53. tee of the safe using this machine And as a result we particularly stress the importance of grounding Sometimes there is an anesthesia in the working machine please check their grounding device firstly P 30 4 19 Motor l Summary of motor As the driving components motor drive the drum during washing and spin Currently the motor of drum washing machine usually have two speed motor and series motor 1 two speed motor is the running capacitance of single phase AC asynchronous motor 2 Nam Stator of the three phase AC motor embedded in the three phase windings 1209 If1t has symmetrical in the three phase windings it can produce rotating magnetic field Due to using single phase power the stator windings of washing machine in the single phase AC electromagnetic field generate field is a pulsating magnetic field And this pulsating magnetic field can be divided into two a rotating magnetic field and their speed equal to the opposite direction And therefore their synthetic torque is zero and motor can t be activated except issuing electromagnetic buzzing sound To start motor washing machine motor normally uses two measures First put embedded in the trough of stator two windings the main windings running winding and the vice winding start winding and two windings around axes in space in a 90 angle Secondly put a capacitor in series on the winding and therefore the same currents have different phase difference o

55. upply 4 18 Filter The power change of drum washing machine is in the scope and larger and in order to prevent its interference on the other household appliance and interfered by the other large appliance the filter 1s installed in the washing machine by CCC certification requirements Filter 1s made up of a group of capacitance usually three a group of inductance and a resistor In the power supply circuit 1t can inhale the high order harmonic from washing machine and earth The interference 1s from the high order harmonic from the power changes of washing machine as well as the disorders and alternating magnetic field according to the continuous changes of the current in the power cord The frequency and magnitude of change of its power 1s in the scope and larger that 1s from zero watts at soak to hundreds of watts at wash rinse and spin to nearly 2000 watts at wash with heating This change more easily aroused the obvious voltage fluctuations in the domestic circuit which effects the normal use of other electrical appliance These filters can filter out high order harmonic and earth EMC stressed interference and anti interference and as for washing machine 1t 1s important to reduce interference to others due to it has good anti interference The washing machine use alternating current that can pass capacitor and in practically filter will have a very small leakage current generally less than 2mA Good grounding is the guaran
