FAQs + basics

What are voltage monitoring relays and how are they used?

November 13, 2020 By Danielle Collins Leave a Comment

voltage monitoring relays

Relays are used in motor-driven applications to measure and monitor operating parameters such as temperature, current, or voltage, preventing damage to the motor and connected equipment in the case of a fault or abnormal operating condition. Voltage monitoring relays can detect not only under-voltages and over-voltages, but also voltage-related issues such as phase imbalances, phase […]

Contactless energy transfer, cable-free communication open up new possibilities for machine builders

November 10, 2020 By Miles Budimir Leave a Comment

EtherCAT

One of the more promising recent developments in connection technology is contactless energy and data transfer and its use in the industrial world. Such technology can replace wiring and cables and cable carriers, lowering costs and streamlining designs. For instance, robotic systems are sometimes limited by constraints in automation and drive technology. However, consider the […]

What is a zero pressure accumulation conveyor?

November 6, 2020 By Danielle Collins Leave a Comment

zero pressure accumulation conveyor

A common function of a conveyer system is to accumulate products — in other words, to stop them from moving along the conveyor to create a buffer, establish a queue, or smooth out differences in material movement between upstream and downstream operations. But traditional accumulation methods allow products to bump into each other and stack up […]

Micro motors give robotic hand a boost

November 6, 2020 By Miles Budimir Leave a Comment

robotic glove

Among the changes to small motor design over the years has been the use of powerful rare-earth magnets to increase power density, making for smaller and more powerful motors. These motors are finding their way into medical devices, robotics, as well as the intersection of these two. Case in point; a robotic glove. Ironhand from […]

Sensors aid packaging machine flexibility

November 5, 2020 By Miles Budimir Leave a Comment

sensor

Sensors have always been the unseen elements that make complex machines perform at their optimal level. This is true for all kinds of machines, including the latest generation of packaging machines. Companies that need to invest in packaging machines value flexibility where a single machine can handle a wide range of package sizes and formats. […]

What are geared cam limit switches?

October 28, 2020 By Danielle Collins Leave a Comment

geared cam limit switches

Electromechanical switches are often placed at the ends of linear axes to indicate the limits of travel. But for applications with rotary — rather than linear — motion, geared cam limit switches can perform a similar function by tracking rotations of the motor shaft and triggering switches to stop movement when the specified number of […]

What are thermal overload relays and what motion components do they protect?

October 21, 2020 By Danielle Collins Leave a Comment

Heat is a major factor in the performance and life of a motor, and one of the primary sources of motor heating is current running through the motor windings. Since heating is an unavoidable condition of motor operation, it’s important to protect the motor from overheating, or thermal overload. In a previous post, we described […]

What are HMI-PLC combination units and where do they make sense?

October 16, 2020 By Miles Budimir Leave a Comment

HMI PLC

PLCs have long been an industry standard in machine control. They range in size and function from the simplest of controllers with the most basic ladder logic instruction set to multi-function complex units that can provide multiple control modes from basic control functions to process control and even motion control functions. (Programmable automation controllers, or […]

What’s the difference between dynamic braking and regenerative braking?

October 15, 2020 By Danielle Collins Leave a Comment

regenerative braking

When a motor’s rotor speed is greater than its synchronous, or designated, speed, it can act as a generator, creating electrical energy from mechanical energy. This electrical energy needs somewhere to go, and there are two ways to deal with it — dissipate it as heat, or reuse it. Dynamic braking takes the energy generated […]

What are busbars and how are they used in motion control applications?

October 14, 2020 By Danielle Collins Leave a Comment

busbars

Busbars are components that facilitate the distribution of power to electrical equipment, supplementing or replacing traditional wiring in applications such as commercial facilities, data centers, and industrial plants. At their most basic, busbars are relatively simple bars, strips, or rods made of copper, brass, or aluminum, but in many cases, they’re constructed in specific shapes […]
