Abstract
An electric motor arrangement for a pump includes power electronics for control of the electric motor driving the pump. For cooling of the electric motor and/or the power electronics, media from a pump chamber of the pump casing flows through a suction-side connection, a coolant channel associated with the power electronics and/or of the electric motor, to a pressure-side connection of the pump. The flow in the coolant channel may be controlled by a thermostat valve.
