Operating conditions | 8LVA |
---|---|
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 the nominal current and stall current at installation elevations over 1000 m above sea level | 10% per 1000 m |
Maximum installation elevation | 2000 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) 8LVA1 with and without oil seal: 8LVA2 / 8LVA3 without oil seal: 8LVA2 / 8LVA3 with oil seal: |
IP54The degrees of protection are only achieved if the power and signal connections are fully installed. For IP54, the motor must be mounted with the mounting flange and this mounting must correspond at least to IP54 protection. IP64 5) For IP64, the motor must be mounted with the mounting flange and this mounting must correspond at least to IP64 protection. IP65 5) |
Type of construction and mounting arrangement per EN 60034-7 (IM code) | Horizontal, motor shaft aligned horizontally (IM 3001) Vertical, motor standing on the machine (IM 3011) Vertical, motor hanging on the machine (IM 3031)The IM3031 type of construction and mounting arrangement (vertical, motor hanging on the machine) must be avoided since production fluids or oils, e.g. from a gearbox, can penetrate the motor and damage it. If this is not possible, it is mandatory to select the oil seal option and to ensure that no production fluids or oils get onto the seal. |
