ROTOR FOR BRUSHLESS DC MOTOR AND BRUSHLESS DC MOTOR

摘要

A rotor unit for a brushless direct current motor (BLDC motor) comprises a main body integrally formed with a rotor shaft and an annular ring magnet mounted on the main body. The annular magnet comprises an anisotropic hard ferrite and is laterally magnetized. The rotary shaft and the main body of the rotor unit may be formed from one plastic material. The rotor unit is supported within the BLDC motor via self-lubricating bearing seats.
