Simple Assemble Kit for School Labs Physics Science Educational Small Motor Model Motor Model Small Motor Experimenter Physical Model Teaching Aids

Name: Small Motor ModelSize: 140*90*100mm/5.51*3.54*3.93 inWeight: 200gRange of application: verify the relationship between the armature steering and the direction of the current and the direction of the magnetic lines of force. Grasp the principle of rotation of the motor.Main Specifications1. The size of the permanent magnet is 22*20*20mm, the magnetic induction intensity Br is not less than 72mT, the N pole is painted red, the S pole is painted blue or white, and the end should be ground flat.2. The radius of the arc part of the pole whip is 23mm, one piece is painted red and the other is painted blue or white.3. The rotor (armature) coil should be flat and symmetrical. The end of the core is a circular arc with a diameter of 42mm, and the core should be firmly combined with the rotor shaft.Precautions1. This instrument is a combined teaching aid. Please read the manual carefully before use, and be familiar with the performance, structure, principle and method of use of the instrument, so as to avoid improper use of the instrument.2. Please put it in the original position after use, so as not to lose the accessories and affect the next experiment.Prevent: high temperature, humidity, collision.

• * 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.
