Q:The electric fan is a dc motor, or the ac motor is good, why?
Dc motors are generally small power, and the general power is communication. First of all, I want to correct a concept, no good questions, dc motor and ac motor is each have their own characteristics and purposes, there is no best motor, only the best manufacturers. That means that there's no better problem with dc motors and ac motors. Dc speed regulation is very convenient, as long as the voltage is changed, and the torque is not affected. Ac speed is more complicated and is known as a frequency changer. It is suggested that ac motor should be used, which is mainly used for ac motor, and dc motor needs a rectifier to work.
Q:What is an ac driver? And the principle! Thank you very much!
Low frequency characteristics In low speed, the step motor is prone to low frequency vibration. The vibration frequency is related to the load condition and drive performance, and the frequency of vibration is generally considered to be half the frequency of the motor. The low-frequency vibrations, determined by the principle of stepping motor, are very bad for the normal operation of the machine. When the stepper motor work in low speed, general damping technology should be adopted to overcome the low frequency vibration phenomenon, such as add damper on motor, or drive the segmentation technology, etc. Ac servo motors are very stable, even at low speeds. Ac servo system has a resonance suppression function, can cover the mechanical rigidity, and internal system has the function of frequency resolution (FFT), can detect the mechanical resonance point, is advantageous for the system adjustment. Three, the moment frequency characteristic is different The output torque of the stepping motor decreases with the speed of the revolution, and falls sharply at high speed, so the maximum working speed is 300 ~ 600RPM. Ac servo motor for constant torque output, that is, at its rated speed (2000 RPM and 3000 RPM) of less than, can be rated output torque and constant power output above the rated speed for.
Q:Control the power ac motor with thyristor or relay?
Direct starting? Pay more attention on get a molded case circuit breaker with motor protection remote control words that do with contactor control circuit breaker short circuit protection Although a bit bad Make the correct choice is capacity
Q:According to the power of motor, how to select the contactor and switch?
Based on the capacity of the three-phase squirrel-cage asynchronous motor, the calculation method for selecting circuit breaker, contactor, heat component and conductor is as follows: 1, the capacity of the motor is set to X (kW), the rated current of the motor as: 2 * X (A), in general, with the motor nameplate rated current of the difference is very small, if not sure, can take the motor manual check. For example: motor power 7.5 (kW), rated at 15 (A); The motor power 55 (kW), the rated current is 110 (A).
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
Q:Is the mainstream subway car traction motor, ac or dc?
Dc, safety, economy, no harmonic damage, dc motor torque speed, high reliability, low volume,
Q:How to control ac motors with dc 24V voltage
The 24V contactor is also very expensive, with intermediate relays, and then use the intermediate relays to control the contactor
Q:The rated speed of ac motor
It is impossible to achieve 1500 RPM if there is no mechanical loss in itself, such as bearing friction, etc
Q:Why don't I have a dc 12V without a brush motor and I can connect to a third phase 12V?
It's just going to go from 120 degrees to 180 degrees, and it's wrong, it's going to go from 120 degrees to 90 degrees.
Q:What are the advantages of ac generators compared to dc motors?
Alternator's advantage is the advantage of developing energy, now is the main ac power on the consumption of energy, and this kind of generator maintenance convenient, and durable. And dc generator for dc energy consumption only, in addition to small household electrical appliances is large motor with this kind of dc power supply, small home appliance is not necessary to buy a dc generator for power supply? And large motor, need large generators to supply power, to know the large generator driven by either hydraulic or mechanical energy or wind need to consume large amounts of diesel oil, water or wind, and want to have big permanent magnet iron core or high power rectifier devices. Permanent magnetic iron core is one of the best in the dc generator, but also need high power permanent magnet generating large generator drive, and is very difficult to start, or excitation coil dc power supply, need to control dc again. A lot of trouble. Instead of using alternating current, the whole flow can also save energy. This is just my personal opinion, I don't know if it's right or wrong.
