Which is better, brush motor or brushless motor

Jun 20,2023

Both brushed motors (brush motors) and brushless motors have their own advantages and disadvantages, and choosing which one is better depends on specific application needs and personal preference.

Brushed Motor:

     advantage:
         Relatively simple and low cost.
         Faster response when starting and stopping.
         Under lower speed and load conditions, there is usually a higher starting torque.
     shortcoming:
         Relatively short lifespan, easy to wear and tear.
         High energy loss, relatively low efficiency.
         Requires regular maintenance, such as replacing brushes and brushes.

Brushless Motor (Brushless Motor):

     advantage:
         Longer life because brushless motors have no wear from friction.
         High efficiency, low energy loss.
         Fewer maintenance requirements resulting in fewer brush and brush replacements.
         Lower electromagnetic interference.
     shortcoming:
         Costs are usually higher.
         The response speed of starting and stopping is relatively slow.
         Under lower speed and load conditions, starting torque may be lower.


So if you are more concerned about cost and simplicity, and you need higher starting torque at lower speeds and loads, a brushed motor might be a suitable choice. However, if you are more concerned about longevity, efficiency and less maintenance requirements, and are not very demanding of high starting torque, then a brushless motor may be more suitable for your needs. Zhejiang Yihe Microelectronics Co., Ltd. specializes in the production of brushless motor. The core team has been engaged in this industry for more than 10 years. The application fields cover high-end UAV, smart home, security equipment, health industry, leisure industry, medical industry, white goods, unmanned driving, and other fields related to transmission.
