The difference between brushed and brushless motors for electric scooters

The difference between brushed and brushless electric scooter motors. Is it better to have brushes or brushless motors for electric scooters? This question has troubled everyone for a long time. Today, the two-wheeled electric scooter will give you a specific answer. An electric motor is a rotary electric machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or distributed stator winding to generate a magnetic field and a rotating armature or rotor. Under the action of the rotating magnetic field of the stator winding, a current flows through the squirrel-cage aluminum frame of the armature and is rotated by the action of the magnetic field. Some types of these machines can be used as motors or generators. The four major accessories of electric scooters are batteries, motors, chargers, and controllers. Among them, the three major components of battery, charger, and controller have been introduced in the previous article. The motor has never been explained to everyone, because consumers generally can’t see the motor, but when you buy an electric scooter, it is electric. The scooter manufacturer reminds you to ask the salesperson. The motor should be brushless as far as possible. As for motors, there are mainly two types: brush motors and brushless motors. In general, brushless motors replace mechanical commutation with electronic commutation, which is technically superior to brush motors. At the same time, the brushless motor has no gear or reduction gear, which reduces the unreliability of motor wear. Its efficiency is higher than that of brushed motors within a certain current range. The brushless motor runs almost without noise and has a life span 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 also higher. But at present, compared with brush motors, brushless motors will increasingly become the mainstream of the market. .
