SP-30 STATOR (FS3208) B-11

1. Stator Functionality:

   • The stator is a crucial component of the sander's motor. It receives electrical energy from the power source, typically through brushes or windings.
   • This electrical energy generates a magnetic field within the stator's core.

2. Magnetic Interaction:

   • The magnetic field produced by the stator interacts with the rotor, which contains permanent magnets or additional windings.
   • This interaction creates torque, a twisting force that causes the rotor to spin.

3. Rotor Movement:

   • As the rotor spins, it drives the sanding pad attached to it, enabling the sander to perform its function of smoothing surfaces.

Influence on Speed

1. Indirect Speed Control:

   • While the stator does not directly control the speed of the sanding pad, it plays a significant role in determining it.
   • The design of the stator, including the number of poles (electromagnetic protrusions), affects how the magnetic field interacts with the rotor.

2. Speed Determinants:

   • The number of poles and the configuration of the stator influence the frequency of the magnetic field, which in turn affects the rotor's rotation speed.
   • A higher number of poles can lead to smoother operation and potentially higher torque at lower speeds, while fewer poles may allow for higher speeds.
