MOTORS, BLOWERS & PUMPS

These brand-spanking new 12VDC motors are made to move automobile seats but are willing to change. They spin at approx 190 rpm, draw 1.5A no load, and stall at approx 25A. Threaded shaft is at a right angle and is 4-1/8" x 7/16". Shaft thread is non-standard, so treat it as a smooth shaft and mount pulley or gear with a setscrew. Measures 5-5/8" x 2-1/2" x 2-1/2" overall, not counting the shaft, and has power terminals opposite the gearbox with (2) 1/4" mounting holes opposite the shaft. Shaft Thread 7/16"-8 ACME thread w/M6x1 LH at end

Great little 12VDC oil-less diaphragm style air pump. For you techies out there it draws 40-300mA, 2.0 Litres/min, 350mm Hg max pressure. These are takeouts and in great condition but the leads on yours may vary in length or even be clipped off (Just solder to the connection points like the leads were.) Outlet port is 5/32". Overall size 2-3/4" x 1-1/16".

It's a head-spinning 10-Fer! Ten fans for ten bucks! These cute little 2" square 50mm muffin fans by Runda operate from 6-18VDC, and they’re rated at 18 Volts. They’re pretty gusty at 12VDC and run strong off a single 9-Volt battery. Each fan is 10.5mm and has (4) mounting holes in the corners. These are take-outs from unused equipment, and super clean. Great for group projects. Think: Scouts, classrooms.

1-1/2-9 VDC Gear Motor with a right angle gearbox and a 5/16" shaft. Shaft comes out of gear box back towards the motor. Overall size is 3" X 3-1/2" X 2-1/2" and weighs in at just over 1/2lb. Draws 250mA no load and 750mA full load. This bugger is one of the best motors we have had. Nominal voltage is 9 VDC (75 RPM) but will run off of just (1) AA battery with good torque and up to 12VDC for short periods.

Nifty device that takes maxi air and squeezes it down into a mini condition. The device is roughly 6-1/2"" long x 6" tall x 4" wide. It has a 10 ft. cord that plugs into an auto lighter socket: i.e. it runs on 12VDC @ 10 amps. Air output is via a 12" hose with a variety of valve adapters for tires, soccer balls, rubber rafts and the like. Complete with a 0-250 psi gauge. Which should be plenty of pressure to explode a weak bike tire or flimsy beach ball, so please be careful!

Nifty little display motor has (3) gears operating a 7-5/8” long pivoting plastic arm that swings to and fro a tad faster than twice a second. Mounted in a 4-3/4” x 3-5/8” x 1-7/8” white plastic box. All you add is a (1) D-cell battery, and something to wave. A good battery and it will go for hours and hours.

Attention robotics boffins: Here's a nice, powerful 12-24VDC Mabuchi brush motor with a gearbox and pulley attached. At its nominal 24DC, it spins 45rpm, draws 280mA no load, and stalls a 750mA. 7.5 in-lbs of torque and is rated for continuous duty. Has a 3/4" long x 5/16" flattened shaft with a 4-5/8" dia x 5/16" wide (3/16" ID) single-sheave pulley attached, with a matching O-ring. The gearbox measures 2-3/4" x 3" x 9/16". The motor measures 1-1/16"dia x 1-5/8" long and comes with 7" leads and a 2-pin Molex connector.

Sometimes a motor is just a nice, sturdy cylindrical motor made in Germany—like this 12VDC, 2800rpm beast, which stalls under 3V and has 2" of wire attached, ending in a (2)-pin connector. Has a spindle on both sides—(1) that looks like a threaded rod, and (1) that has a 1-2/4” dia plastic gear on it. Cylinder is approx. 3-1/2” long, plus the gear and bare spindle, which extends approx 1/2”.

The under-powered can opener we call it. This electric can opener takes (2) "AA" batteries but is as weak as the old "My dog ate my homework" excuse, so we suggest using it for parts instead of trying to open cans of soup with it. Or better yet, find a way to add another "AA" Battery. It has great parts either way. A six-way set of meshing gears and arms, a 3VDC 90mA/220mA motor that spins approx 5K (torqued out), and two-piece plastic case. Great for DIYers, hobbyists, small-motor heads or thin cans of soup. Not sold as a working kitchen can opener. 

Teacher Alert! At this price makes a great school project to show the inner gear workings of a gadget!

