Altitude on the motor temperature rise, motor corona (high-voltage motor) and DC motor commutation have a negative impact.
The following three aspects should be noted.
(1) high altitude, the greater the temperature rise of the electric motor, the smaller the output power. But when the temperature rises with the altitude and decreases enough to compensate for the effect of altitude on temperature rise, the rated output power of the motor can be unchanged.
(2) high-voltage electric motor in the plateau use to take anti-corona measures.
(3) altitude is not good for DC electric motor commutation, pay attention to the choice of carbon brush material.
