Q:The application of single phase ac asynchronous motor in washing machine
Washing machine motor should be called: capacitive single-phase asynchronous motor. The principle is on the startup winding in series a proper capacitor, due to the capacitor current lagging behind its voltage 90 degrees, so can produce a deflection on the stator magnetic field, the motor rotation. A washing machine is a clean appliance that USES electricity to produce mechanical functions to wash clothes. The washing capacity is divided into two categories: household and collective. China requires washing capacity in under 6 kg belong to household washing machine: household washing machine mainly by the body, wash to take off the bucket (some wash and take off the bucket separately), drive and control system, etc, some still is equipped with heating device. Washing machines generally refer to the use of water as the main cleaning fluid, which is different from the use of special cleaning solution and usually the dry cleaning which is responsible for the special person.
Q:Why does the motor need capacitance when the machine starts?
Only single phase ac motor USES capacitance, dc motor and three-phase ac motor do not need. The two single-phase motor coil does not produce a rotating magnetic field, must be in one of the series capacitance on the coil, make this branch of the current in another coil current in advance, the ability in a rotating magnetic field between the two coils, rotor rotation.
Q:Can two phase ac motor not be able to install governor?
Two phase ac motor can be equipped with governor; Ac motor speed regulation by changing the power supply frequency of ac motor, the extreme logarithm and the slip ratio, etc., to realize the speed adjustment technology.
Q:How do ac motor maintenance and maintenance?
electrical 1, the winding resistance equilibrium, 2, alternate insulation, 3, the winding is insulated from the earth, 4, is the terminal block loose or not, Whether the running current is normal, 5, what is the temperature rise at run time? Mechanical aspects 1, bearing noise, 2, the bearing temperature rise, The dust of the motor case should be cleaned regularly.
Q:Is it still a communication welder
Generally speaking, the ac welder appears on the market, the more common is the manual arc welding series, such as: BX1...
Q:Why does a single phase ac motor have to be a capacitor to start running?
A single phase ac motor is required to add capacitors for the official start of the operation: 1, the operation of the single-phase motor winding, can produce pulsating magnetic field, corresponding to the motor stator any electromagnetic fields, can only at this point including polarity changes direction and amplitude changes. That is, it cannot form a rotating magnetic field. In the stator, a starting winding is added, and the starting winding is 90 degrees in space with the main winding. Starting winding concatenated after a suitable capacitance, the equivalent circuit of the winding resistance becomes the inductance and capacitance in series circuit, as long as the capacitance value to meet current phase Angle leading voltage certain Angle, such as 30 degrees; At the same time, the current phase difference between the two windings is 90 degrees if the current of the perceptual running winding is 60 degrees, which is called the division principle. These two differ 90 degrees of electricity flow in time into the two differ 90 degrees of winding on the space, will be produced in the space (two-phase) rotating magnetic field, motor to spin the course
Q:How to control ac motor speed
The speed of the ac motor is dependent on the frequency of the power supply.This...... Nothing, change the current or the resistance.
Q:Is a single-phase carbon brush motor a dc motor or ac motor?
use Synchronous motors are used mostly in large generators, while asynchronous motors are used almost exclusively in motor situations. The synchronous motor can adjust the power factor by the excitation. The power factor of asynchronous motor is adjustable, so in some large factories, application of asynchronous motor is large, can be added a synchronous motor for condenser, used to adjust the plant and the power factor of power network interface. However, due to the synchronous motor of high cost, maintenance workload is big, now commonly used capacitance compensation power factor. Synchronous machine with exciting winding and the slip ring, need the operator had a higher level to control excitation, in addition, compared with those of asynchronous machine maintenance free maintenance workload is bigger; So, as an electric motor, most current asynchronous motors are chosen.
Q:What will be the result of the power supply to ac motor after the rectifier (not filtering)?
The ac motor will not be able to transfer the pulse direct current, the light is hot.
Q:What is the difference between dc motor and ac motor?
Series type of ac motor and dc motor structure, such as hair dryer, crusher, hand electric drill, etc. Used in the motor, just can't like dc motor with permanent magnets to generate the magnetic field. There is a commutator, carbon brush, there is electric spark in the work, the noise is bigger. General induction ac motor commutator and carbon brush, the input current of stator, rotor coil produces eddy current magnetic field, no spark, noise is small in work.
