The main characteristics of the plateau area are:
The altitude has an adverse effect on the temperature rise of the motor, the motor corona (high-voltage motor) and the commutation of the DC motor. The following three aspects should be noted:
Plateau motor refers to the motor whose altitude is higher than 1000 meters. According to the national industry standard: JB/T7573-94 General technical conditions for electrical products under plateau environmental conditions, plateau motors are divided into many levels: they are no more than 2000 meters, 3000 meters, 4000 meters, and 5000 meters.
Plateau motors operate at high altitudes, due to low air pressure, poor heat dissipation conditions, and losses will increase and operating efficiency will decrease. Therefore, the same, the rated electromagnetic load and heat dissipation design of motors running at different altitudes are different. For motors that are not high-altitude specifications, it is best to reduce the load appropriately. Otherwise, the life and performance of the motor will be affected, and even burn out in a short time.
Due to the characteristics of the plateau will bring the following adverse effects on the operation of the motor, corresponding measures should be taken in the design and manufacturing:
