The motor is a critical component of an electric scooter. Its power determines the top speed, climbing ability, load capacity and to some extent, the range of a scooter.There are two basic types of motors used in e-scooters today, including brushed DC (direct current) motors and brushless DC motors.
Brushed DC Motor
Brushed DC motors are based on an older form of motor technology that dates back to the 1800s. Brushed DC motors generate power using two sets of electromagnets.A large, cylindrical mechanical brush drags along a smaller magnet inside the motor, generating magnetic fields which power different coil phases.As a result, the inside of the motor turns continuously and generates power. Brushed DC motors have an efficiency of around 75-80%.
Brushless DC Motor
Also known as BLDC (brushless direct current) motors, brushless DC motors are a more modern technology that emerged in the 1970s. Brushless motors are almost like an inverted version of brushed motors.As such, the magnetic components that move in brushed motors are the parts that are stationary in brushless motors. These motors use digital switching circuitry to alternatively power different coils inside the motor.BDLC motors have an efficiency of about 85-90%. They’re also more durable and have higher power-to-weight ratios than their brushed equals.www.guoweimoto.com
