About This

• * This instrument verifies the relationship between the armature steering and the direction of current and the direction of magnetic lines of force. Grasp the principle of rotation of the motor.
• * This machine is mainly composed of base, rotating shaft, bracket, commutator, armature coil, pulley, pole shoe, permanent magnet, electric brush, terminal and other parts.
• * When doing a DC motor experiment, connect the 3V-6V DC voltage to the two terminals, that is, normal operation, the speed increases with the voltage, if it does not turn, it can be adjusted manually.
• * Pay special attention to the two brushes before turning on the power to avoid contacting the same commutator segment to avoid short circuit.
• * Permanent magnet N is extremely red, S is extremely white or blue, pay attention to the color code when installing.
