Overall it measures 3-1/2” x 2-3/4” x 2”. Has two 3/16” terminals on the motor side of the unit. Great motor and assembly!

Remember those old school vibration football games, or those fantastic days-of-yore vibrating beds in roadside motels? This is like that, just sized to today's pocket-held devices. It's a very small vibration motor (10mm dia x 2.5mm) that produces a pleasant buzz. Motor has 1-1/4" power leads, draws approx 60mA at 3VDC. Has 0.75g vibration amplitude. Self-adhesive pad on one face. No shaft.

Is a joy forever, and is also this right-angle, intermittent-duty, reversible gear motor, according to CJ, who has an eye for these things. This one is rated for 120VAC, spins at 35 rpm and draws 0.93 amp. Great for Halloween or other motion-displays. It’s open-framed and measures 3" x 4" x 2-1/2" with a 3/16" shaft flattened on both sides, with a threaded center for easy mounting. Has (3) leads and comes with a start capacitor.

Jackpot! A match made in heaven. We’ve combined our strongest little gear motor with its matching wall adapter for all your DIY needs. The reversable gear motor is 1-1/2-9 VDC with a right angle gearbox and a 5/16" shaft. 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. The included plug-in wall adapter is standard 120Vac input, 9 VDC output at 1 Amp through it’s 6’ cord. Simply snip off the plug on the adapter to reveal two wires. Then connect to the two terminals on the motor. Presto! (Consult an electrician if you have questions)

…with this nice little gear motor. Nominally rated for 24VDC and draws .2A with no load, this motor spins clockwise at 24RPM.

You pick: the 11VAC motor that spins 1 rpm CCW with a 3/4" long shaft with an attached 3/4" dia x 1/4" thick 16-tooth gear, 24-pitch and 20-degree pressure angle; or the 24VAC motor that spins 1 rpm CW and has an 8-tooth, 5/16" dia x 11/32" plastic gear, 32-pitch and 20-degree pressure angle.

That’s us, a breath of fresh air in the shopping atmosphere. Also, your source for these surplus Swiss-Air™ II Freshener Systems--one with a motion activator, and one without (you pick). Originally took cartridges that freshened the air with cherry, orange, berry, potpourri or other scents. Do they work? Might could, as they say in Nowth Car’lina, but we’re selling them for parts. The wall-mount cases measure 7-3/4" x 3-1/2" x 3-1/8” in cream plastic, with a cover that comes off to reveal a dandy 1.5V motor with a 5-blade fan, and terminals for a D cell battery. Motor is 1” dia x 1” long, shaft is 1/16” dia x 3/8” long, and fan blade is 2-3/8” dia.
