Matters to be paid attention to when using motor
8-1 (Please lay the
motors carefully in transportation to avoid any serious damage to the motor
body or its electric
function because of collision.)
8-2 (Please use and storage motors
according to N0.2 item (Operating Conditions) in specification, or else
motor
characteristics would be affected.)
8-3 (Make arrangement to limit the storage
period to 6 months or less. Condensation of atmosphere must be avoided
in motor usage or opening the packaging of the
motor.)
8-4 (For proper operation. storage
and operating environment must not contain corrosive gases. For example H2S.
SO2.
NO2. CL2. etc. In addition storage environment
must not have materials that emit corrosive gases especially from
silicon. cyanic. formalin and phenol group. In
the mechanism or the set. existence of corrosive gases may cause no
rotation in motor.)
8-5 (Please don't stall the shaft for a
long time after powering.)
8-6 (There should be no sundries (such as
grain, fibre, hair, small tape, glue etc.) in the shaft end play.)
