Sequence of a Brushed DC Motor

Sequence of a Brushed DC Motor

Here is the operation sequence of brushed DC motor.
・At the base point, coil 1 is situated at the S pole and coils 2 and 3 at the N poles, and they rotate clockwise by the attraction and the repulsion.
・At the position rotated 30 degrees to the right, coil 1 is situated at the S pole and coil 2 remains the N pole. The current stops flowing in coil 3, and then continues to rotate right by the attraction and the repulsion.
・At the position rotated 60 degrees to the right, coil 1 is situated at the S pole, coil 2 remains the N pole, and coil 3 is situated at the S pole, and then continues to rotate right by the attraction and the repulsion.
・At the position rotated 90 degrees to the right, no current will flow in coil 1. Coil 2 is situated at the N pole, and coil 3 remains the S pole, and then continues to rotate right by the attraction and the repulsion.

At the 120-degree position, coil 3 rotates to coil 1 position that is the base point, coil 1 to coil 2 position that is the base point, and coil 2 to coil 3 position that is the base point.
