Do you prefer the high speeds of internal rotors or the efficiency of external rotor motors?

An electric motor consists of two components: the stator and the rotor. The stator is a stationary component that generates a magnetic field through the current in its windings, which affects the movement of the rotor.

An internal rotor motor means that the rotor rotates inside the stator. It features a small diameter, high power density, low moment of inertia, and can change speed and direction within milliseconds. Most of the DC and AC machines on the market today use this type of motor. Inner rotor motors can be connected to multiple accessory units, while external rotor motors are more suitable for a wider controllable speed range.

An external rotor motor means that the rotor rotates outside the stator. It has the characteristics of high efficiency, high power and low energy consumption, and is often used in axial flow and centrifugal fans. We will add this technology to tools in the future. Those interested can contact us.
