The Inner Workings of Plasma Cutting

Understanding how plasma cutting functions is crucial for appreciating its precision and versatility in metalwork.

  1. Rotor and Stator: Magnetic particle brakes consist of a rotor (the moving part) and a stator (the stationary part). The rotor is connected to the output shaft of the robot, while the stator is held in place.
  2. Magnetic Field: When an electrical current is applied to the stator, it generates a magnetic field.
  3. Hysteresis Effect: Ferrous particles within the rotor align with the magnetic field. This alignment creates resistance to the rotor’s movement, effectively slowing it down.
  4. Controlled Motion: By adjusting the current supplied to the stator, the magnetic field strength is modulated, allowing precise control over the rotor’s speed and movement.
