Machine Details

The mechanical system consists of a nested Halbach magnet arrangement, driven by a servo motor. It generates a magnetic field with changing field strength. The flux density is up to 1.12T at a frequency ofup to 3 Hz. Furthermore, a piston pump, driven by another servo motor, generates an oscillating fluid flow to which a magnetocaloric heat generator can be connected. The electrical system is powered by a 624W power supply on 48V. The material insert consists of a housing with a sample of Gadolinium spheres and temperature sensors. The Microcontroller is responsible for controlling the overall system andprocessing the measurement results.
