Reminder that this chapter will be very technical, so if you're easily confused please watch a video on how electric motors work first. Also I'm not an electrical engineer so please take all of the information I will say about the electric motor with a grain of salt.
Anywho, Thanks for reading and enjoy the chapter!
As soon as Nirra returned home, she got straight to work on a groundbreaking invention that would change the world if she shared its secrets. The electric motor
If she were able to make a basic and functional electric motor, then manufacturing firearms would be a whole lot easier. Especially when she can just drill solid steel rods to make a barrel and use the drill to start milling steel blocks to shape them into more complex parts for self-loading firearms.
Nirra only has the basic knowledge of how an electric motor works due to the times that the steel milling machine she used extensively in her past life broke and she had to fix it on her own.
Nirra got to work and started scribbling down plans. She already has the power supply, which is lightning magic. The electric motor works on the principles of electromagnets, which turn ordinary metals like copper into working magnets by using electricity, and that opposite poles of a magnet attract while the same poles oppose one another.
With a bit of thinking and headscratching later. She deduced that she needed two curved pieces of lodestone that would act as the stator, which is the part of the electric motor that stays still, while the rotor, which comprises several copper rods, would spin using an electric circuit by means of lightning magic.
First were the pieces where the copper bar would be bent around, called the armature. The armature, when electricity is fed through it, would become an electromagnet. So she needed a casing that would help shape the copper bar, made out of a material that does not let electricity pass through. Her eyes had fallen upon the wood storage as an idea popped into her head. She remembered that wood is a natural insulator and would help keep the rods from touching each other and keep them in shape. Obviously, it's not as ideal as something like aluminum, but in her mind, it should work. She grabbed a piece of wood and started carving it into the shape that she wanted. After she was done, the wooden piece looked like a very thick cylindrical cogwheel with 20 teeth about the size of her hand.
Next, she grabbed two pieces of loadstone and measured where their north and south poles were located. She then used the grind stone to grind down the pieces she had into two curved pieces, which were a bit larger than the wooden piece she made, leaving a small gap so that the stator and rotor would not make contact.
Next, she prepared to cast the remaining parts she needed. This included the communtator, which will transmit electricity from her hands directly into the copper bar and switch the poles of the electromagnet to keep it spinning. The commutator looks like a smaller version of the armature, but it's made out of copper sheets that are curved outward. She used clay to mold the pieces and set them to dry in the furnace. Next were the copper bars that would produce the electromagnet needed to rotate the armature, or rotor. She just used a piece of wood shaped like a boxy "u." She made 10 of these and measured them so they would fit snugly with the armature. The last component she needed was the brushes that would make contact with the commutator, which would make electricity flow through it and into the armature. She used a small chip of wood to cast it and will assemble it further later using a small case and springs.
Once done, she placed it inside a box, filled it with sand, and started melting copper. After the copper melted, she took out the molds for the components and left the cavity open. Then she poured in the molten copper and waited for it to cool.
Once cooled, she sanded down the components so that they would fit tightly with one another and gathered all the things required for final assembly. First, she inserted the copper u-shaped bars around the spaces of the stator. Then she attached the commutator to the armature by sliding a metal bar through the center of the entire motor. She then fixed the two pieces of the stator to a wooden base using nails and then mounted the rotor assembly between the two halves of the stator and sighed in relief that her measurements were correct and left a small bit of space between the stator and the rotor.
Finally, she completed the brushes by adding a small spring to them she then attached them in a way so that they would be in contact with the commutator.
Nirra's improvised and crudely made electric motor was now finished; now all she needed to do was test it by feeding electricity into the brushes.
"Please work..." She mumbled and prayed that it would work. She then made final checks to see if everything that she did was correct and touched the two brushes with her fingers and channeled a small amount of lightning mana into them.
Her heart sank when the rotor didn't spin, and she started to feel anxious as she pumped a bit more lightning mana into it, but still it would not spin.
Nirra examined it while still touching the two brushes and noticed that the brushes were in contact with four of the curved copper sheets, which meant two electric magnets were being made. Which in turn contradicted one another and prevented the rotor from spinning.
So, she briefly took her finger off one of the brushes and rotated the commutator slowly so that only two of the sheets were in contact with the brushes.
Her hand went back to its original position and started flowing lightning mana back into the system. Her eyes widened as she heared a low humm and the rotor started spinning at an estimated 100 rpm. As she added more mana, it started to go faster and topped off at 1,500 rpm. More than enough for her needs of steel milling and bore drilling. The design may be crude, but an electric motor spins faster based on how much electricity is fed into it. With lightning magic, and if she had the right materials, she would have an electric motor spinning at 6,000 rotations per minute.
She let her fingers out of it and jumped in joy as her crudely made electric motor came to life. Now she just needed to forge the drill bits so she could get to work on the single-action revolver.
