Big Blower
CJ calls this new 12VDC squirrel cage blower “insanely gusty,” if your looking to move some serious air. It’s 8 amps, and spins approx 2000 rpm. The cage is 6-1/4” dia x 2-3/4” and the motor is mounted on a 6-5/8” dia plate with 1/4” mounting holes and foam tape on the business end. The motor housing measures 3” dia x 2-7/8”. Normally CCW, but reversible.

Molon Motor, Free Fan
This 230VAC Molon gear motor spins 45 rpm, draws 340mA, no load, and stalls 450mA. Turns CCW with 7in/lb of torque. The motor side of the shaft is 3/16" dia x 3/4" long with a plastic 4-blade fan. The gearbox output is a 1/4" dia x 5/8" long flattened shaft with a cotter pin hole. Unit is 4-1/2" x 2-3/4" x 4-1/2" OA. Thermally protected, and made in the USA.

Small Johnson
But "pretty strong," the motor mavens say. This little 12-24VDC motor from Johnson spins between 5 and 10K rpms. At 12VDC it draws 160mA no load, at 24VDC it draws 180mA no load. Measures 2-1/4" long x 1-3/8" dia with a 1/8" dia x 5/16" shaft.

C-Frame AC Motors
C-frame or open frame motors are popular in household fan and blower applications, though we at American Science have heard countless other suggestions, ideas and pipe dreams. They run on household current (110 - 120VAC), and they do this for a long time if properly fan-cooled. Low maintenance bearings may be oilable, sealed or permanently oiled as in Oilite bushings. Square shaped like a "C", with coil wound around stack, they usually mount from pairs of holes through the stack. Our shaded pole, 2-pole motors come in several sizes and configurations. Stack thickness is a general indicator of strength, ie: thicker=stronger. All operate at approximately 2600 RPM. Some motors are double shafted, providing CW & CCW rotation. Rotation can be reversible or dual shafted. For the fridge, the bathroom fan, any where you need to blow hot air, get a cold shoulder or retro-fit your automatic fly swatter.

Fan/Heat Sink
It's a rare fan that only vents out the sides, but this Millennium Electronics MOTHR-1024-C, 12VDC, 60mA, 9-blade muffin fan does just that. The whisper quiet fan is mounted in a black aluminum heat sink 1-3/4" square x 3/8" thick. The (2) 1-1/2" leads end in a 2-pin connector.

Blade, No Fan
So build your own (see "Motors"). Our white-plastic 4-blade fan (blade only) is 6" dia OA, with a 2" dia x 7/8" thick hub with a 3/16" bore. Made for a clockwise rotation. Not pristine, but not used, either. Made in the USA.

3 VDC Stepper
It's interesting in itself, but what we really like about this 4-3/16" dia subtractive 5-color dichroic filter is its Nidec 3 VDC double-coil stepper motor, manufacturer's part #3258754010. It has a 4-pin ribbon lead, and a little driver circuit board with a 6-pin Molex connector. Approx 1-1/8" thick OA. Sorry, no hook-up sheet.

We Have So Many Fans
And even more fan blades. Choose a white-plastic 5-blade or a black-plastic 4-blade, each approx 4" across with a 3/16" bore. Designed for clockwise rotation. No motor. Just blades. (But nice little blades.)

Science Fare
Slightly larger than some of our hobby motors, this Mabuchi RS-365SH double-shaft motor is a good choice for science-fair projects. Its range is 6 VDC, 50 mA, 550 rpm to 24 VDC, 80 mA, 2,000 rpm. The 3/32" dia shaft extends 5/8" from the terminal end of the 1-1/2" x 1-1/16" dia motor, and 3/8" from the other end. It has (2) 5" leads.

Molon Mystery
Molon #LMO-6360-1 stepping motor of unknown voltage. Each step is 18° (20/rev). 2-5/16" dia. x 1-1/8" thick with a 1/4" dia. x 1-1/8" shaft. There is an easily removed, complicated mounting/coupling assembly on some of the motors but not on others.

Takeout Hitachis
Clone motors –– almost. The 24 VDC Hitachi stepper motors (both of which are labeled with Kodak’s part number 315871) are almost identical. Each has 1:5 gearboxes, (3) Hall–effect sensors, and 12 steps per revolution (without the gearbox). The motor cases are 1–3/4” thick x 3–5/8” dia. The 2–1/2” sq x 15/16” thick gearboxes terminate in 1” x 3/8” dia flattened shafts with mounted plastic cams. Each has a set of (7) and a set of (3) leads with Molex–type connectors. The only difference between the takeout motors is that one draws 3 amps, and the other draws 2.4 amps. Sorry, folks, that’s all we know.
