Exchanges electric motors stator mould pressing magnetic trough wedge basic conditions Shafts wedge is the exchange of energy-efficient electric motors of a product, it allows the exchange of electric motors to increase efficiency, reduce Wensheng, a conservation; The advantage is low investment, simple measures, recovery period is short. 10 years, many plant based on the actual situation, the exchange of electric motors in the trial mould pressing magnetic trough wedge pilot study to won gratifying results. Using magnetic trough mud on asynchronous motor repair transformation is the key to the promotion of energy-saving items. But so far, mould pressing magnetic trough wedge absence of a unified standard. Magnetic trough mud is a major component of high-purity iron and high viscosity resins restored, it has a certain degree of Daoci performance. Will be magnetic trough in the mud floor pressure on electric motors Caokou solidification into the magnetic trough wedge electric motors, electric motors openings shafts become semi-openings or no beds to make space between the stator and rotor magnetic-distributed evenly between the effective length of time space, electric motors gas Cizu reduced. The magnetic flux increase, the electric motors operating at reduced # Additional surface caused by the effects of iron depletion and business leaders depletion would reduce 10%~15% empty currents, electric motors activated currents also declined, the operating noise and vibration improved tested in the same operation conditions, the general return, Wensheng to reduce 9~12 degrees. Electric motors operating as a body temperature heat market is becoming homogeneous, smaller temperature gradient changes to the delay aging electric motors insulation can play a certain role, thereby extending the operational life of the electric motors. At the same time it can increase the general efficiency of electric motors 1%~2%. Electric motors by the magnetic trough mud transformation, as a
