Chapter 4 • Installation conditions
Before every commissioning procedure, the motor must be checked by qualified personnel. The check must include
the proper condition in terms of mounting and installation, the installation conditions and safe operation.
Operating conditions
Rating class, operating mode per EN 60034-1
S1 - Continuous operation
Ambient temperature during operation
5°C to 40°C
1)
Relative humidity during operation
5 to 95%, non-condensing
Maximum ambient temperature during operation
40°C
1)
Reduction of the nominal current and stall current at temperatures above 40°C 5% per 5°C
Maximum installation elevation
1000 m above sea level
2)
Reduction of rated and stall current at installation elevations
Starting at 1000 m above sea level
5% per 1000 m
EN 60034-5 protection (IP code)
With oil seal option
IP54
IP65
Type of construction and mounting arrangement per EN 60034-7 (IM code)
Horizontal (IM3001)
Vertical, motor hangs on the machine (IM3011)
3)
Vertical, motor stands on the machine (IM3031)
1)
Continuous operation of the servo motors at an ambient temperature of 40°C to max. 45°C is possible, but this results in premature aging.
2)
Requirements that go beyond this must be arranged with B&R.
3)
With the IM3011 type of construction and installation (vertical, motor hangs on the machine) there is a risk that production fluids or oils will penetrate the
motor on the flange side. Motors or motor-gearbox combinations that should be used in this type of installation must therefore have at least IP65 protection
on the flange side.
1 Installation and cooling
Ensure unobstructed air circulation and cooling so that no heat accumulation can build up on the motor.
Attach the motor with the
motor flange
(1), which also serves as a
cooling surface
, directly on the machine.
The following points must be observed:
•
The opposite side of the mounting flange is not permitted to be thermally insulated. Heat from the motor
must be allowed to dissipate sufficiently.
•
Air circulation must not be impeded. There must be sufficient cooling air on the motor housing.
•
Exceeding the specified maximum values for motor temperature is not permitted.
It is important to note the following:
•
Power or heat from the motors is dissipated via the mounting flange and surface of the motor housing.
•
The motor can heat up due to external heat sources.
