- Q:The ac motor doesn't have a brush so how does the rotor rotate?
- The rotor generates a magnetic field based on the induction of the magnetic field. There are also some of the three-phase ac motor is a brush and winding, but the winding is on the rheostat, used to control the strength of the induced current, to control the speed of the rotor.
- Q:What is the classification of ac motor?
- According to the principle, the ac motor can be divided into two categories, synchronous motor and asynchronous motor, synchronous motor rotation speed and the frequency of the ac power source has a strict corresponding relation, in the running speed strictly keep constant; The speed of the asynchronous motor changes slightly as the load changes.
- Q:Control the power ac motor with thyristor or relay?
- I go to it more than one thousand watts of small motor with don't think so much speed is not necessary to use silicon controlled what contactor relays on the operation cost is too high it open just a matter of whomp up empty
- Q:Which is better for dc speed regulating motor and ac converter?
- See more power, to achieve what effect, low power, dc speed control usually are cheaper, high power estimation is ac motor, but not necessarily must use ac speed regulating motor. On the upfront costs, general inverter price range in 700-3000, probably look at your requirements and voluntary.
- Q:Is the servo motor a dc motor or ac motor?
- 4, a: what is the servo motor servo motor is also called force motor, in the automatic control system, is used as actuators, converts the received electrical signal into angular displacement or velocity of motor shaft output. Divided into two major categories of dc and ac servo motor, its main characteristic is, when the signal voltage is zero no rotation, speed decreases with the increase of torque and uniform,
- Q:The ac motor with more than one kilowatt will be activated by the launcher
- The start of the third motor Article 2.3.1 motor starting, the terminal voltage should be able to guarantee the mechanical requirements of starting torque, and caused by voltage fluctuations in the power distribution system should not interfere with other electric equipment work. Article 2.3.2 when ac motor starts, the voltage on the distribution bus shall meet the following rules: In general, when the motor is starting frequently, it should not be less than 90% of the rated voltage. When the motor does not start frequently, it should not be less than 85% of the rated voltage. 2, the load that is not connected to the light or other on the distribution bus line, and the motor does not start frequently, should not be less than 80% of the rated voltage.
- Q:Why should ac motors be used in parallel with capacitors
- It is. The motor will not work. In order to be able to in the case of single phase can also produce a rotating magnetic field, the designers in multiple access a coil at the same time, through a capacitor on the coil, leading to join this coil phase voltage phase shift. So it's going to be a single phase in the outside and it's already going to be a double phase. The two phases produce a rotating magnetic field. The principle of connection is illustrated
- Q:The type of speed adjustment of ac motor and the difference between them
- Variable frequency adjustable speed -- -- -- -- - this is by far the most common way of speed regulation, can achieve stepless speed regulation, after semiconductor converter circuit (or) change the frequency of the motor power supply, the mains frequency (= 50 hz) change as needed to achieve the purpose of speed regulation, frequency or the above formula: ac motor synchronous speed = 60 f/pole logarithm, th
- Q:The converter can control which motors
- The converter can be controlled General purpose motor This is used in situations where the accuracy of the torque speed is not high It has good energy saving and automatic control effect on the fan pump Vector control type inverter General motors can also be used to control frequency conversion motors Vector control characteristics have good control over torque load changes and speed above angular velocity A servo controlled converter And it's a lot more complicated to control the variable frequency special motor and to have better control and control over the vector
- Q:What is the connection of ac motor
- A single phase motor has three terminals, two terminals are connected to the fire line, and one is connected to zero.
