How much do you know about the principle of skateboard motors?
As a sports equipment, electric skateboard generally require the feeling of surfing. Therefore, its design requirements and performance are quite different from those of electric bicycles as a means of transportation.
Electric skateboard are required to have the characteristics of short starting time, fast speed, low noise, good climbing performance, and the system is often in critical locked-rotor operation due to climbing and various actions by the driver. These characteristics give the control system of the skateboard. The design has increased the difficulty.
Generally, driving electrolysis is divided into DC motors, AC asynchronous motors, switched reluctance motors and other types. In the current electric skateboard, DC motors are mainly used. Electric skateboard require low power, small size and high efficiency of the motor drive system. At present, most of the motors selected on the market are DC motors. In terms of structure, DC motors are divided into DC brush motors and DC brushless motors. The brush motor still occupies a dominant position in the market due to its easy control and low cost advantages, while the brushless motor has a relatively high cost due to the relatively complicated electrode structure and control circuit.
