- Functional add-ons (e.g., brakes, oil seals).
Hollow Cup Motor Principle; The difference between hollow cup motor and ordinary motorHollow CupMotoris a special type of motor, itsworking principleis different from ordinary motors. This article will introduce in detail the working principle of hollow cup motor and its difference from ordinary motors.Firstly, let”s understand the basic structure of a hollow cup motor. A hollow cup motor typically consists of an outer cup, stator winding, rotor magnet, bearings, etc. The outer cup plays a protective role in the motor, with the stator winding located inside the outer cup and wrapped in insulating material to generate a magnetic field. The rotor magnet is placed at the center of the stator and is usually made of permanent magnetic material. The bearings are used to support the rotating rotor.
