- Q:What is the normal current of the three-phase motor of 3KW
- So, for common communicators, the open loop control and the motor plug are not able to control the torque. If the servo ac motor is adopted, the closed-loop speed control, Angle control and position control can be blocked. For ordinary motor, you can consider, mechanical lock or jammed, mandatory locked-rotor, has completed the user's technical requirements, and then let go of mechanical plugging turn institutions, for the next process control. Ac motors are easily burned if plugged or missing. Must first understand the motor winding dc resistance of the dc resistance is under 15 Ω (motor dc resistance is smaller, the greater the power from less than 1 Ω), if the blocked or lacks when the motor has lost its ac impedance, so only under 15 Ω loop resistance of the motor, then the current can want to how much (380 v, 0.35 KW, for example: 380 present 15 = 25, 25 A was greater than the motor coil current over-current value). Often lack of phase, so the motor over-current protection (by the hand of my circuits are lack of phase, over-current protection), the first one but problems is that the current changes, this will protect the motor.
- Q:Which is better for dc speed regulating motor and ac converter?
- The more power of the frequency conversion, the drive effect is better, because the dc speed adjustment is to lower the voltage to the lower voltage, and the resulting loss. The voltage is constant in frequency conversion, and of course there is no loss of pressure. It's cheaper to invest in dc in the first place.
- Q:380v's ac motor operates under 330v voltage
- It should be because your motor is not heavy, but it should not be used. It is harmful to the motor.
- Q:Does ac opportunity generate recoil voltage
- The coil of a relay generates a magnetic field when plugged in, When the power is disconnected, the magnetic field gives the coil a reverse electromotive force.
- Q:Which is better for a dc treadmill or an ac treadmill?
- On electricity to run the market at present is dc motor, but the dc motor is ac motor, durable, safe, that is to say, market exchange treadmill will be dominant in the future. Running on electricity, suggest buying a running machine. If commercial electricity runs in clubs for a long time, then you have to buy an ac treadmill.
- Q:What are the similarities and differences between the dc brushless and the ac brushless motor?
- The brushless DC (BLDC) and the brushless AC (the name for which the name doesn't seem to be used in Chinese) belong to the permanent magnet synchronous motor. The two types of motors do not depend on the armature current and the waveform of the anti-electric potential. If the inverse voltage and the armature current are the rectangular wave, that's the BLDC, if it's a sine wave, that's the BLAC. Of course the inverse electric potential is a rectangle and the current of the sine wave, becomes the BLAC operating mode, so the waveform of the current is seen in the end.
- Q:What is the difference between the three-phase ac motor and the second phase
- Single-phase motor inside there are actually two sets of windings, a set of winding is work, also is the main winding, a set of start winding, namely vice winding, single-phase motor due to the single-phase power supply, so won't produce a rotating magnetic field in the winding, but the pulse magnetic field, pulse magnetic field does not produce torque, so the motor won't turn, so let's give him a start winding, the power of the startup winding is from the power supply of the main winding, but with the phase shifting device such as the capacitance that current phase by phase shifting device after the current is different, also became a so-called two-phase, so inside the windings creates a rotating magnetic field, motor will turn up, I would say the rotation of the three-phase motor principle, are all the same!
- 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:What are the advantages of ac generators compared to dc motors? Why is it that today's big generators are talking about generating electricity and getting rid of dc power?
- The disadvantages of the single most important one: dc generator, commutator, commutator, to direct current (dc), however, general from the collector ring commutator and carbon brush, mechanical wear, coil and carbon brush to produce graphite powder is easy to pollution, malfunction. Second: industrial dominant, industry important mechanical - three-phase asynchronous motor, the power supply must be alternating current (ac), because an alternating current to produce a rotating magnetic field, the drive motor. Third: alternating current to direct current only needs rectifier bridge, economy, simple. But direct current turns into alternating current costs, and it's complicated
- Q:Three-phase ac motor star row and delta connection?
- Three-phase squirrel-cage asynchronous motor adopts - delta Y step-down starting advantage: Y connection of the stator winding, the starting voltage for direct using delta connection, a third of the 1/3 of the starting current to delta connection, thus features good starting current, the circuit is simple, less investment. The drawback is that the torque is reduced to a third of the triangular method, and the torque characteristics are poor. So the line is suitable for light or no-load start. In addition, note that the consistency of the rotation direction should be noted when the y-delta joins
