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, and not to touch the weight when motor is rotating.
8-6 There should be no sundries (such as
grain, fibre, hair, small tape, glue etc.) in the shaft end play.