We’ve got a classic teardrop-shaped timing motor here. It spins 3 rpm clockwise, and measures 2-1/2" x 1-3/4" x 7/8” with a 1/8" x 7/16" flattened shaft. 120VAC with a pair of 10” leads. Motorola model 150-1485. Draws 4W. Put your imagination to work and build something that needs a motor like this.

This 20 GPM (gallons per minute) submersible fluid pump will shoot fluid approx (15) feet upward. Fits standard garden hose, Comes with (4) rubber feet and It even includes a brass barbed hose connector for 8mm hoses etc. Unit measures 7" x 5-1/4" x 4" with a 3” handle and a 15-goot power cord. It has a lifting handle on the top and a removable filter space for cleaning. It does not include a filter. Pump must be submerged 2x the pump height (aprox 13”). Operates on 120 volts at 105 watts.

Jarvis Says: Catalog mistakenly mentions tubing is included. Tubing is not included. Do not run pump dry.

This torquey take-out 6-24VDC (12VDC nominal) motor draws approx 250mA no load, stalls at 7.2A and spins approx 5700 rpm. Measures 2" x 1-13/32" with a 3/4" x 1/8" flattened shaft and may have a setscrew-mounted coupler that resembles a router bit. Has prewired leads. Mabuchi part no. RS-545SH.

This little 1.5-3VDC motor draws just 15mA no load, which means it's just the ticket for solar-cell applications. At 3VDC it spins approx 600 rpm and stalls at 125mA. Measures 1-1/8" long x 15/16" dia with a 5/16" long x 1/16" dia shaft and 3-1/2" leads.

This little black plastic fan and frame measures 2” square x 7/8” thick, and is a 12VDC 0.15 mA brushless model EFB0512HA. Has an air flow of 11.40cfm, and spins at 5500rpm. Able to operate from -10 to 70 degrees Celsius. Has a pair of 6” long red/black leads with a quick-disconnect.

Got lots of aquariums? This oil-free Hailea 115V air pump is strong enough to keep air flowing into your large or multiple aquariums, and its linear piston design ensures long life. It’s low-noise at <60dB (The manufacturer says low-noise, but trust us, you don't want this running in the bedroom.) and low-vibration, because fishes (and you) don’t go for those things. Draws 160W of power and puts out a continuous 5 cfm of free-flow air pressure (that’s 145 liters a minute) at 5 psi. Has an inlet port with a 0.571 OD barb for 13mm tubing, and a 0.466 OD barb for 10mm tubing; and an outlet port for M12 x 1.5 metric pipe. Unit measures approx 11-1/4” x 6-1/2” x 5” with finned aluminum heat-sink housing and rubber-cushion feet. Weighs 13 lbs.

Muffin fans, pay attention. You pick the "nice" 110 VAC 21W fan from Thermocool, measuring 4-3/4" square x 1-1/2" thick with an offset two-pin power connector, rated for 82-95 cfm and spinning at approx 2600 rpm, with five blades and 3/16" mounting holes at the corners (Mfr part # G12038HA1ST); or the "beastly" 110VAC 36W muffin fan from the same mfr, which blows up to 198 cfm at 2900 rpm and measures 6-3/4" x 6" tall x 2" thick with (2) power terminals on a removable shroud, 5 blades, 5/32" mounting holes on the corners plus a ground lug. Both UL.

Even this 7/8" x 2-1/8" Hennkwell ball bearing reversible gear motor is ball bearings. Fletch could have told you that. Operates from 6-24VDC (optimal being 24VDC, turning at 142 rpm). Item number PZ22GR9120R-084BBH. Has a (2)-shafted front shaft (6mm dia x 14mm length), and a rear shaft with a 2mm dia x 11.2mm length. Also has (4) front-threaded mounting holes and solder lug terminals. Made in Taiwan.

Here are the ins and outs of submersible pumps for your DIY fountain.These small electric pumps run on 24 VAC (For low energy consumption.) from the included wall outlet adapter, are rated for continuous duty, have (3) suction-cup feet, an adjustable flow control and both a straight and 90° 5/16" tubing adapter. This little pump is roughly 2-5/8" x 1.5" x 2-1/4", has a 6-ft power cord with an in-line switch, and pumps 70 gal/hr @ 1 ft lift. Plug it in and go with the flow. Indoor use only.
