9. Cautions and matters
9-1 Warnings:
In a motor near the end its life, or under breakdown conditions, short circuits
can develop between commutator segments. Uncontrolled voltage may then leak into
the power source circuit. Motors may overheat or fail if run continuously with
its rotor locked condition or under excessive loads.
9-2
Destructive atmospheres: Do not
use and store the motor in the corrosive gas atmosphere (H2S, SO2,
NO2, Cl2, etc.), or substances that can emit toxic gases,
such as organic silicon, cyanide, formalin, or phenol compounds. The motor may
get serious damages.
9-3
Condensation: Condensation on
the electrical circuits can destroy the motor or control circuits. Monitor the
environment and undertake measures to prevent condensation, such as installing
condensation sensors to cut power when necessary.
9-4 Some
particular plastic materials can crack and fail after exposure to motor bearing
oil. Perform test the motor in/on the subassembly to check the influence of the
oiled plastic parts.
9-5
Avoid connecting a serial resistor to the motor if at all possible, as this can
negatively affect reliability. If this is unavoidable, keep resistance as low as
possible and test thoroughly for reliability before using.
9-6
When testing for UL, CSA or other safely standards, apply for approval for the
entire subassembly.
9-7
Do not store motors under conditions of extreme temperatures or high humidity,
or for longer than six months even room conditions. When removing out of
packaging after storage, take precautions to prevent condensation.
9-8
Please consults us in advance when design considerations call for forcefully
stalling the motor using a short circuit at the terminal or reverse voltage.
Such operations can shorten product life.
