Torque characteristic analysis of slotted disk magnetic couplers
the slotted conductor disk complicates the magnetic circuit during operation
increasing the difficulty of calculating electromagnetic torque. A reliable electromagnetic torque prediction model was established
and its torque characteristics were studied.
Methods
2
A 18-pole 16-slot disk magnetic coupler was studied. Firstly
via the equivalent magnetic circuit method
induced eddy currents from adjacent and self-magnetic circuits were introduced as a branch into a new model. Considering 3D end effects and combining Ampere's and Kirchhoff's laws
air gap flux and output torque expressions were derived. Secondly
the coupler was simulated and analyzed by the finite element simulation software
obtaining distributions of air gap magnetic field and eddy currents
and torque variations with air gap thickness and speed difference under adjacent eddy current influence. Finally
a test platform was established to verify theoretical and simulation results.
Results
2
The results show that the results of theoretical calculation
finite element simulation and test are basically consistent. The proposed theoretical model has high accuracy
providing a reliable prediction model for studying the torque performance of such couplers.
