Twin-Tubs Washing Machine 60W Spin Motor

Type test

If there are no special regulations, according to GB/T5171 regulations, it can be tested in normal temperature and

normal humidity( temperature 20±15℃、RH65±20％).

Test with DC500Vmagameter，insulation resistance should be over20MΩ；leakage current should be ≤0.5mA tested

with leakage current meter（test between terminal of leading-out wire from electric motor and non-charging metal）

It can stand AC1500V，50Hz insulation pressure-proof test for one minute. When testing online, then AC1800V

should be used，it would take 1 second instead.（between terminal of leading-out wire from electric motor and

non-charging metal rupturing current：10mA）

Range of fluctuation of supply voltage should be +10%,-15% when motor is running.

Temperature Rise

Motor installed in washing machine should operate according to the operating program of washing machine under

rated loading state, rated frequency, 1.06 or 0.94 times of rated voltage(or agreeable standards),temperature of winding

part can be tested with electric-resistance method，temperature of winding part can be tested with thermoelectric pair。

Limited value of temperature should be in accordance with regulations of preface2.

Wetfastness

There is no pocking or cracking on the appearance of motors if putting it in 40℃、90-95%RH，environment for

Cadmium Lead Mercury Hexavalent chrome PBB PBDE

≤100ppm ≤1000ppm ≤1000ppm ≤1000ppm ≤1000ppm ≤1000ppm

4

24h；after testing, test it with DC500Vmegameter,its insulation resistance should be over 1MΩ,and it can also stand

AC1250V，50Hz insulation pressure-proof test for one minute.

Salt Spray Test

According to GB/T 2423.17-93 Test Regulations in Basic Surroundings for Electrician and Electronic Products

Test Ka：Salt Spray Test Methods ,salting liquid is made up of sodium chloride and distilled water，mass percent of

salting liquid is 5%±1%，PH value should be 6.5～7.2 when the temperature is 35℃±2 ℃，if the motor is being atomized

in Salt Spray box for 24h continuously ,there should be no more than 1cm 2 lump pocking on the appearance of motor，

Shaft of the motor can not rust .

Abnormal Operation

In actual state of cooling, locked-rotor test was held on motor under rated voltage，electrifying time： motor with

S1 character of service can work for 15min, motor with S2 character of service can work for 5min. At the time electric

motor can stop within the prescribed testing time or the very moment overheat protector disconnects, winding

temperature of F grade insulation should not exceed 240℃，while B grade insulation shouldn’t exceed 225℃, branded or

molten metal shouldn’t appear during testing time. After the test, cool off to room temperature, it can stand 1min

dielectric strength test, tested voltage should be 1000V.
