The motor drive system has innovative power, motor control and drives solutions that reduce energy consumption. They deliver greater efficiency with many advanced approaches to switch supplies – all ultimately reducing the carbon footprint. The motor drive system also boosts a manufacturer’s competitive edge and time-to-profit.
The machinery market covers several industrial applications such as food and beverage manufacturing machinery, semiconductor manufacturing machinery, sawmill and woodworking machinery, machinery for making paper and paper products, printing and binding machinery and equipment, textile making machinery, and many others. Rapid advances in technology are expected to drive innovation in this market. As examples, technologies such as 3D printing, artificial intelligence, and big data analytics are being used in manufacturing yielding higher productivity, lower operating costs, and higher margins. IoT applications are also being integrated into these devices to enable services such as remote monitoring, central feedback systems, and other services.
Factory automation implies technologies and automatic control devices to enhance the productivity and quality of products and simultaneously decrease production costs. Also known as industrial automation, it minimizes human intervention in industry and ensures a superior performance compared to humans. Factory automation includes the use of computers, robots, control systems, and information technologies to manage industrial processes.
Robots refer to multifunctional, automatic, and re-programmable industrial machines, which can be embedded in a variety of high-tech devices. They are designed to perform several tasks automatically with speed, intelligence, and accuracy. The essential components of a robot are body or frame, control system, manipulators, and drivetrain. Robots perform tasks across various industries, including healthcare, aerospace, defense, and automotive. The emergence of this technology has facilitated convenience, increased output levels, reduced human errors, enhanced quality, and process automation.

Building Technology
Schaffner delivers Solutions for Energy Efficiency in Building Technology
The quality of power supply in a building is a key factor for its efficient operation. Harmonic disturbances are a common issue in buildings, which can be mitigated, not only to fulfill standards, but also to unburden the interconnected equipment, thereby increasing their lifecycle and improving energy efficiency.
Schaffner’s expertise and broad product portfolio in applications such as HVAC, lighting and elevators enables truly sustainable and energy-efficient buildings.
Markets
We deliver solutions to the following markets:
Heating, Ventilation and Air-Conditioning are responsible for a high proportion of energy consumption in modern buildings. Variable frequency drives are widely used in HVAC applications, where energy efficiency can be substantially improved by mitigating harmonic current present in the energy flow.
Elevators and escalators help to make urban spaces more efficient. Especially in large commercial buildings, elevators and escalators bring people from A to B much faster, easier, and more safely. By applying modern drive technology, elevator motors run as generators during braking and feed energy back into the network or accumulator for later use.
Energy saving lighting systems, such as LEDs together with dimmers and timers, are widely promoted and fitted in modern buildings. They do not only provide a wide range of design and application opportunities. By allowing a dedicated smart light management they also contribute to reduced energy consumption.

Energy Management
Schaffner’s EMC products protect electronical systems from grid distortions, prevent disturbances, and maintain the reliable supply of electrical energy.
Markets
We deliver solutions to the following markets:
Renewable energies are an essential pillar that contribute to making power supply greener. As a result, greenhouse gas emissions – for example – are continuously decreasing in proportion to the increasing share of renewable energies in electricity consumption, and global climate change is being slowed down.
At any moment in time, the consumption of electricity must be perfectly matched with the generation of electricity. This balance is necessary in all electricity grids to maintain a stable and safe supply. Energy storage can stabilize fluctuations in demand and supply by allowing excess electricity to be saved in large quantities over different time periods, from fast storage in seconds to longer storage over days.
Electric vehicle charging stations plug an electric vehicle (EV) to a source of electricity to recharge the EV batteries. Some charging stations have advanced features such as smart metering, cellular capability, and network connectivity. Charging stations are provided, for example, in municipal parking locations by electric utility companies or at retail shopping centers by private companies. Also, the domestic demand for charging possibilities is growing.
The smart and secure use of electrical infrastructures make sense from an ecologic and economic perspective. Even if individual systems and facilities differ among applications, the efficient and demand-based use of energy has become an absolute must. Today, the integration in upcoming Smart Grids as well as the preservation of resources and the environment are as imperative as the technical reliability of appliances, equipment, or systems. Smart meters play a growing role in this environment.
A power supply provides electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. The source power may come from the electric power grid, such as an electrical outlet, energy storage devices such as batteries or fuel cells, generators or alternators, solar power inverters, or other power supply.
An uninterruptible power supply (UPS) takes its power from two or more sources simultaneously. It is usually powered directly from the AC main supply, while simultaneously charging a storage battery. Should there be a dropout or failure of the main supply, the battery instantly takes over so that the load never experiences an interruption. Other UPS schemes may use an internal combustion engine or turbine to supply power during a utility power outage and the amount of battery time is then dependent upon how long it takes the generator to come online. Such arrangements are found, for example, in hospitals, datacenters, call centers, cell sites and telephone central offices.
Oil and natural gas are major industries in the energy market and play an influential role in the global economy as the world’s primary fuel sources. The processes and systems involved in producing and distributing oil and gas are highly complex, capital-intensive, and require state-of-the-art technology. Amongst others they need heavy electrical equipment which suffers from harmonic distortion.
