Why choose plateau motor in high altitude environment

  Reminder, the plateau special motor refers to the series of motors used in high altitude areas, the applicable altitude can be from 1500 meters to 5600 meters, so do you know why high altitude environments must choose a plateau special motor?

  The high altitude, low air pressure, lack of oxygen, high cold, large temperature difference, and large wind and sand in the plateau environment are extremely severe tests for the ventilation and heat dissipation conditions, insulation and protection of the motor.If the ordinary motor is directly applied to the plateau environment, it may be burnt out due to the deterioration of operating conditions or cause frequent failures.

  First, the altitude will cause the insulation strength of the motor to decrease, and secondly, the breakdown voltage of the electrical gap of the motor will decrease.And in the operation of high-power and high-voltage motors, the corona initial voltage is reduced.

  In a high-altitude environment, the cooling effect of the air medium is reduced, and the heat dissipation capacity is reduced, which will cause serious heating of ordinary motors.In plateau areas, the air pressure is low and the lubricating oil (grease) is highly volatile, leading to increased mechanical wear.Therefore, ordinary three-phase asynchronous motors cannot be used for a long time in the plateau environment, because the normal use environment temperature of the general motors is -5°C to 40°C, and the location should be below 1000m above sea level.

  And with the increase in altitude, according to the different operating environment conditions of the plateau special motor, the focus and performance evaluation index of the plateau motor design will be optimized, so a new optimized design of the plateau special series motor is derived to meet the specified output power , The upper limit of the external dimensions is required, and the protective structure is adapted to the specific operating environment.

  Hubei Wanbang Motor Co., Ltd. is a motor manufacturer integrating R&D, design, production and sales of three-phase asynchronous motors. It has 19 years of experience in customization and production of plateau special motors, and has long-term cooperation with hundreds of mechanical equipment manufacturers.
