Selecting Motors And Drives For Explosive Atmospheres

When selecting variable speed drives and motors for potentially explosive atmospheres, the manufacturer’s instructions and recommendations must be followed, otherwise explosion protection measures will be compromised. ABB’s Luciano Santos and Andrew Bould share some advice. Throughout the food and beverage sector, variable speed drives (VSDs) and electric motors are renowned for contributing to productivity improvement and energy efficiency. However, their use needs to be very carefully considered in applications within potentially explosive atmospheres – also…

Choosing the right type of electric motor can improve energy savings

Not all low voltage motors are the same. With a wide range of different motor technologies on the market, each with their own strengths and weaknesses, choosing the most appropriate motor type for an application can pay strong dividends over the course of the motor’s lifetime. The four most widely used types of motor are: • Induction motors • Permanent magnet motors • Synchronous reluctance motors (SynRM) • Electronically commutated motors (ECM) Each technology achieves…

Building efficiency safety and comfort with drives and motors

Regardless of the season or external conditions, variable speed drives help make HVAC applications efficient, safe and informative while providing high levels of comfort, control and safety. Here ABB’s Carl Turbitt takes a tour around a typical in plant and highlights the opportunities. 1 Cooling tower A cooling tower extracts waste heat into the atmosphere. Using a variable speed drive, instead of conventional direct-on-line or Star-Delta control, means the tower’s fan and pump speed can…

How to protect your motors from high pressure washdowns

The use of high pressure washdowns to clean equipment is standard practice in many food and beverage facilities. However, when it comes to electric motors, this can present challenges. ABB’s Luciano Santos looks at what is needed to maintain hygiene without compromising on productivity or reliability. Food production and hygiene are inseparable and handling equipment, preparation vessels and surfaces need to be kept scrupulously clean. This is typically done using chemicals and high pressure washdown,…

SynRM Improves Energy Use Reduces Maintenance And Lowers Noise In Pipe Extruder

Constant torque application benefits from SynRM technology Up to 15 percent lower energy use, a significant reduction in motor maintenance costs and a drop in audible noise are achieved with the installation of an ABB synchronous reluctance motor and drive (SynRM) package on a twin extruder application. Radius Systems’ plant in Derbyshire, UK, houses 14 extrusion lines, each of which produces polyethylene pipes from 16 mm to 1200 mm, together with an injection-moulding facility making…

The Importance Of High Motor Efficiency

Rob Wood, UK Sales Manager – LV Motors, ABB Limited, says: The world is facing a serious energy challenge. Demand for electricity will grow faster than for any other form of final energy. Pressures to reduce energy consumption and lower carbon dioxide emissions come from everywhere. One of the simplest ways to address this challenge is to seize the opportunities for energy reduction that come from using energy more efficiently. Over 40 percent of generated…

DC – AC Motor Conversion

Thirty years ago, DC motors were the workhorse of industry when variable speed was required. These were found in many applications including mine winders, extrusion applications and the steel industry. However, they needed a maintenance schedule including regular brush changes and carbon removal from the windings. Every so often, a major overhaul was required in a workshop to skim the commutators. The DC motors also had inefficiencies with the brushgear and complicated winding arrangements. DC…

Why do pump motors fail?

Dave Hawley, General Manager – Motors, ABB Limited, writes: There is a lot of debate about whether it is better to repair or replace a failed pump motor. A far better option is to ensure it doesn’t fail in the first place. In theory, a motor could run for as long as 50 years, substantially beyond the retirement date of the connected machine. This can be achieved with regular preventive maintenance targeting the most common…

Why the Reluctance?

When it comes to efficiency, if you were to put a synchronous reluctance motor (SynRM) head-to-head against an equivalent induction or permanent magnet motor the former will easily come out on top. Yet, despite this and many other advantages, SynRM remains far from ubiquitous in industry. Dave Hawley, General Manager for Motors & Generators, ABB, explores five myths surrounding the technology. MYTH: SynRMs are only suitable for certain applications SynRMs are compatible with almost any…

Electric Motors Get Smart

Low voltage electric motors power a wide variety of applications, in almost every aspect of industrial life. From Heating and Ventilation systems, pumps, fans, grinders, compressors, conveyors, mixers, the application list is almost endless. We know the importance of maintaining these workhorses, but what if you knew the condition of each motor on your site, handy? What if the key metrics of your electric motors were communicated directly to your phone or device on a…
