Abstract: A battery-powered motor may include an electric motor, a controller, and a housing. The electric motor may be wound to enable the battery-powered motor to achieve a non-limited motor maximum motor revolutions per minute (RPM) for at least one specified battery. The controlling current may include limiting current to the electric motor at lower RPMs, and limiting the current to prevent the RPM of the electric motor from exceeding a limited maximum motor RPM which is lower than the non-limited motor maximum RPM. The housing may enclose the electric motor and the controller and the specified battery. The housing may have a form factor to engage with a machine that engages with an internal combustion engine that has a maximum engine RPM that is approximately the same as the limited maximum motor RPM.
