Recently, a user of an electric tricycle asked me what is the difference between a brush motor and a brushless motor of an electric tricycle? Which is better? I will give you a detailed answer to this question today.
Let’s first look at the brush motor. Literally, we can know that the brush motor has carbon brushes. As a traditional electric vehicle motor, its main components include carbon brush, inverter, motor rotor, motor stator, motor shaft, motor end cover, bearing, etc. Its working principle is to connect the current of the rotor with the voltage regulating device by using the electric brush to play the role of voltage regulation.
The biggest advantage of the brush motor is its simple structure, lower cost, and better starting and braking effects. At low speed, the torque performance of the brush motor is excellent and the torque is greater. However, its disadvantages are also obvious. The carbon brush wears quickly and needs regular maintenance. In addition, compared with brushless motor, its noise is greater and its efficiency is lower. Finally, it is more affected by the environment, easy to demagnetize, and has a relatively short service life.
Let’s look at brushless motor again. Literally, we can know that brushless motor does not have carbon brushes. Its working principle is to use the exciter to connect with the voltage regulating device to regulate the voltage.
Brushless motor has many advantages, including strong anti-interference ability, low operating sound and high efficiency. In addition, the brushless motor has a longer service life, and basically requires no maintenance. However, brushless motor also has its own disadvantages, that is, higher cost and more power consumption in case of motor demagnetization.
In addition, from the application of view, brushless motors are more widely used than brush motors. From the current electric tricycle market, most electric tricycles use brushless motors. Even for electric four-wheel vehicles, brushless motors are more widely used than brush motors. So, does this mean that the brush motor is useless? The answer is no, because of the characteristics of the brush motor, many heavy-duty electric tricycles still use the brush motor.
Therefore, in general, the performance of brushless motor is better than that of brushless motor, but its price will also be higher. For users, if it is not a special heavy-duty electric tricycle, it is recommended to choose brushless motor. Of course, when selecting the motor, you should also polish your eyes to check whether the product certificate is consistent with the actual information, and be careful not to select the refurbished motor.
