Powerful Robotics DC Gearmotors

2732-0141-2434-16 DC Gear Motors CLICK TO ORDER

Powerful DC gearmotor custom made for Diebold by Igarashi Motor Sales USA, based on the N2732 27mm motor core and a 33mm diameter gearhead (33GN2732 series). Amazingly powerful for such a small motor, the gear ratio provides very high torque. Exact data is not known, but measurements show it seems to a ~9VDC motor at 0.13A (no load, ~100RPM) and runs down to 5VDC (at 0.08A (no load, ~50RPM), and up to 12VDC at 0.28A (no load) with no difficulty. Fully loaded mechanically, the current is roughly double. The drive shaft is a flatted 5mm steel shaft. See full dimensions HERE. They are excellent for all kinds of electromechanical devices, with enough rest friction to allow the motor to act as a brake on the drive shaft. Tapped holes (3 x 3mm) on the gearhead face ends of the motor for attachment. Fully reversible, with all leads floating, it has a 2mm mating connector, and the Tyco pc mounting 2mm connector is INCLUDED. Like all brush DC motors, some L/C filtering is useful to prevent interference with other parts of the circuit. New and unused, ready for your application!

Easy to use Sanyo Power Amp Modules make it easy to build all kinds of Audio Amps!

STK4164MK2 STK4174MK2

We have several module types, and useful parts to go with them! The STK4164M2 is good for Stereo 35W systems (2 x 35W amps), the STK4174MK2 for 40W systems. These use split supplies, and have no output cap, very nice designs, and easy to work with and heatsink. Great to boost that iPod to room level, or as guitar and vocal amps or for creating Dolby 5.1 or 7.1 systems. These support a speaker muting relay to eliminate turn-on pops and crackles. Work with 8 or 4 ohm loads, and can be run at less power with a lower supply voltage. We have data and applications info available right here, wahoo!.
