Insulation Material Class; Surface; Shaft End, A-Side; Protective Device - Kollmorgen AKM Serie Manual Del Producto

Technical Description
16.2.4

Insulation material class

The motors come up to insulation material class F according to IEC 60085 (UL 1446
class F).
16.2.5

Surface

The motors are coated with polyester powder coating in matt black. This finish is not
resistant against solvents (e.g. trichlorethylene, nitro-thinners, or similar).
16.2.6

Shaft end, A-side

Power transmission is made through the cylindrical shaft end A, fit k6 (AKM1: h7) to EN
50347, with a locking thread but without a fitted-keyway.
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.111. The maximum values at rated speed you will find at the technical data.
Power take-off from the middle of the free end of the shaft allows a 10% increase in F
Axial force
When assembling pinions or wheels to the axis and use of e.g. angular gearheads axial
forces arise. The maximum values at rated speed you will find at the technical data.
Coupling
Double-coned collets have proved to be ideal zero-backlash coupling devices, combined,
if required, with metal bellows couplings.
16.2.7

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.
The motor can be delivered with a KTY 84-130 sensor optionally (see Connector Optio 1,
7 and 9 on page 40).
Provided that our preassembled feedback cables are used, the sensor is integrated into
the monitoring system of the digital servo amplifiers.
16.2.8

Vibration class

The motors are made to vibration class A according to EN 60034-14. For a speed range
of 600-3600 rpm and a shaft centre between 56-132mm, this means that the actual value
of the permitted vibration severity is 1.6mm/s.
