Plateau brushless dc motor with average the distinction of brushless dc motor manufacturers | | plateau brushless dc motor brushless dc motor in the south of anhui

What is the plateau BLDC motor? Its are main the feature is what? Plateau brushless dc motor is used in the brushless dc motor of elevation above 1000 meters. Refers to: according to the national industry standard JB/T7573 -94 plateau environment under the condition of electric products general technical conditions required plateau divides a lot of brushless dc motor, they are no more than 2000 meters, 3000 meters, 4000 meters, 5000 meters. The main characteristics of the plateau region: 1, air pressure, or air density is small. 2, the air temperature is low, and the temperature change is bigger. 3, air absolute humidity is small. 3, high solar radiation intensity of illumination. 5, and less rainfall. 6, gale days a year. 7, soil temperature is low, and freeze. For these reasons, the following adverse influence on the brushless direct current guild chance, so in the design, manufacture to take corresponding measures: 1, causes the decrease of strength of insulation: every 1000 meters, dielectric strength to cut 8 & ndash; 15%. 2, the clearance of the breakdown voltage to drop, therefore increase by elevation size corresponding to the clearance. 3, corona inception voltage is reduced, must strengthen the anticorona measures. 4 medium, air cooling effect is reduced, heat dissipation ability, temperature increase, every 1000 m, rising temperature will increase by 3 -10%, therefore to revised temperature limit. In the 5000 m air oxygen only 53% of the sea level air oxygen. Why can't the plateau using ordinary BLDC motor? Due to the plateau environment pressure is low, poor heat dissipation condition, the wastage of the brushless dc motor will be increased, lower operation efficiency. Not ordinary brushless dc motor of high altitude specification, the best appropriate load operation. Otherwise, the life of the brushless dc motor and performance will be affected, even destroyed in a short time. So using in the highlands of brushless dc confidential according to the rated operating mode using the electromagnetic load and heat dissipation redesign. Brushless dc motor has a wealth of plateau in the south of anhui brushless dc motor manufacturing experience, according to the needs of users, for users to customize in accordance with user condition of brushless dc motor of the plateau.
