Availability: Retired

Out Of Stock

SKU: ROB-178



This powerful “550” motor is designed for 9-18V DC, but ideally used around 12V. At 12V the shaft speed is approximately 12000 RPM, so for most applications, a gearbox or reduction pulley system would be desired. The motor measures 38mm in diameter and 65mm long excluding the output shaft, which extends a further 9mm and measures 3.175mm in diameter.

To keep it in place, two M3 mounting holes are located on the front of motor. Large Solder tabs on the back allow wire to be firmly attached.
