Eddy Current Brake Simulation with EMWorks
Design, size, and validate eddy current brakes before building hardware.
This application note examines a rotary eddy current brake consisting of a copper disk, permanent magnets and a back iron core. Using EMWorks electromagnetic simulation, the study computes magnetic flux density, eddy current distribution, braking torque, eddy losses and disk speed for constant-speed and transient operating conditions. Torque–speed behavior and braking time are extracted to assess suitability for high-speed applications such as rail, roller coasters and rotating machinery.
This note studies a radial-flux hybrid excitation eddy current brake using 2D transient magnetic simulation. It compares electrical, permanent magnet, and hybrid modes in terms of braking torque versus speed, eddy current losses, and air gap sensitivity.
This note uses EMWorks to simulate axial permanent magnet and double-sided ventilated eddy current brakes, computing braking torque, power loss and temperature rise versus speed and time.
