4.1 Transport, storage and installation
Transport
z
Motors may only b e transported using a suitable means of conveyance and appropriate
hoists.
– Ensure secure fastening: the motors are partially equipped with transport eyelets that are
intended for secure fastening to hoists. They are only designed for the weight of the motor
and must not
n
be used if other components are mounted to the motor (weights: see
catalogue).
z
Ensure vibration-free transport of motors.
z
The motors must not be exposed to hard knocks and bumps.
Storage
location
z
Vibration-free
– If vibrations cannot be avoided, the rotor must be rotated in the bearings once a week.
z
Dry, non-aggressive atmosphere
z
Dust-free
z
Without sudden temperature changes
z
In the delivery state, all steel components have corrosion protection. Do not remove the
protection!
Check every three months and replace, if necessary.
Installation
z
Provide fixings which correspond to the design, weight and torque of the motor.
z
The foot and flange surfaces of the motor must be fitted evenly before the motor is fastened.
– Incorrect motor alignment reduces the service life o f the roller bearings and transmission
elements.
z
Couplings and other transmission elements must be fitted in accordance with the regulations.
– Impacts on shafts can cause bearing damage (Q Ch. 4.2).
z
Do not exceed the permissible range of ambient operating temperature (Q Ch. 3.1).
z
Humidity ≤ 85%, non-condensing
z
Vibration ≤ 2g / 20m/s
2
without resonance excitation
z
Fasten motor securely
z
Ensure that ventilation is not impeded
z
During operation, surfaces are hot, up to 140 °C! Ensure that guard is in place!
4.2 Assembly of built-on accessories
Follow these instructions carefully. Please note that the warranty and product liability will
become void in the event of impermissible alterations or modifications to the motors.
ƒ
For new motors, you may have to re move the corrosion protection from the shaft
ends and flanges. In this case, ensure that no solvent enters the bearings!
ƒ
The mounting dimensions are standard dimensions in accordance with IEC 34.
ƒ
Attach transmission elements:
– shocks and impacts must be avoided! They could destroy the motor.
– use the centre bore in the motor shaft in accordance with DIN 332, design D.
– tolerances of the shaft ends:
≤∅
50 mm: ISO k6,
> ∅
50 mm: ISO m6.
ƒ
Dismounting must only be carried out with an extracting device.
ƒ
When using belts for torque / power tra nsmission:
– check the belt tension
– observe the permissible radial forces specified in the catalogue.
