cycle without the permissible temperature being exceeded.
The equipment is powered down in the no–load interval.
Overload factor = 2
Duty cycle = 1 min
Duration = 25 % of the duty cycle

A generally valid statement cannot be made about the lifetime
as a result of the various possible applications and the result-
ing load types as well as varying ambient conditions.
Factors which influence the lifetime include:
S
Duty types from continuous operation with one direction of
rotation up to extreme start/stop operation with load levels
from partial load up to full load and significant surge load-
ing.
S
Forced rotation accelerations or delays from the outside.
S
External mechanical loads in the form of a vibration and
shock.
