E fit be 1 - 20 sentences. Context: <response>: ```The first commutator DC electric motor wey fit turn machinery na British scientist William Sturgeon invent for 1832. After Sturgeon work, American inventor Thomas Davenport build commutator-type direct-current electric motor wey dem wan use for commercial purposes, and he patent am for 1837. The motors dey run reach 600 revolutions per minute, and dem dey power machine tools and printing press. Because of the high cost of primary battery power, the motors no sell well commercially and Davenport go bankrupt. Plenty inventors follow Sturgeon for development of DC motors but all of dem face the same battery power cost wahala. No electricity distribution dey available that time. Like Sturgeon motor, no practical commercial market dey for these motors.```
