Caution: The consumption current described above is the value during normal operations.An approximately threefold inrush current occurs during rotation startup.Short circuit between terminals may occur due to end of motor life or short circuit between commutator slits by specific operatingenvironment and condition. In order to prevent circuit burnout, please take protective measures such as using fuses.

DC Brushless Motor & Gear

Circuit protectionThis motor is not equipped with a circuit for protection against overvoltage and connection to terminals at the incorrect polarity. Be careful not to apply surge voltages that exceed the rated voltage and not to connect to the incorrect polarity.

This motor is equipped with an IC inside its casing. When the drive IC reaches a predefined temperature,the motor power shuts down automatically. There is no guarantee that a power motor having been shutdown due to temperature will be reusable.

If the motor locks up, the motor power will shut down within a predefined time. The motor will restart upon power-up.

Precautions

1. When selecting a tube, the customer should perform a verification test to verify the chemical suitability according to the usage environment and

　the intended application.

2. Regardless of the pump tube type, the phenomenon of peeling from inside of the tube starts with small amounts.

3. This product was not designed for medical use. Do not use for medical applications.

4. This product is not waterproof. If using in water-filled environments, design to protect against water.

5. Numerical data listed in this catalog reflect conditions measured over short periods of time. Their accuracy for long-term use is not assured.

6. There is a tendency for the flow rate to increase until the tube becomes acclimated, and even among the same model,

　different lots may have different flow rates within the specified tolerances. Also, the rotating speed of the DC motor may fluctuate

　depending on the load conditions and changes in the motor temperature. During the design stage, be sure to select a motor with ample capacity.
