8.Note:
DC electric motor experiment：input 3V - 6V DC through wires and terminals, the coil will rotating, and speed up when voltage step up.
To avoid short circuit, two electric brushes never touch the commutator segment.
Its working voltage is DC 3.0V-6.0V. And DC12V is not recommended.

9.Installation Steps:

• Step1: Install magnet bracket on the plastic seat and fixed by M3 screw and M3 nut.
• Step2: Install 1pc rotor bracket at first and fixed by M3 screw and M3 nut.
• Step3: Install another rotor bracket and rotor/commutator/armature coil and fixed by M3 screw and M3 nut.
• Step4: Install pulley on the rotor.
• Step5: Bend the angle of the electric brush
• Step6: Install electric brush and fixed by M3 screw and M3 nut.
• Step7: Install Red+Black Terminal and fixed by M4 screw and M4 nut.
• Step8: Install Permanent Magnet.
• Step9: When you finish the motor assembly, please turn the rotor bracket to let the gap middle between the 2 brushes.
• Step10: Connect to the cable on the terminal and then connect it to DC 3.0V-6.0V power to do a test. 

( Please NOTE:

1. To avoid the short circuit, two electric brushes never touch the commutator segment. 

2. Its working voltage is DC 3.0V-6.0V. And DC12V is not recommended. )
