This 1.46″ x 0.79″ x 0.79″ gearmotor is a brushed DC motor with 65: 1 metal gearbox that has the power to deliver both speed and torque. These units have a 0.276″-long, 4 mm-diameter D-shaped output shaft.
This gearmotor is a miniature (0.94″ x 0.39″ x 0.47″), high-quality, low-current motor with 150.58: 1 metal gearbox, similar to Sanyo s popular 12 mm gearmotors. These units have a 0.365″-long, 3 mm-diameter D-shaped output shaft.
This NEMA 23 size bipolar stepping motor has a 1.8 Degree step angle (200 steps/revolution). Each phase draws 2A at 3.2V, allowing for a holding torque of 9kg-cm (125 oz-in).
This sub micro size servo motor has dimensions of 23 x 11 x 29mm. The operating voltage for this motor ranges between 4.8 to 6V with a maximum rotation of roughly 120 degrees. This servo motor comes with the servo horns and related hardware components.
This motor driver shield can drive up to 4 DC motor with 2 servo motors or 2 stepper motors with 2 servo motors. This motor driver shield uses 2x L293D motor controller chip with a 74HC595 shift register for all of its functions.
