1. Brushless DC Motor (BLDC)

Advantages: The brushless design reduces energy loss and improves overall efficiency. Because there is no brush, the brushless motor has less wear and longer life. Smooth operation and low noise for applications requiring a quiet environment.

Disadvantage：High cost, the manufacturing process is complex, and the cost is higher than that of brushed motors.

Complex control circuits: Additional control circuits are required to manage motor operation.

2. Brush DC Motor (BDC)

Advantages: Simple manufacturing, relatively low cost. No need for complex control circuit, easy to drive directly.

Disadvantages: Brush and commutator wear faster, resulting in shorter life. Due to the contact between the brush and the commutator, the noise generated during operation is larger. High maintenance requirements: brushes need to be replaced regularly, increasing maintenance costs.
