42. Rotor and shaft
The squirrel cage on all motors is cast from aluminium. Motors in normal design are
supplied with a free shaft end. On request, any motor can likewise be supplied with
two free shaft ends. Motors of all sizes are generally equipped with two equal ball
bearings of the series 62 or 63. From size 200 upwards, it is possible to use roller
bearings in order to achieve higher radial forces.
43. Winding insulation
All motors are insulated to insulation class F. The thermal design of the motors is
made to insulation class B. The motors are suitable for an operation at a frequency-
converter. All motors are ready for Frequency Converter.
44. Full protection against overheating
On request, three or six temperature probes connected in series can be installed
(either one or two probes per phase). Supply lines are routed into the terminal box
and laid on to a special connector strip. The temperature probes (PTC) have a
positive temperature co-efficient and trigger at a winding temperature of 150° C. It is
also possible to install bi-metal temperature probes (Klixon as winding protection).
45. Installation
The electrical connection and maintenance of an electric drive may only be
carried out by qualified electrical personnel, who are conversant with the
relevant regulations. Similarly, the applicable accident prevention regulations
are to be adhered to.
Every motor is dispatched only after the specifications on the order have been
checked, and a trial run has been carried out. Until installed, the motor is to be stored
dry and in the same way as the mounting position. For trouble free functioning,
proper installation and operation is essential.
The motor is to be installed according to its mounting position on an even and
vibration-free base. The shaft extensions up to 50 mm 0 have tolerances conforming
to ISO k6 and above to ISO m6. Before fitting, the rusts inhibitor must be removed
from the shaft end, however, care must be exercised to ensure that no solvent
penetrate into the bearing. The motor shaft end has been provided with a center and
a tapped hole, according to the DIN specification 332 type D, which can be used to
pull on the transmission elements without exerting harmful forces on the motor
bearings.
Hammer blows and jolts are to be avoided at all times! The permissible overhung
loads shown in the catalogue may not be exceeded. They are valid for force acting at
