Q:The difference between a variable frequency motor and an ordinary AC motor
Due to the variable frequency motor under high frequency magnetic field, so the insulation level than ordinary motor, the principle is not ordinary motor with inverter driven, but in practice, in order to save money on many occasions with the need to speed motor to replace the ordinary motor, but ordinary motor speed accuracy is not high, energy transformation in the wind the pump in the often do. When the frequency converter motor is replaced by a common motor, the carrier frequency of the converter is as low as possible, so as to reduce the insulation damage of the high-frequency motor.
Q:What are the advantages and disadvantages of AC and DC motors?
AC motor without carbon brush and commutator, maintenance free, strong and wide application, but the characteristics to achieve performance equivalent to DC motor to be used to achieve complex control technology. AC motor is divided into two categories: asynchronous motor and synchronous motor. Asynchronous motor is divided into single-phase asynchronous motor, two-phase asynchronous motor and three-phase asynchronous motor according to the number of stator phases. The three-phase asynchronous motor is simple in structure, reliable in operation and low in cost.
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:What is the reason that the single phase AC motor is turned on and off?
Check the switch first, is there any bad contact?. After the problem of the switch is removed, the power is turned on, and whether the cold state can run normally every time. If there is a phenomenon that the cold condition can not work properly, the internal circuit or winding is not working.A single-phase alternating current motor is a rotating electromagnetic machine used to realize the conversion of electrical energy and mechanical energy.
Q:AC motor control chip
Alternating current machine: a machine used to realize the mutual conversion of 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. In the early 1980s, the largest turbo generator reached 1 million 500 thousand kilowatts. The [1-2] AC motor was invented by Nicola Tesla, an American scientist from Serbia.
Q:The similarities and differences between DC brushless motor and AC motor
Brushless DC motor, the actual result is essentially different from AC motor, it is the direct current through the electronic oscillation circuit into alternating current, the frequency is generally adjustable, used to change the speed.
Q:Why is Tesla's Model s electric vehicle using AC motor instead of the more popular frequency conversion DC motor?
However, with the development of frequency conversion, the performance of vector frequency conversion + frequency conversion motor is close to that of DC 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:What is AC motor?
AC motors are divided into two major categories: synchronous motor and asynchronous motor. The rotor speed of synchronous motor ns is the same as that of rotating magnetic field. It is called synchronous speed. There is a strict relationship between ns and the frequency of the AC current (f) and the magnetic pole logarithm (P) of the motor. Ns = f/P in china,The power supply frequency is 50 Hz, so the synchronous speed of the dipole motor is 3000 revolutions per minute, and the synchronous speed of the quadrupole motor is 1500 revolutions per minute. The rotor speed of an induction motor is always lower than or higher than the speed of its rotating magnetic field, and the asynchronous name comes from it. The difference between the rotor speed of a induction motor and the rotating speed of a rotating magnetic field (referred to as slip) is usually less than 10%. It can be seen that the speed of AC motor (synchronous or asynchronous) is controlled by the frequency of power supply. Therefore, AC motor speed is difficult, the best way is to change the frequency of power supply, and in the past to change the frequency of power supply is more complex. Therefore, before 70s, in the speed control occasions, the use of DC motors. With the development of power electronic technology, AC motor frequency conversion speed regulation technology has begun to be practical.
Q:What's the difference between a three-phase AC motor and a DC motor?
Squirrel cage type AC motors are of small size, light weight, low price and long service life, which are opposite to the direct current motors;But the DC motor speed performance is good, AC motor is a little bit worse.
Q:Why don't AC motors use commutators?
The principle of reading a book, the commutator is used to make the motor current is DC, and if you say that the generator has a commutator, is not ac?
