- Q: Ac motor speed control method
- The most common method is to add a matching frequency converter You can also use a gearbox
- Q: How do I get 220v on the motor?
- If is to first of all should be low voltage motor step-down, dc motor need rectifier, filter, as needed if in ac motor is single-phase motor can be directly connected to the domestic load, is a set of three-phase motor single-phase electric into three-phase electric equipment. However, the typical three-phase motor is an industrial motor, directly connected to the industrial three phase electricity, while the civil motor is mostly dc motor or single phase motor.
- Q: Single phase synchronous alternator working principle
- The working principle of the dc generator is the armature coil alternating during induction electromotive force, the commutator with brush commutation function, make it from the brush end into the principle of dc electromotive force.
- Q: Which price is higher for ac motor and dc motor? Which service lasts longer?
- Accurately, if is the same specification, should be ac motor price is low, service life is longer, through electromagnetic induction ac motor rotors, relatively save electricity, and the internal heat production is less than a dc; Dc motor, the electric motor turns the electric motor, produces heat fast, but the effect is better. Therefore, you should choose according to the requirements when using.
- Q: Why does ac motor speed control system replace dc motor speed control system?
- The PWM control is the control core of the ac speed control system, and the final implementation of any control algorithm is almost done in various PWM controls. Has been put forward and the PWM control scheme of practical application to more than a dozen, articles about PWM control technology in many famous electric power international conference, such as PESC, IECON, EPE has formed at the annual meeting
- Q: How to eliminate the electromotive force of ac motor
- It is wrong to eliminate the anti-electromotive force of ac motor, which is the electromotive force that is opposite to the electromotive force of the power supply. There are multiple power sources in the circuit that can be turned against electromotive force. For example, two metal bars that cut the magnetic field in the same way back to the road may have an anti-electromotive force. There may be an anti-electromotive force in the presence of the electromotive electromotive force and induced electromotive force. In the case of a coil, the current of the electric current changes in the end of the coil. For example, the variation of voltage between the inductors in the LC oscillator circuit is strongly associated with the anti-electromotive force. The electromotive force is also produced when the motor coil is turning.
- Q: How do ac motors keep moving in the same direction?
- Most of the ac motor rotor is not current, power is in the little excitation current of synchronous motor synchronous runtime. Running in the rotor is current, this is in a rotating magnetic field induced current, the rotation of the rotor is also want to rely on the induced current, this is because the wire out of the current is induced in a rotating magnetic field, and wire in the magnetic field force, thus the rotor to turn up, until than the speed of the rotating magnetic field of the lower speed stability, this is the principle of asynchronous motor, so as long as the rotating magnetic field to the same, the motor to the same, how to obtain a rotating magnetic field, a direct current is not, the formation of the three-phase alternating current (ac) is itself a generator stator induced current in the rotor rotating magnetic field, so as long as he is input into the coil on the difference of 120 degrees, can be formed on the stator rotating magnetic field, single phase is somewhat hard to understand, but if you can put the sinusoidal magnetic field is decomposed into two same size changes, in the opposite direction of the synthesis of two rotating magnetic field results, as long as the rotor turns up later, and two the relative speed of the rotating magnetic field induced by the electric current cannot be integrated to zero, still can go up, just start up more troublesome.
- Q: What is the difference between dc brushless motor and dc brushmotor?
- The difference between a brushmotor and a brushless motor is whether it is configured with a commonly used brush - commutator. The commutation of the brush dc motor has been achieved through the contact of the graphite brush with the ring commutator mounted on the rotor. The dc brushless motor will give the rotor position feedback back to the control circuit through the hall sensor, allowing it to know the exact time of the phase change of the motor. Most manufacturers of brushless motor have three halls Effect location sensor. Because brushless motor does not have electric brush, reason also has no relevant interface, hence cleaner, the noise is smaller, actually need not maintain, life is longer.
- 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.
- Q: Do you start the coils when you are communicating?
- In addition, the resistance split-phase motor (such as thermal resistor start refrigerator motor), after the start, resistance value is very big, can think of the coil is power, does not work.
