Figure 5 is a perspective view of a prefabricated motor according to an embodiment of the present invention.

Referring to FIG. 5, the prefabricated motor 10 may include a rotor block 100, a connection block 200, a first connection auxiliary block 300, a commutator block 400, a brush block 500, and a second connection auxiliary. Block 600, rotary shaft block 700, stator blocks (800, 850), the front support block 900 and the rear end support block (950).

The prefabricated motor 10 may form a prefabricated motor 10 having a completed form as shown in FIG. 5 through the coupling of each block as described with reference to FIGS. 1 to 4.

The brush member 520 of the brush block 500 is electrically connected to an external power source to receive power to transfer power to the electrode unit 410 of the commutator block 400. The electrode unit 410 transfers the power supplied from the brush block 500 to the winding coil 110 surrounding the rotor block 100. The commutator block 400 may convert AC power into DC power.

When a current flows in the winding coil 110, a magnetic field is generated inside the winding coil 110, and both ends of the rotor block 100 are magnetically induced to the N pole and the S pole, respectively. If the outer end of the rotor block 100 is guided to the N pole, the magnet close to the rotor block 100 is the N pole, the rotor block 100 is rotated by the repulsive force with the magnet . In this case, the outer end of the other rotor block 100 is guided to the S pole, when the magnet close to the other rotor block 100 is the S pole, it is possible to obtain a larger rotational force.

When the rotor block 100 rotates half a turn and is disposed close to the magnet having the opposite polarity, each rotor block 100 is located close to the magnet having the other polarity and thus the attraction force is applied. This hinders the rotation of each rotor block 100, so it is necessary to change the polarity. Thus, the commutator block 400 and the brush block 500 change the direction of the current flowing in the winding coil 110. As a result, the rotor block 100 can obtain the rotational force by the repulsive force with each magnet again close. This process is repeated, the rotor block 100 may continue to rotate, the connection block 200, the first connection auxiliary block 300, the rotating shaft block 700, the commutator block coupled to the rotor block 100 The rotational force is transmitted to the 400 and the brush block 500. The prefabricated motor 10 can operate as a motor as mentioned above.

As a result, there is an advantage that the separation and coupling of each block is easy and simple.

Commercially available motors are compactly packaged and their internal configuration is unknown. As a result, it was difficult to intuitively understand and learn how the motor operates, that is, the aspect in which electrical energy is converted into mechanical energy. However, the prefabricated motor 10 according to the present invention can be suitably used as an educational tool because each sub-component is formed in the form of a block and the internal structure and the operation mechanism of the motor can be checked through the combination of the respective blocks.
