5 Test method
5.1 Motor performance
5.1.1 DC permanent magnet, parallel excitation and series excitation tests
Use a DC stabilized power supply in series with a 10Ω/3A slide-wire varistor to test the starting voltage of the motor at no load and the working under different working voltages.
For current. Test with a class 1.0 DC voltmeter and a class 1.0 DC ammeter. Should comply with 4.6.1 and 4.6.2.
5.1.2 AC and Excited Magnetic and String Excited Magnetic Tests
Powered by an AC stabilized power supply, a 10Ω/3A sliding wire rheostat is connected in series to test the starting voltage and different operating voltages of the motor at no load, respectively.
Working current. Test with class 1.5 AC voltmeter and class 1.5 AC ammeter. Should comply with 4.6.1 and 4.6.2.
5.2 Coaxiality of commutator and rotor shaft
Test with V-shaped seat and dial indicator (with stand). Should comply with 4.3.4.
5.3 Contact position of brush and commutator
When the armature coil is in any position, the commutator will not short the two brushes. Test. Connect the motor experimenter to a DC power supply and connect the DC in series.
Ammeter and a sliding rheostat. First, short the two brushes and adjust the sliding rheostat to make the current value when the two brushes are short-circuited easily.
The current value during short circuit is different (for example, it is more than double). Then slowly turn the armature coil by hand.
Check the current indication value. If the current value suddenly increases to the current value when the armature coil turns to a certain position, it means at this point
The commutator shorts the two brushes.
5.4 Appearance, craftsmanship and structure
Sensory test. Should meet the relevant requirements of this standard.
5.5 Environmental test
Press JY 0009-1990 sections 4.6, 4.7 and 4.9. Should comply with 4.8.
