several 101000 watts, even millions of kilowatts.
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 speed the AC motor?
(1) rotor circuit series resistance: used in AC winding asynchronous motors. The range of speed regulation is small, the resistance consumes power, and the motor efficiency is low. Used of cranes.(2) change the speed of power supply voltage, the speed range is small, the torque decreases greatly with the voltage drop, and the three-phase motor is usually not used. Used for single-phase motor speed regulation, such as fan.(3) cascade speed regulation, in essence, is the introduction of additional rotor electromotive force, change its size to speed. It is also only used in wound motors, but the efficiency is improved.(4) electromagnetic speed regulation. Used only for slip motors. By changing the exciting coil current, stepless smooth speed regulation, the mechanism is simple, but the control power is smaller. Not suitable for long term low speed operation.
Q:The difference and advantage between DC motor and AC motor
DC motor:Advantages: 1., you can achieve a smooth and economical speed adjustment;2. does not require the coordination of other equipment, as long as the input or excitation voltage, current
Q:How many kW or more AC Motors should be started with the starter?
If only the General Motors (not including power plants, industrial production, motor) can refer to: civil, public and residential power grid direct power transformer power supply two, the former allows direct start for 11KW, which is 15KW
