超低压电动机和驱动架构基于“增大化现实”技术e gaining traction

Interact Analysis has been covering the motor and drive space since its inception. Within the ac motor and drive market, low voltage is commonly understood as being less than 690V. During last year’s edition of our annual low voltage ac motor drive market research, we noticed a common term being mentioned – “Ultra Low Voltage” (ULV).

ULV意味着不到60 v和确定strength of the trend was significant enough to warrant producing a dedicated report on the topic. The first edition of a market report titled Ultra Low Voltage Drives – 2023, which explores the drivers behind the shift towards <60V architectures and where they are gaining the most traction.

Why ultra low voltage?

From a product safety perspective, there are advantages to using <60V systems over their higher voltage counterparts. Within industrial applications, theUL product safety standardmandates products with an input voltage of greater than 60V have additional protective features to mitigate the risk of shock to those encountering the device. As a result, using a <60V system where applicable allows for easier maintenance. Since the system is within a “safe” voltage range, it can be maintained by a less skilled technician without risk of electrocution – something that carries a premium in today’s manufacturing landscape.

The emerging skills gap within the field of manufacturing technicians has been commonly cited as a driver for many trends within the industrial automation sector. As older, more experienced technicians exit the workforce, fewer younger engineers are entering as replacements. Manufacturers are struggling to find labor skilled enough to efficiently perform the necessary maintenance on crucial equipment. For example, predictive maintenance and condition monitoring technology have seen a rapid increase in adoption as a mechanism to reduce this skills gap. The adoption of safer <60V architectures can be viewed through a similar lens.

Additionally, ULV is lower cost and may not require use of full-suit personal protective equipment (PPE) when control cabinets are designed correctly, separating low from higher voltages. Installation may be less expensive in labor cost compared to installing 120 V and above.

Increasing prevalence of battery driven processes

The second major driver towards <60V architectures stems from the increasing prevalence of battery driven applications within industry. Automated guided vehicles (AGVs) and autonomous mobile robots (AMRs), most notably, have seen sales increase significantly in recent years and the market for these vehicles is anticipated to continue to grow at a steep rate. The majority of these vehicles operate with a 24 or 48V battery. Consequently, the motors and drives used fall within the ultra-low voltage threshold.

Over the next five years, ultra-low voltage drives sold to the AGV and AMRs sector are forecast to see a CAGR of 71%, making it the fastest growing sector covered within our report. By 2027, we expect the sale of ultra-low voltage drives to AGV/AMR applications to comprise approximately 55% of total market revenues.

Growth in automation of auxiliary systems

The next significant driver of growth for the ultra-low voltage motor and drives market is a bit more nuanced. Within machinery, particularly machinery with an abundance of small actuation points, there is an increased level of automation being employed in historically manual processes. A prominent example can be found within packaging machinery. As packaging machines are designed to accommodate multiple products, packaging materials, etc. the machine has to become more flexible.

Historically, materials or systems had to be adjusted manually, whereas machine builders are now pushing more automation into these auxiliary systems to enable more efficient processes. Ultra-low voltage brushless dc and stepper motors are often selected to carry out these automated processes due to their high level of control, ease of maintenance and low cost. As a result, ultra-low voltage drive usage is increasing within these types of systems.

As market analysts, we often see trends in our areas of coverage influencing other sectors. The ultra-low voltage trend was brought up unprompted in several interviews with suppliers operating in both markets. This often indicates significant growth for the trend in question as it has begun to influence sales of related products.

We produced research into this market under the hypothesis that we would find significant growth. After speaking with suppliers of the products and finalizing the research, we can consider our hypothesis confirmed.
