- Q: Why should ac motors be used in parallel with capacitors
- A capacitor is usually a single phase, or 220V motor. The capacitors it takes are usually strung together in so-called starting coils, not in parallel. You know that in a three-phase machine, you have three phase electrical connections, so you have a rotating magnetic field. This magnetic field drives the rotor. There is only one phase of the single phase motor. If a single phase motor does not start the coils and start the capacitance, it will not be able to form a rotating field with a single phase connected motor.
- Q: What is the classification of ac motor?
- The three-phase asynchronous motor is the most widely used in the two kinds of rat cage and winding type according to the different rotor structure.
- Q: Does ac opportunity generate recoil voltage
- Yes, the magnetic field gives the coil a reverse electromotive force
- Q: Single phase single capacitance ac motor three wires wrong
- The single phase motor is divided by the main winding and the starting winding, and the wrong turn can also be turned, but the electric opportunity quickly overheat and damage, the proposal to seek a professional to show you.
- Q: Current ac motor has completely replaced dc motor
- Ac permanent magnet synchronous speed adjustment is achieved by changing the frequency, requiring the frequency converter. Dc motors do not need other equipment to help speed the adjustment, but their own structure is complex and manufacturing costs are high. Before large power controllable thyristor is used in large quantities, dc motor is used for most speed adjustment.
- Q: Multiple choice: the armature winding of large and medium ac motor is often used for the distribution winding of a double-spaced short distance. A reduces the current harmonics B, reduce the cost C reduces the air gap harmonic magnetic field
- A C D short distance can reduce the high frequency harmonic potential, which can also reduce the harmonic current and the magnetic field, because of the double layer, the cost increases
- Q: How does ac motor speed control
- There are three kinds of speed regulating methods One is to use a transducer to change the frequency of the power supply. The second is to change the extreme number of the motor (the requirement for the motor). Three is the slide differential governor. This doesn't actually change the motor speed. It is the variation of the differential clutch that is connected to the motor shaft, changing the speed of the clutch output shaft.
- Q: Three-phase ac motor star row and delta connection?
- Three-phase winding delta connection Three-phase asynchronous motor winding delta connection, when the power of a phase (L3) circuit, by the winding with cz series and winding ax again after parallel hybrid circuit of stator current whether meet the phase condition, the need to be calculated to determine. Because of the three-phase symmetric winding structure, the three-phase excitation impedance is equal, namely, Zma = Zmb = Zmc = Zm < Φ, the three phase stator current are: A = 0 12 / (Zm < Φ) = < - Φ, 0 = 0 c = 12 b/(2 Zm < Φ) = / 2 < - Φ. The current in the three-phase winding is visible, but the current phase is the same, and the current is not satisfied with the phase condition. Three-phase winding delta connection, three-phase asynchronous motor open phase, not only unable to start, lacks when starting the stator current is very big, if not in time to cut off the power supply, motor will be destroyed immediately. This is quite different from normal starting and must be taken seriously.
- Q: What is the power of ac motor
- Three-phase ac motor, three phase ac motor rated power = square root of 3 x x x rated current x rated voltage power factor efficiency.
- Q: What is the normal current of the three-phase motor of 3KW
- Normal ac motor, including FM motor, is not allowed to be plugged. By the external characteristic curve of ac motor, the ac motor will generate a "subversive current" burning machine when plugging. At this time the converter, if the vector is controlled, the motor is plugged and the torque current is not controllable. I've done this experiment. If the speed of more than 5 hz, can control the torque current (size can be smooth adjustment), and, using the encoder feedback is better than not using encoder feedback.
