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.
