Unraveling the Secrets of Magnetic Brakes
At the heart of a magnetic brake lies an intricate interplay of electromagnetic forces. Let’s delve into the distinct principles and operations of various types of magnetic brakes:
-
Eddy Current Brakes: These brakes generate eddy currents when a conductive disc rotates within a stationary magnetic field. The induced currents oppose the disc’s motion, creating a drag effect that slows down the trailer.
-
Hysteresis Brakes: Utilizing magnetic materials with a hysteresis loop, these brakes rely on a cyclic magnetic field to align and re-align the material’s magnetic domains. This energy-dissipating process generates friction, contributing to the braking action.
-
Friction Brakes: In friction brakes, a magnetic force presses the brake pads against the brake disc or drum. The resulting friction brings the trailer to a halt.
-
Electromagnet Brakes: These brakes employ a magnetic coil that generates a magnetic field when energized. This field pulls an armature towards the coil, causing the brake pads to engage and slow down the trailer.
-
