Siemens Low Voltage Motors – Installation

The Siemens electric motor is easy to install and modify in every frame size. The terminal box is easy to access and the housing architecture allows adaptation to the most varied applications.

The terminal boxes can be swiveled in 90° steps, and the motor feet can be flexibly mounted depending on the motor version. An encoder, brake and external fan can be added with minimum effort. The flexible housing architecture results in a reduced variety of parts, simplifying inventory management.
