These are a pair of right angle, hobby gearmotors from DAGU. These gearmotors are the same ones utilized in the Magician Chassis and RedBot Kit and offer a cheap and easy to use setup to get your wheels turning. Due to these gear motors being at a right angle, you will also be able to track and control the rotation of your wheels!
Solenoids are basically electromagnets: they are made of a big coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull from one end.
This two-part aluminum assembly mounts directly to 4 mm diameter motor output shafts like those on our 25D mm gearmotors and allows you to drive most scooter, skateboard, inline skate, and other common wheels that are compatible with popular 608 ball bearings.
This compact expansion board plugs directly into the GPIO header on a Raspberry Pi B+, A+, or Pi 2 and provides an easy and low-cost solution for driving a pair of small brushed DC motors. Its integrated DRV8835 dual motor driver allows it to operate from 1.5 V to 11 V, making it a great control option for low-voltage motors.
This compact bracket enables convenient mounting of popular, Sanyo-style micro metal gearmotors. The black plastic bracket encloses the otherwise exposed gears, and the mounting tabs capture the nuts for easy installation. The brackets are sold in pairs, and each bracket comes with two #2 screws and two nuts.
These white plastic wheels have rubber tires measuring 42 mm (1.65?) in diameter and press-fit onto the 3mm D output shafts on many of our motors, including our micro metal gearmotors and our plastic gearmotors with 3mm D-shafts. Teeth on the hub optionally allow a reflectance sensor to be used for encoder feedback. These wheels are sold in pairs.
These white plastic wheels press-fit onto the 3mm D shafts on many of our motors, including our micro metal gearmotors and our mini plastic gearmotors, to make a nice drive solution for small robots. The wheels have silicone tires and measure 60 mm (2.36?) in diameter. Two additional mounting holes for 4-40 screws make it possible to use the wheel with several of our universal mounting hubs.
This small NEMA 8-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 600 mA at 3.9 V, allowing for a holding torque of 180 g-cm (2.5 oz-in). With a weight of 60 g, this is one of the smallest stepper motors we carry.
The first in Tamiya’s “high efficiency” series, the planetary gearbox features two 4:1 and two 5:1 stages that can be combined in any way you like—you can even combine two kits to get really huge gear ratios. The output is always conveniently on the same axis as the motor shaft. Available gear ratios are 4:1, 5:1, 16:1, 20:1, 25:1, 80:1, 100:1, and 400:1.
