Caution and Matters
8 -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.
8-2
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.
8-3
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.
8-4 Be
aware of the following factors and perform necessary tests to
check a motor’s ability to adopt with your mechanism and
applications: Motor life, electric noise, mechanical noise,
vibration, static-electrical noise resistance, power-source
noise resistance, drift of rpm, electrical resonance between
control circuit and motor, mechanical resonance between
subassembly and motor malfunction due to motor noise,
electrical magnetic interference, malfunction due to magnetic
flux leakage, destruction due to lightning-related power
surge, grounding.
8-5 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.
8-6 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.
8-7 When testing
for UL, CSA or other safely standards, apply for approval for
the entire subassembly.
8-8 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.
8-9 Connections:
Complete soldering operations within three seconds to prevent
damage to leads and terminals. Make sure that the soldering
tip does not exceed 350°C. Be gentle with terminals; dents or
pressure on them can lock up the motor.
8-10 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.
