Description

Specific specifications and requirementsPower requirements:When demonstrating the principle of a DC motor, connect a DC power supply (dry battery or student appliance) with a voltage of 4V to 6V. The armature can be flexibly held and speeds up as the voltage increases.DC generator demonstration: Move the two brushes to the middle of the collector ring, then connect the two terminals to the meter current of 5mA or 100mA respectively, and turn the indicator switch to "off".Alternator demo: Move the two brushes up and down respectively, so that the two brushes are respectively connected to the two copper rings of the collector ring, and the two wires are connected to the meter current of 5 mA, and the indicator switch Dial to "Off" and gently toggle the armature
