Abstract
The frequency converter for an electrical motor essentially consists of power part integrated in a common semiconductor component, of a component accommodating at least the intermediate circuit electronics and of a component accommodating the control and regulation electronics. The electrical connections from the semiconductor component of the power part to the intermediate circuit component and from the semiconductor component of the power part to the control and regulation component are formed by sheet metal connections which are positioned and mechanically connected to one another by way of a common cast body.
