Datasheet

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 capability 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 350c. 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.
