Operating conditions | 8LSN |
|---|---|
Rating class, operating mode per EN 60034-1 | S1 - Continuous operation |
Ambient temperature during operation | -15°C to +40°C |
Reduction of nominal and stall current as well as nominal and stall torque at temperatures above 40°C | 10% per 10°C |
Max. ambient temperature during operation | +55°CContinuous operation of the servo motors at an ambient temperature of +40°C to max. +55°C is possible, but this results in premature aging. |
Reduction of nominal and stall current as well as nominal and stall torque at installation elevations starting at 1,000 m above sea level | 5% per 1000 m |
Max. installation elevationRequirements that go beyond this must be arranged with B&R. | 2000 m |
Max. flange temperature | 65°C |
Degree of protection per EN 60034-5 (IP code): Degree of protection with optional oil seal (DIN 3760): | IP64For IP64, the motor must be mounted with the mounting flange and this mounting must correspond at least to IP64 protection. Otherwise, only IP54 applies instead of IP64. IP65 |
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)With the IM 3031 type of construction and mounting arrangement (vertical, motor hanging on 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. |
