1MT0013 series motors are supplied with the ball bearing as standard. These bearings are either of the sealed or re-greaseable type.
For FS80 ~ 160, the floating bearings are assembled; for FS180 ~355, floating bearing at DE, and fixed bearing at NDE assembled.
The standard bearing can endure a maximum cantilever force, the increased cantilever bearing design (Option code: L22) should be considered.
As standard, FS80 ~ 250 motors are not with regreasing device, but re-greasing device (Option code: L23) can be configured for FS160~250. FS280~355 motors with re-greaseable bearing and regreasing device are configured as standard.
For permanent lubrication, the bearing grease lifetime is matched to the bearing lifetime. This can, however, only be achieved if the motor is operated in accordance with the catalog specifications.
For motors which can be regreased at defined regreasing intervals, the bearing lifetime can be extended and/or unfavorable factors such as temperature, mounting conditions, speed, bearing size and mechanical load can be compensated.
Beide motors rated output powers means that the motor runs under continuous duty S1 (IEC 60034 – 1) operation when operated at ambient temperature from -15 ºC to 40 ºC and at altitudes of up to 1000m above sea level.
IEC 60034-1 differentiates between Category A (combination of voltage deviation ±5 % and frequency deviation ±2 %) and Category B (combination of voltage deviation %) and Category B (combinationof voltage deviation ±10 % and frequency deviation +3 % / -5 %) for voltage and frequency fluctuations. The motors can supply their rated torque in both Category A and B. In Category A, the temperature rise is approximately 10K higher than during normal operation.
