Why General Motors can not be used in the plateau region?
PubTime:2008/8/28 14:07:04 Hits:6263
Altitude temperature rise of the motor, motor Corona (high-voltage motors) and the DC motor commutation are adversely affected. Should take the following three aspects:
(1) above sea level, the greater the electrical temperature rise, the smaller the power output. But when temperatures rise with the elevation above sea level of compensation sufficient to reduce the impact of temperature rise, motor rated output power can remain unchanged;
(2) high-voltage motors used in high altitude to take anti-Corona;
(3) altitude of DC motor for the disadvantaged, attention should be paid to the selection of materials carbon brush.
