FAQs: Base Plates for Power System Applications
Base plates are structural supports for power systems like generators, which weigh between 500 kg to 10 tons and produce 50 to 2000 kW, as well as for inverter systems (10 to 500 kW), fuel cell stacks (80 to 250 kW), and battery systems (50 to 500 kw/h). They provide support and distribute loads ranging from 5 to 100 kkN and help floor systems with 50 to 95% isolation, vibrating close to 95% isolation. There are several types which include, generator skid base plates with thicknesses from 15 to 50 mm which support diesel or gas gensets with integrated isolators reducing 10 mm to 2 mm per second vibrations, inverter mounting plates for solar and wind power systems with a flatness tolerance of 0.020 inches over 1 to 3 meter dimensions, modular skid frames combining base plate and equipment rails for containerized power systems, and seismic-rated foundations which comply with IBC and IEEE 693 for earthquake zones.
Steel ASTM A36 is excellent for base plates due to its Weldability for fabricated assemblies. This base plate weighs ASTM A36, is quite rigid, producing a modulus of 200 gigapascals so it will not deflect more than 2mm under a load of 10 to 100kN. Coupled with a sufficiently high yield strength of 250 megapascals, it will support the weight of the equipment that is between 500 to 10,000 kilograms. Aluminum 6061-T6 is lighter with a nearly 60 percent weight reduction since it is intended for mobile and roof applications, which are quite conducive to corrosion, and the light weight allows for easy manoeuvrability. Additionally, it possesses a high thermal conductivity of 167 w/mk, which aids in applications with heat and positively affects the thermal performance of a structure. Cast iron GG-25 provides the most effective cast construction, which reduces the amplitude of 30 to 60 percent of the vibrations that are induced with steel resonance. Furthermore, it can thermally cycle with a high degree of dimensional stability between -20°C to +60°C, making it excellent for thermal break applications. Lastly, integrated ribs improve cast stiffness with no added welding.
For CNC machining, we have machines with fixed dimensions from 3 to 8 meters in length, 2 meters in width, and 1 to 2 meters in height, and are capable of machining the mounting surfaces in the flatness range of 0.010 to 0.030 inches on areas of 1 to 20 square meters. Face mills with a diameter of 100 to 300 mm make flat surfaces at a feed rate of 200 to 800 mm/min and a surface finish of Ra 3.2 to 6.3 microns. Coordinate drilling makes bolt patterns with a hole position accuracy of ±0.010 inches for mounting of 4 to 8 holes, flexibly drilled with a multi-spindle head. Surface grinding adds flatness within 0.005 inches, and a finish of Ra 0.8 to 1.6 microns on alignment surfaces. CNC plasma and laser cutting can profile cut from plates of 10 to 100 mm thickness. Robotic welding makes stiffening ribs and mounting rails with full penetration welds of AWS D1.1 standards.
For base plates we can achieve mounting surface flatness of 0.010 to 0.030 inches on equipment up to 5 meters, ensuring uniform equipment contact and load distribution, mounting hole positions of ±0.010 inches on bolt patterns of 500 to 3000 millimeters for alignment of equipment, perpendicularity of 0.020 inches between mounting surfaces and reference edges, parallelism of 0.015 inches between opposite faces for stacked assemblies, and overall ±0.050 for plates 1 to 5 meters in length.
Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.
Our base plates are processed under ISO 9001:2015 quality management systems and include traceable materials and dimensional verification. Components are compliant with NEMA standards for generator mounting and enclosures and are compatible with electromagnetic interference under IEC 61000. They also meet IEEE 693 seismic qualification standards for electrical equipment that endures peak ground acceleration between 0.5 to 1.5g, ASCE 7 standards for structural loading, and ISO 12944 corrosion protection standards C2 to C4 through to C4. Manufacturing included certification for materials and structural components that documented yield strength and chemical make-up, dimensional inspection reports, certified weld quality as per AWS D1.1, and structural calculations that validated deflection limits below L/500 under rated loads with target spacing.

For CNC machining base plates for generators that are 100 to 500 kilowatts or inverters that are 50 to 250 kilowatts with 1 to 3 meters in dimensions, the delivery time is between 6 to 10 weeks. Custom designs with more machining, complex shapes, or requiring seismic qualification testing take 8 to 14 weeks. You can get expedited machining on rapid prototypes, which is 4 to 5 weeks. However, for production orders above 100 plates, there is a 10 to 16 week setup time.
Absolutely. As a structural engineer, I specialize in designing and optimizing custom lightweight power system base plates with mass reduction ranging from 25-40% via Finite Element Analysis. I create integrated cable management plates with conduit channels and junction boxes, and modular universal multi-configurable equipment platforms. I also design and construct custom seismic-rated bases for critical facilities per IBC and IEEE 693 with 0.5-1.5G seismic peak ground acceleration, and specialty designs like load-rated custom rooftop mounting plates for wind load 1.5-3.0kPa, and marine plates with corrosion protection for offshore wind load. I also design containerized skid systems that integrate base plates with equipment rails, lifting points, and acoustic isolation that reduces sound transmission 15-25dB for urban installations.
Precision machining helps to keep the equipment position for flatness of 0.010 to 0.030 inches across mounting surfaces. This limits equipment realignment and helps to avoid increased friction and vibration. Overheated equipment can cause the bearings of a rotor to wear. This drops the service life of the rotor from 20,000 to 8,000 hours and causes the efficiency of the equipment to drop 2 to 5 percent. Positional accuracy of holes to within ±0.010 inches allows bolt patterns to align, which reduces assembly issues and allows even load distribution over the mounting points. Even the surface created for the mount helps to form a good base for the vibration isolators and helps to keep the isolation efficient 70 to 95 percent of the time. This drops the transmitted vibration from 50 to 2 millimeters per second RMS to below 5 millimeters per second, protecting the building structures.
Good structural welding with proper penetration for joints that meet AWS D1.1 standards can fail under the service load of 10 to 100 kilonewtons over a period of 20 to 30 years. Good service load under the life of the joint and proper shipment creates a good joint service life of 20 to 30 years with well-mounted vibration isolators. Rusting of structural elements poses a threat to the structures during exposed to environmental pressure.
Good manufacturing practice ensures that reliable support structures for the equipment are built for generator sets ranging from 50 to 2000 kilowatts, inverter systems from 10 to 500 kilowatts, and fuel cell stacks from 1 to 250 kilowatts, as well as for structural loads of 5 to 100 kilonewtons. These supports achieve 70 to 95 percent vibration isolation, and the deflection limits of the supports are between L/500 to L/1000 under rated loads. They are designed to serve for 20 to 30 years in industrial facilities, commercial buildings, data centers, installations of renewable energy, and mobile power systems.
