Just add 1.5–6.0 volts of power and watch this efficient little motor “hum” at 7000–11,000 rpm. A very dramatic item to add to student experiments with circuitry. Also use this motor to teach motor operation and polarity or to spin small objects. You’ll find many uses for this little workhorse! Includes connecting wires with alligator clips. Optimum performance with 3.0–4.5 V.
