[Abstract]:With the development of ocean and the requirement of military application, the working depth of submersible and underwater equipment is increasing, and the requirement of deep water motor, as an important driving component of underwater device, is also increasing. The active magnetic rotor and the driven magnetic rotor of the magnetic seal driver transmit motion, force and torque through the magnetic coupling. The active magnetic rotor is driven by the motor, and the magnetic force drives the driven magnetic rotor motion through the isolation sleeve to realize the non-contact transfer of the torque. The change seal is static seal, which can completely solve the leakage of shaft seal of mechanical transmission device, realize the motion transfer of zero leakage, and also protect the motor from overload. In this paper, according to the requirements of underwater motor seal, the overall structure of magnetic seal driving device is designed, and the magnetic circuit structure of magnetic seal driving device is determined. The magnet arrangement mode is studied and the magnet arrangement mode is determined. The reasonable selection of the ratio of length to diameter of magnetic circuit and the reasonable matching between the thickness of permanent magnet and the arc length of magnetic pole surface are analyzed, and the working point of permanent magnet material is determined. The torque calculation method of magnetic circuit and its power matching calculation and correction method are studied. The design calculation and analysis of torque of magnetic seal driver and the design of magnetic circuit and overall structure size are completed. The permanent magnetic material, soft magnetic material, yoke iron material and isolation sleeve material are analyzed and selected, the design of isolation sleeve is completed, and the eddy current loss and hydraulic friction loss of magnetic seal driver are analyzed and calculated. Based on the results of analytical analysis and calculation, the magnetic circuit of magnetic seal driver is simulated by ANSYS software, and the distribution of magnetic field in the model with different rotation angle difference, logarithm of magnetic pole and thickness of yoke iron is analyzed. The simulation results are consistent with the theoretical results. The information industry sensor product quality supervision and inspection center was commissioned to carry on the experiment and the test to the product prototype. The experimental results show that the performance of the magneto-force coupling seal driver prototype meets the design requirements.
