TIANQIHAO Ac/Dc Motor Generator Model Diy Physics Teaching Instrument, Dual Use Science Experiment Kit For Principle Explanation
TIANQIHAO
This instrument is used in junior high school physics teaching to demonstrate the structure and working principle of DC motors and AC and DC generators. It is a multifunctional combined demonstration motor. This instrument is designed based on the principle that the energized coil rotates in the magnetic field and the closed coil rotates in the magnetic field to generate current. This instrument is composed of "u"-shaped bracket, armature, magnet, collector ring, electric brush, base, rocker and upper cover. The upper cover plate has a pair of terminal posts and is connected with the corresponding brush holder, which can be used for installing circuit boards and external power supplies. One end of the brush is installed on the brush holder, and the other end is in with the copper of the collector ring, and can move up and down along the brush holder to adjust the position. Requirements for power supply: When demonstrating the principle of DC motor, connect to DC power supply (dry battery or student power supply) Displays the key components and operation of an electric motor with a durable frame designed for repeated classroom demonstrations.
