Design And Simulation Of Jujube Pit Removing Machine By Rotating Principle

We know that the designer of the motor is always possible to reduce the leakage flux (including the slot leakage flux, the leakage magnetic flux and the end portion of the leakage flux harmonics) is generated, which is based on two factors to consider:1, in order to improve the stator and rotor windings while the flux linkage, the stator and rotor are in a higher permeability silicon steel sheet;2, in order to prevent a leakage magnetic field of the motor electrical interference external electronic device, a technique using a special electromagnetic shielding when necessary.In fact, the magnetic flux leakage outside the motor can react to a certain extent even the operating conditions of the motor the motor by analyzing the intensity of the leakage magnetic field can make the diagnosis of the motor efficiency. By analyzing the internal motor can produce leakage field electromagnetic mechanical mechanism (including rotor windings, stator windings and end winding) clarified the motor externally generated leakage magnetic field component composition, placing a simple magnetic induction coil pickup leakage through external motor different location flux. Found:magnetic induction coil and the motor shaft in the same plane (tangential direction detecting the motor flux) RMS voltage induced a positive correlation with the actual motor torque law changes.Based on the above analysis, we designed a Bluetooth-based non-intrusive leakage magnetic field of the motor external detection systems, and specially designed a set of leakage magnetic field detection, detection device measuring motor speed and motor efficiency measurement and PC analysis software.
