Sažetak
In order to study the magnetic field model and transmission characteristics of radial solid permanent magnet coupler deeply, an 11 kW experimental prototype of solid permanent magnet coupler is taken as the object, its operation principle is analyzed in detail, and based on moving magnetic field theory and transient eddy current equation, a complete magnetic field model is established by finite element difference method, distribution of electromagnetic field is solved and the mechanical characteristics curve is drawn, the rated torque, starting torque and maximum torque of the experimental prototype are obtained, operating parameters of the experimental prototype meet the design objectives and have certain overload protection functions. Based on the theory analysis, the structural design and processing assembly of the experimental prototype are completed. An experimental platform was built, the correctness of electromagnetic torque calculation process was verified by dynamic loading experiments. Furthermore, the fluctuating load buffering experiment was performed, and the load fluctuation was reduced to 30%, which proved the flexible transmission characteristics and impact relieved function.
