12.2.3 Protection class
Standard Motor Protection class
VLM2, VLM3 IP40
12.2.4 Insulation material class
The motors come up to insulation material class F according to IEC 60085 (UL 1446
class F).
12.2.5 Surface
The motors are coated in blue. This finish is not resistant against solvents (e.g. trichloret-
hylene, nitro-thinners, or similar).
12.2.6 Shaft end, A-side
Power transmission is made through the cylindrical shaft end A. Bearing life is calculated
with 20.000 operating hours.
Radial force
If the motors drive via pinions or toothed belts, then high radial forces will occur. The per-
missible values at the end of the shaft may be read from the diagrams in chapter "Dra-
wings" from p.68.
Axial force
When assembling pinions or wheels to the axis and use of e.g. angular gearheads axial
forces arise. The permissible values at the end of the shaft may be read from the dia-
grams in chapter "Drawings" from p.68.
Coupling
Double-coned collets have proved to be ideal zero-backlash coupling devices, combined,
if required, with metal bellows couplings.
12.2.7 Protective device
The standard version of each motor is fitted with an electrically isolated PTC (rated tem-
perature 155°C
±
5%). The PTC does not provide any protection against short, heavy
overloading.
Provided that our preassembled feedback cables are used, the sensor is integrated into
the monitoring system of the digital servo amplifiers.
