6V-12V MICRO METAL
GEARMOTORS
ServoCity introduces a new line of micro metal gearmotors. Although these tiny gearmotors have a
footprint comparable to a micro-size servo and tip the
scales at only 0.3 oz, they are incredibly powerful.
All-metal gears ensure the motor will hold up in harsh
applications. The extremely versatile gearmotor case (sold
separately) provides protection for the gears and offers
numerous mounting options to fit a variety of custom
applications. It also allows the motor to be easily bolted to
other Actobotics™ components.
These micro gearmotors have a 3 mm D-shaft that
protrudes from the gearbox case. ServoCity has several
compatible accessories including pinion gears, hubs, and
couplers that attach directly to the shaft. There are nine
different RPMs to choose from. Pricing is US$9.99 each.
CHANNEL MOUNT
GEARBOX
The SPG785A-CM servo power gearbox also from ServoCity utilizes the Hitec HS-785HB sail winch
servo (included) to create a high-torque servo power
gearbox. The stock Hitec servo can rotate several turns in
factory form (approximately four turns on most Tx/Rx
systems; up to eight
turns with a
650-2,350 usec
signal).
When the
servo is installed
into the gearbox,
the total amount of
rotation is decreased by
the ratio selected, but the torque
and precision are increased by the
ratio. The lower the gear ratio, the more
precision and torque it will provide, but the speed and
amount of rotation will be decreased. By incorporating
threaded side mounts, users can
easily attach these servo gearboxes
to numerous Actobotics products
(including tubing and channel),
making it easier than ever to
incorporate a servo power gearbox
into a custom pan & tilt, mechanical
device, or robotic structure.
Five different gear ratios are
available in order to find the right
balance between torque and
rotation. Positioning feedback
remains since the servo is
completely stock and unmodified in
any way. The SPG785A-CM can
handle tremendous side loads with
the dual ABEC- 5 precision ball
bearings which support the
hardened 1/2" stainless steel hollow
shaft. The hollow shaft has a .382"
inner diameter to allow wires from
cameras, sensors, or other devices
to not tangle during multi-turn
