An electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors work through the interaction between the motor's own magnetic field and an electric current flowing in a wire winding, which generates a Lorentz force that appears as torque on the motor's shaft. An electric generator is mechanically the same kind of machine run in reverse, converting mechanical energy into electrical energy instead.

Invented By: Moritz von Jacobi, Article body
After many other more or less successful attempts with relatively weak rotating and reciprocating apparatus German-Russian Moritz von Jacobi created the first real useful rotating electric motor in May 1834.
Invented By: Thomas Davenport, Article body
Following Sturgeon's work, a commutator-type direct-current electric motor was built by American inventors Thomas Davenport and Emily Davenport, which he patented in 1837.
Invented By: Nikola Tesla, Article body
Possible industrial development was envisioned by Nikola Tesla, who invented independently his induction motor in 1887 and obtained a patent in May 1888.

While a top-loading washing machine could use a universal motor or DC brushless motor, it is conventional for top-loading washing machines to use more expensive, heavy, and potentially more electrically efficient and reliable induction motors.
