The Impact of Tariffs on Industrial Automation


Industrial automation has become a cornerstone of modern manufacturing, driving efficiency, productivity, and competitiveness. However, the increasing use of tariffs—taxes imposed on imported goods—has introduced new complexities for businesses relying on automation technologies. While tariffs aim to protect domestic industries, they can also disrupt supply chains, increase costs, and slow innovation in industrial automation. This article explores the effects they have on the automation sector.

What Are Tariffs?

There exists the misconception that tariffs are a tax on exporters. However, that simply isn’t true. A tariff is an import tax that gets put upon the importing company not the exporting company. Typically the importing party pays the tariff then in turn passes the cost of the onto their customers by marking up the price of the goods imported in.




How Tariffs Affect Industrial Automation

1. Increased Costs for Automation Components

Many industrial automation systems rely on imported components, such as robotic arms, sensors, controllers, and motors. When tariffs are imposed on these goods, manufacturers face higher procurement costs. For example, U.S. tariffs on Chinese-made automation parts have forced companies to either absorb the extra expenses or pass them on to customers, leading to higher prices for automated systems.

2. Supply Chain Disruptions

Tariffs can disrupt global supply chains by making certain suppliers less competitive. Companies that depend on just-in-time manufacturing may struggle with delays and shortages if they must switch suppliers due to tariff-related cost increases. This can slow down automation adoption as businesses face uncertainty in sourcing critical components.

3. Slowdown in Automation Adoption

Small and medium-sized enterprises (SMEs) that are considering automation may delay investments due to higher costs from tariffs. This could slow overall productivity growth in manufacturing, as automation is a key driver of efficiency.

4. Encouragement of Domestic Production

On the positive side, tariffs may incentivize companies to produce automation components locally. Countries imposing tariffs often aim to boost domestic manufacturing, which could lead to increased investment in homegrown automation technologies. However, building a competitive local supply chain takes time and may not immediately offset the negative effects of tariffs.

5. Trade Wars and Long-Term Uncertainty

Ongoing trade tensions, such as those between the U.S. and China, create uncertainty for automation suppliers and manufacturers. Companies may hesitate to make long-term investments in automation if trade policies remain unpredictable.

Are There Advantages to Tariffs?

While tariffs are generally looked down upon for their disruption to the flow in the global economy. When used responsibly and with proper domestic infrastructure in place, tariffs do have certain advantages.

Reshoring of Manufacturing

Companies may bring production back to domestic markets, increasing demand for localized automation solutions.

Innovation in Alternative Technologies

Higher costs for imported components could accelerate the development of new automation technologies that rely less on tariff-affected parts.

Strategic Sourcing Diversification

Businesses may seek suppliers in countries not subject to tariffs, leading to a more resilient supply chain.

Conclusion

Tariffs can present obstacles and potential opportunities for industrial automation. While they raise costs and disrupt supply chains, they may also encourage domestic production and innovation. Companies in the automation sector must adapt by diversifying suppliers, investing in local manufacturing, and exploring new technologies to mitigate risks. Policymakers should also consider their long-term impacts on industrial competitiveness, ensuring that trade policies support—rather than hinder—technological advancement.

As automation continues to transform manufacturing, navigating trade-related challenges will be crucial for sustaining growth and maintaining a competitive edge in the global market.

Three-Phase Power

Three-phase power remains a widely used method for generating, transmitting, and distributing electricity. It is more efficient than single-phase and is the backbone of industrial and commercial electrical systems. This article explores the history of three-phase and its most common applications today.

How Three-Phase Power Works

Three-phase power consists of three alternating currents (phases) spaced 120 degrees apart. This
arrangement ensures a constant energy delivery, unlike single-phase systems, which have energy
fluctuations. Key advantages include:

  • Higher Efficiency
    • Requires less conductor material compared to single-phase for the same power output.
  • Smoother Power Delivery
    • Ideal for running large motors without interruptions.
  • Flexibility
    • Can power both industrial equipment and residential areas by splitting phases.

History

Before three-phase power, electrical systems primarily used direct current (DC) or single-phase alternating current (AC). Thomas Edison promoted DC power, while Nikola Tesla and George Westinghouse advocated for AC due to its ability to transmit electricity over long distances. In 1887 Tesla developed the first AC induction motor. This motor was capable of both two and three phase. Tesla’s work demonstrated that three-phase systems were more efficient for energy transmission and motor operation.

In 1891, the first long-distance three-phase power transmission became demonstrated at the International Electrotechnical Exhibition in Frankfurt, Germany. Engineers Dolivo-Dobrovolsky, Mikhail Osipovich, and Charles Eugene Lancelot Brown successfully transmitted 175 kW of power over 175 km with minimal losses, proving the superiority of three-phase AC. The success of this demonstration paved the way for modern three-phase and by the early 20th century, three-phase power became the standard for industrial and commercial power distribution. This was primarily due to its efficiency, reliability, and ability to power large motors.

The Tesla Polyphase was the first example of a three phase motor.

Most Common Uses for Three-Phase Power

Since its inception in the 1800’s, three-phase power has seen itself used in a wide variety of industries and applications. It sees the most use in the industrial sector. Factories use three-phase to run heavy equipment such as pumps and conveyor systems without voltage drop. You can read more information about three-phase and AC Motors in the industrial sector here.

In the commercial sector, like shopping centers, hospitals, and office, three-phase power gets used in HVAC systems to keep the buildings habitable all year long. The renewable energy sector sees three-phase being generated and fed back into the energy grid.

Three-phase power also finds a more direct to consumer use as well. It gets used to power data centers all over the world. The computational power of these server require stable high capacity voltage which three-phase excels in providing. As of late, three-phase has found their use in the electric vehicle industry being used at charging stations for people to charge their vehicles.

Conclusion

Three-phase power revolutionized electrical engineering with its efficiency and reliability. From its origins in Tesla’s innovations to its widespread use in industry and infrastructure, three-phase systems remain the standard for high-energy applications. As technology advances, three-phase will continue to play a crucial role in modern energy systems.
