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.
