Building on its decades of experience and expertise in the field of explosion protection, Siemens has continuously developed its existing explosion-proof motor landscape to create an integrated platform covering the protection type spectrum for zone 1 in Ex db eb (0.25-460 kW) and Ex eb (0.25-165 kW), zone 2 in Ex tb (0.09-200kW) and zone 2 in Ex tc (0.09-200kW. Due to the standardized underlying design concept, the universal principles of the low-voltage standard motors also apply to the certified motor variants, meaning that less effort is involved in planning, integration, storage and spare part stocking as well as servicing. Short delivery times and the elimination of project-specific system tests for variable-speed operation with frequency converters from the Sinamics family make for substantially faster project implementation. In addition, all the important global, country and industry-specific certificates are already available. The consistent use of standard tools and processes for low-voltage motors makes for far simpler planning, engineering, procurement, integration, commissioning as well as servicing and operation. All the Simotics XP motors comply with the requirements of efficiency class IE3, resulting in exceptionally low operating costs. Due to the flexible modular system used, the overall platform provides an ideal solution both for Original Equipment Manufacturers (OEMs) and for project business.
Additional optimization potential can be realized through the use of digital twins. This involves using data from 3D modeling and Finite Element Method (FEM) simulations over the whole of the life cycle to reduce the work involved in design, dimensioning and commissioning, and also for later modernization.
The data matrix code applied to the motor, which is used to store individual technical data, certificates and spare parts lists for the relevant motor, allows the information to be conveniently displayed in full using the Simotics Digital Data App. This simplifies both commissioning and spare part management, as well as lending the whole plant far greater transparency.
With its new generation of Simotics XP motors, Siemens has provided a simpler and faster way to implement projects and ensure optimum explosion protection.
