Products Details
The explosion-proof performance of YBX5 series flameproof three-phase asynchronous motor complies with the provisions of GB/T 3836.1-2021 "Explosive atmospheres -Part 1:Equipment-General requirements". The the protection level and cooling method of the motors are also carefully designed to ensure their stable operation in various harsh environments.
Technical Advantages Of YBX5 Series Products
1. High efficiency, reaching the first-level energy efficiency of GB18613-2020, IE5 efficiency, which is about 1.5% higher than IE4 efficiency on average.
2. The product adopts a large three-circle structure, and the overall structural rigidity is high. The vibration performance of the motor is excellent, which can reach the B-level vibration level in GB10068.
3. High protection level, which can meet IP55, IP56, and IP66.
4. Optimized wind path structure, low motor noise, can meet the noise requirement of 80dB (A) sound pressure level.
5. The motor has a large temperature rise margin and high motor operation reliability.
6. Rich configuration, can be equipped with stator bearing temperature measurement, heating and vibration measurement devices according to user needs.
7. The junction box has a large space, which is convenient for users to install and maintain.
