For this build we will require:

Video Guide:
Rotor - Super-Efficient Build Guide

If you intend to manufacture motors, you can follow our Stator & Motor build guide,  however you will need to double up this factory to produce 20 rotors per minute.




Part 1 – Foundations. 


To start off we shall be placing a grid, 8 wide and 13 foundations long. In the picture above you can see a white foundation in the 8th column along the 7th row. The reason for this is that that will be where the rotors are outputted to, for the stator & Motor guide. 

There is also two white foundations along the 1st column in the 7th and 10th row, these are to signify where I shall be running a conveyor belt under the factory. This build can be built more compact however we’ve maintained space to make this guide more understandable and easier to reproduce.


Part 2 – Smelter Placement.


You will want to keep the 1st row free for a Mk 2 manifold bus transporting 120 Iron ore per minute. First, we shall place the smelters along the front edge of the 2nd, 4th, 6th and 8th column. These should be placed directly in the centre of the foundation with equal space apart.


Next we will construct a merging manifold line by stacking mergers three high, two steps in front of each of the smelters the first three mergers will flow to the right, the fourth merger in the 8th column will face forwards.

You should now be able to connect elevators from the smelter up to the merger. Once done, connect all the mergers together with conveyors, upgrading to mk2 conveyors where necessary. You can also delete the stacks of mergers beneath the top manifold line.

As we are trying to run this factory at 100% clock-speed for the 10 rotors, you will now want to edit the fourth smelter’s clock-speed to 75%. The other 3 smelters will run at 100%.

At this point, your factory should now look something like this.



Part 3 – Placing The Iron Rod Constructor Line


At this point we need to build another manifold line, this time splitting the iron ingots between eight constructors. To get the right placement for the splitters, we shall first place the eight constructors. These should be placed in the centre of each column with the edge of the constructor along the front edge of the fifth row.

We can now place a splitting manifold line, to do so place a splitter directly two places behind each constructor input. All the splitters should flow to the left, with the exception of the splitter in the eighth column which will flow forwards, being fed by the last merger in-front of the fourth smelter.



Merging Line 1.


At this point we will be placing two merger lines against the constructor’s outputs. One line will go off to produce screws and the other will carry the already produced rods to the assemblers to become rotors.

So in-front of the constructors in the first three columns you will need mergers. The first merger will face forwards and will use an elevator to take the rods under the next line of constructors. The other two columns will have mergers flowing to the left to feed into this merger.

Next we shall then place a splitter in front of the 4th constructor. The left output from this splitter will head into our iron rods line.

Hopefully at this point your factory will look like this. 



Merging Line 2.


Next we shall place the merging line for the rods that are moving on to become screws. However, before we do so we need to place a merger immediately to the right of the splitter that we placed previously, this merger should also be facing the right direction. From here we shall combine the two free remaining outputs of the splitter, connecting them both to this merger. Once done, we shall place mergers in-front of the three remaining constructors. These will flow to the right, with the exception of the merger in the eighth column which will flow forwards. Note that the merger placed next to the splitter should also connect to the mergers we’ve just placed.

Before we move to the next section, we will once again cover clock-speeds. All constructors will be at 100% clock-speed with the exception of the last constructor in the eighth column which will be running at 50%.

At this point you should have 50 rods heading under the next foundation, and 62.5 rods heading on to become screws. Please remember if a conveyor is running over 60 items per minute, you will need a MK2 belt.



Part 4 - Screw Constructors.


With the rods being moved along the right-hand side of the factory to become screws. 
Place 7 constructors along the front edge of the 8th row, starting from the first column. Once done setup the splitter manifold line, again 2 places away from the constructors. As we’ve already done this several times in today’s guide, I wont cover how to do this, but if you’re still not sure on how to build a manifold check my guide out here.

Do note that the first merger in the eighth column will flow forward the rest should flow from right to left.

You should have set this second row of constructors all to screws by this point. The clock-speeds are as follows: Constructor 1-6, 100% clock-speed. Constructor 7, 25% under-clock. 



Part 5 – Assemblers.


Moving on, we will place 3 assemblers on the edge of the 11th row. We shall then place a double manifold laying one manifold holding screws, on top of the other manifold holding rods. Both lines will feed the assemblers allowing the manufacturing of rotors.

Next, run the output from the assemblers along to the right of the factory grid, not forgetting to use mergers so the rotors are all on one line. Here we shall place a container where they will store until we are ready to work on a motor factory which we cover here.

Do note as we are using manifolds the screws manifold line will need a MK3 conveyor as you will be transporting 250 screws per minute.

When it comes to the assemblers, you will be required to place an under-clock of 50% on one of them. The other two will be running at 100% clock-speed.

Once fully operational, you should now be able to produce 10 rotors per minute and is easily scale-able and very clean looking along you foot room to walk around the factory yourself.
