Abstract
An electric motor with an add-on unit, such as a gearbox unit, encoder unit or controller unit, and disclosed whereby the electric motor and add-on unit can be firmly connected to each other. For a firm connection, a shrink ring is thermally shrunk on to the electric motor and add-on unit in the area of the joint so that the shrink ring covers the joint. A method is also disclosed for producing the connection, wherein a temperature difference is first created between the shrink ring on the one hand and the electric motor as well as add-on unit on the other hand, whereby furthermore the temperature of the shrink ring is greater than the temperature of the electric motor and add-on unit and whereby the components are then joined together and held so that the shrink ring shrinks on to the electric motor and add-on unit.
