Q:How to connect the AC motor?
There are two kinds of three-phase AC motorStar: the three connecting terminals are connected with three phase lines of the three-phase power supply, and the three terminals are shorted together with wires or metal pieces.
Q:Why AC motor speed control system will replace DC motor speed regulation system?
At present has been put forward and the practical application of the PWM control scheme is more than a dozen kinds, about PWM control technology in the power of many famous international conferences, such as PESC, IECON, EPE annual meeting has formed a special. Especially the microprocessor used in PWM technology and the digital pattern, is constantly changing, from the initial pursuit of sinusoidal voltage waveform, sine to current waveforms, then to sinusoidal flux; from the optimal efficiency, minimum torque ripple, to eliminate noise, PWM control technology development has experienced a continuous innovation and the continuous improvement process. So far, new proposals have been put forward, which further proves that the research of this technology is in the ascendant.
Q:Braking principle of 220V alternating current motor
1. the basic structure of three-phase asynchronous motorThe construction of three-phase induction motor is also divided into two parts: stator and rotor.(1) stator:The stator is the fixed part of the motor, which is used to produce rotating magnetic field. It is mainly composed of stator core, stator winding and frame.(2) rotor:The rotor is the main part of the rotor. There are two kinds of rotor, squirrel cage and wound rotor. Grasp their respective characteristics and differences. The squirrel cage type motor used for medium and small power (100k or less) is simple in structure, reliable in operation and convenient in operation and maintenance. Winding type can improve startup performance and speed regulation. The air gap between stator and rotor will affect the performance of the motor. The general air gap thickness is between 0.2-1.5mm.
Q:Causes of insulation breakdown in AC motor voltage withstand test
In the withstand test, the test voltage is too high and exceeds the specified value.
Q:In the main circuit of AC motor, fuse can be used as short circuit protection, can it play the role of overload protection at the same time, why?
If the current of the motor is working normally is 10A, if there is a fuse that can work stably in the case of 10A, the case of 11A will be blown. So because the motor load for a short period of time (a few seconds) suddenly become larger, up to 12A, and then returned to normal, it is not to endanger the safety of the motor (motor temperature rise, not what) without the need for protection, but the fuse has melted. That's what we don't want to see.
Q:Is servo motor AC motor? What's the difference? How can I tell whether it is AC or DC?
Want to see is AC or DC motor, is very simple:Look at numbers. If AC seems to be communicating, DC is dc.Also according to the power line view, AC is the three car power cord.
Q:What are the speed regulating methods of AC motors? Detailed point
1. use frequency changer to change power frequency speed regulation, speed range is wide, stability smoothness is better, mechanical characteristic is hard. That is, with the rated load, the speed drops much less. Stepless speed regulation. It is suitable for most three-phase squirrel cage asynchronous motors.2., change the magnetic pole logarithmic speed regulation, belong to level speed regulation, speed adjustment smoothness, generally used in metal cutting machine tools.3. change slip speed regulation.
Q:The similarities and differences between DC brushless motor and AC motor
Although the DC motor is supplied by direct current, the coil inside the rotor is still in the AC circuit. A live brush DC motor is commutated by an electric brush. And brushless motor is through the inverter circuit to DC into AC, and then to the coil. 12V cooling fans are common. It's commonly used in mainframe computers.AC motor does not need commutator (brush). Generally, permanent magnets are not needed. It would be nice to want to know more about buying a book on the principles of the motor
Q:Why is an AC motor more popular than a direct current motor? System description, thank you.
The reason of AC motor is common and convenient power supply: power generator and transformer, transmission and distribution in the form of communication, AC power supply, the utility grid can be directly used for AC motor is simple and convenient; DC motor to be alternating to direct before use, trouble.2, AC motor especially the induction motor, has the advantages of simple structure, easy manufacture, convenient installation, reliable use, low cost, high efficiency; and the DC motor is complicated in structure, manufacture and installation of trouble, use is not reliable, high cost, low efficiency.
Q:AC speed regulation motor + turbo reducer instead of cam cutter + AC motor?
The main error in cam dividers is that:1, because of the impact of inertia, resulting in errors caused by elastic deformation2., because of inertia lead to overshoot error3, cam gap caused by machining gap error
