We all know the four major accessories of electric vehicles, batteries, motors, chargers, controllers. Among them, the three major components of the battery, the charger, and the controller have been introduced in the previous article. The motor has not been told to everyone, because motor consumers generally do not see it, but when you buy an electric car The manufacturer reminds you to still ask the salesperson.
Try to choose brushless motor. As for the motor, there are mainly two types of brush motors and brushless motors. In general, brushless motors replace mechanical commutation with electronic commutation, which is technically superior to brushed motors. At the same time, the brushless motor has no gears or reduction gears, reducing the unreliability of the motor wear. Its efficiency is higher than that of a brush motor in a certain current range. The brushless motor has almost no noise during driving and has a service life of more than 10 years. Of course, the price of the brushless motor itself is relatively high, and the controller is more complicated, and the cost is higher. But at present, compared with brushed motors, brushless motors will become more and more mainstream in the market.
Through the above introduction of motors by our electric vehicle manufacturers, everyone must have understood that general merchants will have certificates such as product manuals or warranty cards. How many of them will mention the content of the motor? Well, do n’t feel bad because the electric car you buy has a brush motor. In fact, the quality of the electric car should be considered comprehensively. The content of this article is for reference only.
