High-power coreless motors are a type of electric motors that can deliver high power output and high rotational speed. They are suitable for applications that require high-load and high-speed, such as electric bikes, electric scooters, and electric skateboards. To use high-power coreless motors effectively, you need to consider some factors, such as the voltage, the current, the torque, and the speed of the motor. You also need to choose the right size and type of the motor for your application. You also need to ensure the proper cooling and protection of the motor to prevent overheating and damage.
