Anti-corrosion magnetic pump is a common centrifugal pump in industrial production. It is necessary for acid and alkali resistance and corrosion resistance. Customers generally choose corrosion-resistant pumps with good corrosion resistance. Anti-corrosion magnetic pumps generally use electric motors. The material is different, what should I do if the motor loss of the magnetic pump is too high? In addition to converting the electromagnetic energy into mechanical kinetic energy, the motor also loses a part of the kinetic energy. The motor loss can generally be divided into variable loss, fixed loss and stray loss. three parts.
1. The variable loss changes with the load, including stator resistance loss (copper loss), rotor resistance loss and carbon brush resistance loss.
2. The fixed loss is irrelevant to the load, including core loss and mechanical loss. Iron loss is composed of hysteresis loss and eddy current loss, which is positively related to the square meter of operating voltage, in which hysteresis loss is also inversely proportional to frequency.
3. Other stray losses are mechanical losses and other losses, including friction losses of bearings and wind resistance losses caused by rotation of fans and rotors.
