Starter motors are extremely handy items of engineering. As a substitute of getting to make use of a hand crank to start out your automotive, you possibly can simply flip a key or press a button, and voilà, the engine begins. However how does a starter work? Due to this practice see-through starter motor constructed by the Warped YouTube channel, we will see for ourselves.

Utilizing a 3D printer, Warped is ready to replicate the physique of a starter motor for a Kohler turbo-diesel engine. The insides of the motor are moved from the unique casing to the clear physique, giving us an uninterrupted take a look at all the inside workings.

From there, we will see the principle motor meeting, which makes use of completely secured magnets to spin a centrally mounted copper coil. When electrical energy is launched, the motor spins, whereas a solenoid connected to the highest of the motor engages a lever that pushes the starter gear ahead, permitting it to make contact with the flywheel. 

The slow-motion digicam provides us a wonderful view of all of the starter’s features as they occur. Sadly the torque breaks off a bit of the 3D-printer plastic physique, however as a concession, we get an uninterrupted view of the starter gear because it reaches out and spins the flywheel. 

Warped’s 3D-printed physique cannot deal with spinning the entire engine, so it is finally swapped out for a traditional starter motor. The channel finally tries operating the starter motor with the flywheel already spinning, displaying what would occur if you happen to tried to start out a automotive that is already operating. Unsurprisingly, it ends in a bunch of metallic shavings flying all over the place.
