An electric motor on Wikipedia (151-13-41) converts electricity into rotating mechanic energy. It acts as a primary motion source for other devices that would need it.

Electric motors could be found in a large diversity of systems and usage, in industry or domestic domains. Many situations would lead us to use this tag on OSM, as to describe if a mechanical device requires electricity to run.
It's for instance relevant to use it in combination with man_made=pump.

Note that mechanical_driver=* should not be confused with actuator=* as the first is a primary energy source for a system while the last only commands it.

Hydropower generation sometimes involves pump for large scale water storage. Some power plants have pumps separated from turbines like in Veytaux, Switzerland where a 600 tons multi-stage centrifugal pump is located below a Pelton turbine, linked by a direct coupling (see this chart). The pump is driven by the generator used as an electric motor with electricity coming from transmission grid. When the pump s running, the Pelton turbine runs empty without water.
