Operating conditions | 8LWA |
|---|---|
Rating class, operating mode per EN 60034-1 | S1 - Continuous operation |
Ambient temperature during operation | -15°C to +40°C |
Maximum ambient temperature during operation | +50°CContinuous operation at an ambient temperature of +40°C to max. +50°C is possible, but this results in premature aging. |
Relative humidity during operation | 5 to 95%, non-condensing |
Reduction of the nominal current and stall current at temperatures above 40°C | 5% per 5°C |
Reduction of rated and stall current at installation elevations Starting at 1000 m above sea level | 5% per 1000 m |
Maximum installation elevation | 4000 mRequirements that go beyond this must be arranged with B&R. |
Max. flange temperature | 65°C |
Degree of protection per EN 60034-5 (IP code) The degrees of protection are only achieved if the power and signal connections are fully installed. - Without oil seal - With oil seal |
IP64 IP65 |
Type of construction and mounting arrangement per EN 60034-7 (IM code) | Horizontal (IM3001) Vertical, motor attached to the machine (IM 3011)With the IM 3011 type of construction and mounting arrangement (vertical, motor attached to the machine), there is a risk of production fluids or oils penetrating the motor on the flange side. Motors or motor-gearbox combinations that should be used with this mounting arrangement must therefore have at least IP65 protection on the flange side. Vertical, motor stands on the machine (IM3031) |
