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.
