- Insulation Class: Class F Insulation
- Temperature Rise: Class B stator winding temperature rise (measured by resistance method, not exceeding 80K when S.F: 1.0)
Applicable Conditions：
- Power Supply Conditions: Voltage fluctuation within ±10%, frequency fluctuation within ±5%, maximum comprehensive fluctuation of voltage and frequency within 5% (with frequency fluctuation not exceeding ±5%).
- Application Site: Locations in Zone 1 and Zone 2 of explosive gas environments.
- Ambient Temperature: -20～50℃ (other ambient temperatures available as an option).
- Ambient Humidity: Relative humidity below 90% (no condensation allowed).
- Altitude: Below 1,000 meters above sea level.
- Transmission Method: Pulley or coupling. However, for 2-pole motors with power of 45KW and above, only coupling transmission can be used.
- Rotation Direction: Bi-directional rotation. When the power supply phase sequence is consistent with the marking letters on the motor outlet terminal, the rotation direction is clockwise when facing the shaft extension end.
- Starting Method: Direct full-voltage starting or Y-△ starting.
Requirement: When installing the coupling or pulley, use the tapped hole at the shaft end for press-fitting installation. External force impact on the shaft end for installation is prohibited.
