More stopping power for servo motors -- using less space

Miki Pulley's BXR-LE spring-applied Electro-Magnetic brake series safely holds a static position, without the need for external power. When the stator is energized, the brake is disengaged allowing free rotation. When no current is applied, compression springs halt the brake rotor, thereby stopping the input shaft rotation. This is an ideal feature to prevent rotation during power failure events. There are six total size configurations in the BXR-LE series to choose from. Of particular importance: These brakes have a slim design and high holding torque in a very compact package. Great for robotics.

Variable frequency drives benefit constant speed applications

Using a variable frequency drive (VFD) can be beneficial in many constant speed applications driven by electric motors, such as those that require controlled starting and have been historically served by a reduced-voltage soft-starter (RVSS). While an RVSS and a VFD can both provide a controlled start, let's examine the benefits of each technology and when it makes sense to use one over the other.

New inductive-technology position sensors

Novotechnik's TF1 Series touchless linear position sensors overcome issues with legacy magnetostrictive technology. They are unaffected by strong magnetic fields and metal flakes or filings present in a user's environment. The TF1 Series consists of an inductively coupled position marker attached to a moving rod/piece of the user's application that requires a position measurement and the sensor with operational and programming status LEDs. While operating, LEDs indicate whether the sensor is operating and the marker within measuring range or out of range, as well as indicating results of internal diagnostics for valid output from the sensor. Can also measure speed and temperature.

U.S. robot density now more than double that of China, but Korea and Singapore are way out in front

Robot sales in the United States hit a new peak of almost 38,000 units, setting a record for the eighth year in a row (2010-2018). Today, robot density in the U.S. manufacturing industry is now more than double that of China and ranks seventh worldwide. These results were published recently by the International Federation of Robotics (IFR) headquartered in Germany.

Robot density in the U.S. manufacturing industry reached 200 robots per 10,000 employees vs. 97 in China (2017). The trend to automate production in both domestic and global markets is the main driving force of robot installations in the United States. The general industry sector, particularly the food and beverage industry (+64 percent) and the plastic and chemical products industry (+30 percent), had the highest growth.

Automotive industry
In terms of market share, the automotive sector is the most important customer for robots. The U.S. car market is the second-largest car market in the world after China. Within the U.S. automotive sector, part suppliers account for two-thirds of installations: Sales went up by 9 percent (2017-2018). However, car manufacturers (OEM) invested less in automation -- installations went down by 26 percent. The average annual growth rate of robot sales to the U.S. automotive industry between 2013 and 2018 was 7 percent.

Robot density in the automotive industry increased by 52 percent between 2012 and 2017, from 790 to 1,200 industrial robots in operation per 10,000 employees (robot density China 2017: 539 units). According to the Bureau of Labor Statistics USA, employment in the automotive industry increased by 22 percent from 824,400 to 1,005,000 jobs (2013-2018).

Electrical/electronics industry
The electrical/electronics industry was the second most important customer in 2018 with a market share of 18 percent of the total supply. From 2013 to 2018, robot installations increased by 15 percent on average per year.

The number of installations rose by some 2 percent to almost 6,700 units in 2018. In terms of new developments, several production sites for lithium-ion batteries as well as for chips and sensors have been created in recent years, and more will be established in years to come.

North America: USA, Canada, Mexico
"The North American countries (United States, Canada, and Mexico) represent the second-largest operational stock of industrial robots in the world after China," says Junji Tsuda, president of the International Federation of Robotics. "Whilst numerous important robot system integrators come from North America, most big robot manufacturers are based in Japan, Korea, and Europe.

You will be able to see the latest innovations in robotics, vision, motion control, and automation technologies from around the world at North America's No. 1 robot and automation event, Automate 2019, in Chicago from April 8-11.
