Abstract It was proposed that sealing problems existed in the traditional canned pumps could be solved by using bearingless canned pumps.Introducing the principle of rotor suspension of a bearingless permanent magnet synchronous motor(BPMSM), the mathematical models of electromagnetic torque and radial suspension forces were given.According to the BPMSM control system function block diagram,the digital control system was described.In order to make software and hardware of the BPMSM control system work in coordination, the humancomputer interaction interface based on the BPMSM control system for realtime online debugging and control was designed and used.The experimental results showed that the humancomputer interaction interface for debugging and controlling the system can achieve the design goal quickly, at a rotation speed of 1 200 r/min, the central line of the rotorshaft oscillates near the equilibrium position(0, 0), the vibration amplitude of radial displacement is controlled in the range of 50 μm. Both have met the requirements for the realtime online debugging and control in the BPMSM control system. Such a humancomputer interface not only has important theoretical significance but practical value.
