Electric engine unit — Factorio Production Calculator
Electric engine unit is crafted in the assembling machine in 10 seconds, producing 1 per craft from 1 × Engine unit, 15 × Lubricant, 2 × Electronic circuit. At 60 per minute you need 20 assembling machines, and the chain behind it draws on 3 raw resources: heavy oil, iron ore, copper ore.
Production chain for 60 Electric engine unit / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Lubricant | 900 | 1.5 | Chemical plant |
| Iron plate | 660 | 35.2 | Furnace |
| Copper cable | 360 | 3 | Assembling machine |
| Copper plate | 180 | 9.6 | Furnace |
| Pipe | 120 | 2 | Assembling machine |
| Electronic circuit | 120 | 2 | Assembling machine |
| Electric engine unit | 60 | 20 | Assembling machine |
| Engine unit | 60 | 20 | Assembling machine |
| Steel plate | 60 | 16 | Furnace |
| Iron gear wheel | 60 | 1 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Heavy oil | 900 |
| Iron ore | 660 |
| Copper ore | 180 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Electric engine unit recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 1 | Engine unit × 1, Lubricant × 15, Electronic circuit × 2 |
What the whole chain needs
60 electric engine units per minute pulls in 9 intermediate products, and the whole tree comes to 110 machines across 3 machine types, fed by 3 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 900 per minute, which is 1 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.

FAQ
How many assembling machines do I need for 60 electric engine units per minute?
20 assembling machines. One at standard speed produces 3 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does electric engine unit take?
At 60/min the chain consumes 900 heavy oil per minute, 660 iron ore per minute, 180 copper ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is electric engine unit needed for science packs?
Not directly. It feeds Rocket silo and Power armor MK2, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
