Magnetically suspended flywheel in gimbal mount - Test bench design and experimental validation

“…• Compare experimental and theoretical results in order to shed light on the validity of the model from [6] and discuss relevant improvements.…”

“…3. The rotor consists of an inner steel shaft 24 with the axial permanent magnet bearing (PMB) 28 bolted onto one end and a compressor wheel 19 bolted onto the 1 Tilting frame, 2 Gimbal, 3 Housing, 4 Accelerometer, 5 Power Supplies for AMBs, 6 Pneumatic Supplies, 7 Pneumatic Actuator Position Sensor, 8 Pneumatic Actuator for Pitching, 9 Pneumatic Actuator for Surging, 10 Rail, 11 Translating Frame, 12 Proximity Probe Conditioners, 13 Electronic Cabinet. other end.…”

“…Therefore, a mathematical model is needed. This motivates the work carried out in [6] where the derivation and application of a mathematical model governing the motions and forces of a rotor, housing, and gimbalmount on a moving foundation are carried out. The model uses a multi-physical approach in a Newton-Euler framework where motions of rotor, housing and gimbal can be directly extracted along with reaction forces in the system.…”

“…It is important to highlight that in all of 5 these cases, the authors decide to mount the FESS in a gimbal mount. The original contribution of each of these references consists of different experimental tests (a thorough account of the original contributions is found in [6]). They focus on experiments and do not address the mathematical modelling of the FESS.…”

“…The model is however based on numerous assumptions and simplifications which motivates the need for experimental validation. This work deals with an experimental set-up of the system modelled in [6].…”
