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.
