- 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: How to judge a three-phase ac motor
- How to measure the good and bad of the motor using the multimeter ohm. One, check to see if the road is open, U1 pairs U2 V1 to V2 W1 pair, check insulation U1 to V1, W1 U1, V1 W1 pair.
- 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: If the motor through reducer drive the load, the load moment of inertia is to convert to the motor shaft, namely, divided by the square of reduction ratio, and, after conversion of moment of inertia of the moment of inertia/motor = inertia ratio?
- In general use ordinary ac asynchronous motor, need not calculate inertia, the characteristics of ac motor is that he didn't have enough output moment of inertia, which is driven too heavy, though the steady-state torque is enough, but the transient inertia is too large, then the motor started to be rated speed, the motor will slow fast first, slowly speed, eventually reach the rated speed, so the driver is not shivering, the control effect is not big. But due to choosing a servo motor, servo motor is depend on the encoder feedback control, so its startup is very rigid, must achieve speed and position of the target, at this time if the amount of inertia to withstand more than motor, the motor will be shaking. So when calculate with servo motor as a power source must fully consider the inertial factor, need to compute movement eventually convert to the motor shaft of inertia, through the torque, moment of inertia calculation start time M = J x B, J is the moment of inertia, B for the angular acceleration, the calculation of the torque M less than the start torque of the motor to achieve smooth start.
- Q: What is the difference between ac motor and dc motor?
- The difference between ac motor and dc motor: According to the structure, the principle of dc motor is relatively simple, but the structure is complex and not easy to maintain. Ac motor is complex but relatively simple, and is easier to maintain than dc motor. The dc motor introduces the current to the rotor armature through the brush and the commutator, so that the rotor can force the force in the stator field. Ac motor (commonly used ac asynchronous motor, for example) is to put the ac electric flux into the stator winding, thus in the rotor creates a rotating magnetic field in air gap, rotating magnetic field in the rotor winding induced current, which make the rotor spinning force produced in the stator magnetic field.
- Q: Is the inductance of the stator winding of single phase ac motor constant? Does the inductance of the stator winding change when the motor turns?
- 100 millihenry's inductive coils are everywhere! The stator coil of an electric motor is an ac electromagnet with inherent inductance. Its relationship to the rotor is similar to that of transformer. The resistance of the stator coil, the strength of the magnetic induction, the rotation speed of alternating magnetic field and the voltage of alternating current. Current! Frequency! The inductance of oneself has relation! The rotor of the motor can change the electromagnetic strength of the stator. Just like the secondary coils of a transformer!
- Q: Which is good for dc motor and ac motor?
- The family seems to be alternating current, so it should be alternating current. Direct current also seldom listens
- Q: How does the three-phase ac motor identify the phase
- Three-phase ac motor do not need to determine the phase, as long as want to need to correct, the height error phase sequence is reversed, as to A, B, C, C, A, B or C, A, B are the same, belong to the correct phase sequence, three-phase ac motor direction according to regulations, if the inversion of the exchange of two wires casually put correct phase sequence.
- Q: About 100W ac motor is better than dc motor
- The answer is very specific. Ac motor and dc motor are used for different purposes, you can reconnect according to the theory, the industry experience of your relevant industry is applied. That would be better.
- Q: Does ac motor use the upper hall sensor
- There is little protection in domestic electric motors. Ordinary asynchronous induction ac motor does not require a general hall sensor. If you can monitor the speed of the motor, consider it.
