tubular motor

Q:Soybean milk machine ac motor or dc motor: Soybean milk machine motor and other small appliances chooses to supply the power source is communication, but into the motor coil is used through commutator after dc, the dc motor also includes excitation coil. It is not economical and unrealistic to use dc motors directly under current power systems. "Ac motor" is a machine used to realize mechanical energy and exchange electrical energy. Ac motor has become the most commonly used electric motor due to the huge development of ac power system. Compared to the ac motor and dc motor, with no commutator (see dc motor commutator), so the simple structure, easy fabrication, quite strong, easy to make a high speed, high voltage, high current, the large capacity motor. Ac motor power covers a wide range, ranging from a few watts to several hundred thousand kilowatts and even a million kilowatts. In the early 1980s, the largest turbine generator was 1.5 million kilowatts. [1-2] ac motor was invented by the American Serbian scientist nikola tesla.

Q:Why does a single motor have a series of capacitors: In a three-phase current, the current in each phase of the phase is in itself a phase difference. The capacitor induction motor has two winding, namely the starting winding and the running winding. The two windings vary by 90 degrees in space. String on the startup winding capacity of a large capacitor, when running and start the windings by single alternating current (ac), because of capacitor in the startup winding current on time than the running winding current advance Angle of 90 degrees, to reach the maximum value. In time and space form two of the same pulse magnetic field, make the air gap between the stator and the rotor produces a rotating magnetic field, under the effect of rotating magnetic field, the induced current in the motor rotor, current and rotating magnetic field interact to produce electromagnetic torque, motor rotation. This is why uniphase motors are connected to capacitors.

Q:Dc brushless motor and ac motor: The dc motor is for direct current, but the coils inside the rotor are still alternating current circuit. A dc motor with a brush is replaced by a brush. Instead of a brush motor, the dc is converted into ac by a contravariant circuit and then coiled to the coil. The common one is the 12V cooling fan. It is commonly used in computer servers. Ac motor does not need a commutator (brush). Normally no permanent magnet is needed. ... To learn more about buying an electric machine, read it

Q:Does ac motor control circuit have to be communicated?: You need a commutator The commutator is a dc permanent-magnet series motor that allows the motor to continuously rotate to the original component. Structure, commutator is several contact piece into circular, connect every tap on the rotor respectively, connecting two electrodes called brush contact with the outside, only contact two of them at the same time.

Q:Which is better for dc speed regulating motor and ac converter?: 1 dc speed control system structure is complex, high cost of maintenance, complex structure of dc motor is an alternating current confidential (more than the armature, carbon brush), the price is high also 2 inverter easy to use, the price is not expensive, ac motor is cheaper (for dc motor). 3. The frequency converter and PLC is widely used in many fields.

Q:What is the difference between the excitation winding of ac motor and the armature winding?: Only the synchronous generator and the synchronous motor have excitation winding and armature winding. The general ac asynchronous motor is not excitation winding. Squirrel-cage asynchronous motor points and winding type two kinds big, the same stator winding structure, the squirrel-cage rotor cage bar, wound rotor rotor coil is an external device (can change the rotor impedance to realize variable speed). The "armature winding" is the "main power circuit" of the motor. Which power of the rotor and stator coil is "armature", needless to say, most stator coils are "armature winding".

Q:Ac motor speed control method: You can change the frequency, you can change the logarithm of the magnetic pole, and you can change the difference in three ways

Q:What are the advantages of the dc welder and ac welder? The better one?: compared with ac arc welding machine, dc welding arc stability, not easy broken arc and small six, splash. Dc arc welding machine can weld acid and alkaline welding rod, communication can only seven alkaline welding rod, welding machine prices, see you need to how much current welder, relatively speaking, dc welder expensive eight. Very save electricity, dc arc welding machine, is the development trend in the future. Personal recommendations dc welding machine. There is one of the biggest advantages is the dc welding machine is very light, 200 a to ten catties of convenient also move '

Q:There are several methods for alternating current motor: Other answer Ac asynchronous motor reverse connect braking has two forms: 1) the power brake, reverse connect braking - the electric motor of the three-phase power exchange of two lines, make access to the motor phase sequence, on the other hand, a rotating magnetic field inversion (in contrast to the rotor turning), the electromagnetic torque is a braking torque, motor soon stopped, must stop the motor when power off, otherwise will reverse starting; 2) pour la reverse connect braking - motor work normally when the load torque pulling reverse rotation, at this time of the electromagnetic torque is a braking torque, the braking torque motor reverse speed is not fast, but will not stop the motor;

Q:The motor in the hair dryer is ac motor, or dc motor: Is a dc permanent magnet motor, alternating current (ac) in the rectifier diode, part of the heating wire and the motor is connected in series, two head pressure drop of heat wire is very big, the motor voltage is low.
