Specification
AgeRangeDescription : Adult
Brand : FYYKXWD
BulletPoint1 : 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.
BulletPoint2 : 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.
BulletPoint3 : 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.
BulletPoint4 : Requirements for power supply: When demonstrating the principle of DC motor, connect to DC power supply (dry battery or student power supply), and the voltage is 4V to 6V. The armature can rotate flexibly and speed up with the increase of voltage.
BulletPoint5 : Starting voltage 3.5V, running current 0.63A

Precautions
1. Pay special attention to when the armature passes a strong current for the motor experiment, such as the armature does not rotate after energization. The power should be cut off immediately and the cause should be checked. Do not energize the armature for a long time when the armature is not rotating to avoid burning the armature.
2. The brush and the copper ring of the collector ring should be kept clean and in good pressure of the brush and the copper ring should be tight enough to improve the sensitivity of armature rotation.
3. When doing motor experiments, do not connect the circuit board between the two terminals, so as not to burn the light-emitting diodes on the circuit board.
4. When doing DC motor experiments, if the energized voltage exceeds 6V, do not close the indicator light switch to avoid burning the indicator light. If the bulb is burnt out, remove the indicator light cover from the plastic frame to replace it.
5. When installing two permanent magnets, pay attention to the color of the magnet (namely the magnetic pole) and the color of the "U"-shaped bracket, and place the red and basket surfaces of the magnet against the red and basket surfaces respectively. Otherwise, the two magnetic poles are messed up, and the experiment will not be possible.
