SDM Magnetic Rotor
As one of the most representative magnetic assemblies, rotor assemblies are consists of iron part and permanent magnet. Actually,
sintered Neodymium magnet, sintered Samarium Cobalt magnet, bonded magnet, and sintered ferrite magnet are all can be used for
rotor assemblies according to different application, motor type and assembly process. It should be noted that laminated magnets
made by magnet segmentation technology are also served to assemblies to decrease the eddy current loss.
1. **Stator:**
- The stator is the stationary part of the motor. It consists of a core made of laminated sheets of iron or steel, with slots to hold insulated copper windings. These windings are connected to an external power supply and carry alternating current (AC) or direct current (DC) to generate a rotating magnetic field.
- The main function of the stator is to produce a magnetic field that interacts with the rotor's magnetic field, causing the rotor to rotate.
2. **Rotor:**
- The rotor is the rotating part of the motor. It typically consists of a core with conductors (often copper bars or aluminum bars) arranged in slots, which are short-circuited at both ends by conducting rings or bars.
- When electric current flows through the rotor windings, it generates a magnetic field. This magnetic field interacts with the stator's magnetic field, resulting in torque and causing the rotor to rotate.
In summary, the stator creates a rotating magnetic field using the electrical power supplied to it, while the rotor reacts to this field, causing the motor shaft to rotate and thus converting electrical energy into mechanical energy. This process is fundamental to the operation of electric motors in various applications ranging from industrial machinery to household appliances.
