efficiency

Brushless motors typically have higher efficiency than brush motors. This is because brushless motors do not have the friction losses associated with brush and commutator, allowing for more efficient conversion of electrical energy into mechanical energy. In general, brushless motors are more efficient.

The efficiency of brushless motors can reach 85%-90%, while the efficiency of brush motors is about 70%-80%.

life span" 或 "life expectancy

Brush motors have brush and commutator that gradually wear over time, leading to a shorter motor life. The life of a typical brush motor can range from hundreds to thousands of hours. However, brushless motors do not have this issue, as they do not use brushes or commutators, which can significantly extend their lifespan.

The machine does not have these vulnerable parts, and its life can reach tens of thousands of hours, which greatly improves the service life of the equipment.

noise

Brushed motors generate significant noise when in operation due to the friction between the brush and the commutator. In contrast, brushless motors operate with very little noise, making them more suitable for environments with high noise requirements, such as

Household electronics, precision instruments, etc.

Control precision

Brushless motors, due to their electronic commutation and precise position sensors, offer higher control precision. They can achieve more precise speed and position control, making them suitable for applications with strict precision requirements.

Automation in the four fields of industry is widely applied.
