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.
