Applying industrial automation servos places additional constraints on the rules for power transmission design. Engineers must consider various options and risks when designing speed reducers, couplings, shaft configurations and other critical mechanical components. Mechanical load problems typically caused by backlash and/or compliance problems can be avoided with careful analysis.
Optical coupling fluids and gels serve as a “bridge” for light signals by carrying light between different media such as transparent plastic or glass light pipes or lenses. These materials, also known as Index Matching fluids and gels, are used to optimize light transmission (by matching the refractive index of the mating materials) while allowing pliable mechanical connections between rigid parts.
Industrial applications such as the factory floor are typically electrically noisy environments. Electrical noise, either radiated or conducted as electromagnetic interference (EMI), can seriously disrupt the proper operation of other equipment. Insulation protects a cable mechanically from scraps and abrasion and environmentally from moisture and spills, but insulation is transparent to electromagnetic energy and offers no protection. Shielding is needed to combat the effects of EMI.
A cable that is intended to be deployed in flexing applications is, by its very nature, a flexible cable – or is it? Actually this is not necessarily true and although many may just see this as a simple case of semantics, the truth is that many flexible cables are not actually suited to environments that subject them to constant bending and flexing cycles. In today's competitive world of highly complex electronics, cable failure is never an option.
Cable failure is not an option. There is no acceptable level of downtime and no one can afford to replace expensive machinery years before its predicted lifespan - not when profit margins are razor thin and competition is breathing down your neck from all four corners of the world. Expanding temperature ranges, shielding options, mechanical durability and chemical resistance, among other performance characteristics designed to meet the demands of extremely harsh environments in increasingly complex applications is key when specifying cables.
Variable-frequency drives (VFD) allow sophisticated AC motor control by allowing their speed and torque to be precisely adjusted. Control is achieved by varying the frequency to the motor. It does not, however, transmit a pure sine-wave frequency. Rather it sends a series of pulses, whose width varies, to the motor. This technique—pulse-width modulation—supplies the drive with the same power profile as a sine-wave frequency. While PWM provides an excellent way to control a motor’s speed and torque, it creates several phenomena that can affect the power, create noise, reduce the life of the cable, and disrupt operation of the drive system
A new alternative wire insulation to PVC offers better performance and significantly less environmental impact. Although PVC insulation is a mainstay due to its mechanical and electrical properties, as well as its low cost, it presents environmental issues due to its halogen content. Halogens are elements such as fluorine, chlorine, bromine and iodine that are highly reactive and can be harmful to people and animals. PVC contains approximately 29 percent chlorine by weight.
Many process plants currently use steam or hot water to heat jacketed devices such as tanks, kettles, dryers, reactors, glass lined vessels, or similar adaptations such as coiled tubing placed inside or outside tanks or vessels. In this article, we will take an in-depth look at the advantages and disadvantages of steam and hot water for jacketed heating, and compare indirect and direct steam injection systems for making hot water.
Shim tooling costs are one of the quickest ways to drive a prototype or short-run production project over budget. SPIROL has several manufacturing methods that eliminate or greatly reduce your tooling expenditure, whether your project is for prototype, short-run or long-term requirements. Below are some production technologies to help you determine which method is best for you.
Mechanical Drive connections using Polygon systems can transmit up to double the torque transmitted by other conventional drives within the same shaft diameter.
The demand for extremely low-power technologies was born from necessity; starting with the fabrication process and moving all the way to application areas. Particularly, energy sensitive applications are now driving demand for unprecedented hours of service from a single battery that is measured in years rather than in days or months. Meeting this demand requires integrated devices that are not only developed in synergy with the characteristics of battery power, but also with an understanding of how the application will operate in order to achieve 10, 15 or even 20 years of operation without replacing the primary cell. This white paper describes the benefits of low-power design technology and applicable scenarios.
Permanent magnet direct current (DC) motors convert electrical energy into mechanical energy through the interaction of two magnetic fields. Here are some key points to consider when specifying DC motors.
The 8-bit microcontroller has been around for close to 40 years. In this age of rapidly advancing technology, when electronic devices seem to become obsolete not long after they get to market, that boggles the mind. To what can we attribute such longevity? There are a variety of reasons as outlined in this paper.
Photo etching, also called chemical milling, offers many advantages for manufacturing thin metal or polymer film medical parts, including improved accuracy, low-cost tooling, inexpensive prototyping, burr-free parts, and faster production times.
