Why Did General Motors Cannot Be Used In Plateau Area?

Altitude on motor temperature, motor Corona (high-voltage motor) and commutation of DC motors have a negative impact. Should pay attention to the following three areas:

(1) the high altitude, temperature rise greater output power more smaller. But when the temperature decreases with the increase in altitude compensates for altitude effect on temperature rise

The motor's rated output power can be the same;

(2) when used in high voltage motor in the Highlands to take Corona-resistant measures;

(3) elevation on the DC motor reversing negative, should pay attention to selection of carbon brush material.
