- Q:Permanent magnet motor is dc motor and ac motor
- Because ac motor requires changing magnetic field, such ability and the frequency of the alternating current (ac) together to make the rotor rotation, so the ac motor may not use a permanent magnet. The magnetic field of dc motors can be constant, so you can use permanent magnets.
- Q:What is the effect of the ac motor on the connection of direct current
- If you want to run soybean milk machine with a 48V battery, you have to use the inverter to power the UPS power supply
- Q:The rated current of a single phase ac motor is several times that of an empty current.
- That's not how you understand it. 220V depends on whether you are a three-phase or single phase. For the three-phase P = 1.732 * U * power factor, for a single phase, P = UI. In other thermal relays we typically press 0.95-1.05 motor rated current. It doesn't seem to have been selected by 1.2 times.
- Q:What are the requirements for frequency conversion of ac asynchronous motors?
- Ordinary asynchronous motors can be used for short periods of time. In the long run, the frequency conversion motor is different from the ordinary motor. The reason is that the operating conditions have changed: 1, the frequency conversion asynchronous motor USES the frequency converter power, the waveform of the transducer output is PWM waveform, contains a large number of harmonics, the harmonics will add the added loss. The frequency of the base wave of the output waveform of the converter is varied, unlike the traditional fixed 50Hz. The operating conditions changed, and the corresponding design was different: The high peak of the output voltage of the transducer, the threat to the insulation of the motor and the need to strengthen insulation.
- Q:What is the ac motor made up of?
- The modern car is widely used in air-conditioning units, electric jet engines, electric control doors and Windows, electric adjustable seats, etc. The more advanced the car, the more power it USES. Today's mid-premium car generators are typically about 1 kilowatt. With the increase of automation and comfort, the use of electricity should be increased, but the installation space of cars is limited, and it is impossible to increase the power by increasing volume. As a result, engineers are working on cooling and installing positions. For example, install the generator on the top of the engine and try to stay away from the hot zone. The rear end of the generator is fitted with fan blades to enhance the cooling effect. BMW recently tried to improve the cooling effect of the generator by trying to cool it with water. The starter is made up of motors, actuators, and manipulators. Special start the engine, it needs strong torque, so want to through the flow of electricity is very big, hundreds of ampere, this feature determines it is different from the generator. For example, using dc series motor, the rotor and stator parts are made of coarsely rectangular copper wire. Driving mechanism adopt reduction gear structure; The operator USES electromagnetic magnetic absorption.
- 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:There is a difference between ac frequency conversion and dc frequency conversion
- Dc motor brush and the cause of the volume, restricting its scope of application of frequency control of motor speed can be developed by the fan and water pump, is due to the needs of the fan and water pump energy saving, frequency control of motor speed is the best choice, but I personally think that the price of electricity and the inverter's own, compared to the energy saving is pointless, because of the frequency converter investment back, at least need 5 to 6 years, in the five or six years, working condition of don't know what will happen. Therefore, inverter is best applied to speed regulation, and start on the performance and torque adjustment is not very demanding, and the occasion, this is the reason in general use frequency control of motor speed. So you can say that if you use dc speed control controllers to control ac motors that's the best, you can do that, and it's very difficult right now
- Q:Is the servo motor alternator? What's the difference?
- The servo motor has dc and communication. The typical difference is: The wiring of ac servo motor is a three-phase power line, and the encoder feedback line. Ac servo motor is no carbon brush, dc servo motor has carbon brush. To see whether it's communication or dc motors, it's simple: Look at the number, if it seems AC is communicating, DC is DC. Also, according to the power source, the communication is a three-compartment power line.
- Q:What are the advantages of the dc welder and ac welder? The better one?
- The biggest advantage of ac welder is that it is cheaper, and the advantage of dc welder is better than ac welder. Ac welder and dc welder are two types of welder's classification. Electric welding machine is the use of the positive and negative poles in instantaneous short circuit which is caused by high temperature arc to melt the solder on the welding electrode and welding material, cause the contact material combination of equipment. The welding machine can be divided into two types according to the type of output power Advantage of ac welder: cheap price; Disadvantages: high power consumption, low electric load (not easy arc), electric current instability, broken arc, sticky electrode, heavy, welding plain electrode. Dc welding machine advantages: low power consumption, high no-load voltage, current stability, easy arc starting), continuous arc, non-stick electrode, lightweight flexible, suitable for all brands of electrode; Disadvantages: the price is more expensive. Normally, dc motor is better than ac motor.
- Q:The voltage must be, what is the speed of the motor What is the rated voltage of the motor in alternating current? (with winding winding number)
- Frequency, the number of cycles per unit time is completed, how often is to describe the periodic motion of a quantity, commonly used symbols f or argument, said unit for seconds, symbols for s. To commemorate the contribution of German physicist herz, the unit of frequency was named Hertz, or Hz for short. Each object has a frequency that is independent of the amplitude that is determined by its nature, which is called the natural frequency. The concept of frequency is applied not only in mechanics and acoustics, but also in electromagnetism, optics and radio.
