An Introduction To The Aluminium Wire Motor
Jan 14, 2017

Micro motor copper loss (including the main copper consumption + pay wire copper consumption + aluminum rotor loss) for the most part accounts for the loss, the temperature is sometimes a great influence on the performance, can actually temperature calculation, the method is: 1 of the stator winding copper resistivity 2.17 software defaults to 75 degrees, such as the stator winding of the actual test only about 20 degrees, is revised to 1.79. 2 aluminum rotor resistance rate is 4.34 software defaults to 75 degrees, such as when testing the rotor aluminum actually only about 20 degrees, is revised to 3.55. In fact, if no-load short-time test, aluminum rotor temperature will be lower than the stator winding temperature.
