THE TECHNICAL WAY OF DECREASING THE TEMPERATURE RISE OF THE ELECTRICAL HOTOR OF SHEARER |
| |
| Abstract: | Pointing to the operating condition of the electrical motor of shearer, this article derives the relevant factors causing the losses in motor stator-and rotor when starting, frequently and the calculation of temperature rise, and analyses the relation between temperature rise and thermal load when running normally and the characteristiesof temperature distribution. According to the data from previous tests, it puts forward the technical way of decreasing the temperature rise of electrical motor in view of electro-magnetic calculation and structure design. |
