New motor range meets WIMES specification
03 May 2015
Matching motors to specific water industry standards and specifications has been made easier with ABB’s new range of WIMES compliant electric motors. Also new from ABB are smartphone apps that can be used to tune and commission new variable speed drive installations.
The Water Industry Mechanical and Electrical Specification for low voltage AC motors (WIMES 3.03 issue 6), created by The Pump Centre working closely with 17 water companies across the UK, defines the mechanical and electrical requirements for equipment used in the UK water industry.
ABB’s new motor range, designed specifically to meet the WIMES specification, offers end-users and original equipment manufacturers (OEMs) a wide choice of motor designations and options for use in any motor-driven application in the water sector.
ABB’s WIMES compliant motor range is available in cast iron frame sizes from 80 to 450 and aluminium frame sizes from 80 to 180, rated from 0.75 to 1,000kW. The totally-enclosed fan-cooled motors come in IE3 premium efficiency and IE4 super premium efficiency variants.
A new range of medium voltage motors for the water industry is also available from 200 to 2,000kW power range, in frame size from 355 to 560.
Greater protection against external conditions found in the water and wastewater industry are built into the WIMES compliant motor. These range from a stainless steel nameplate to a frame made of high grade robust cast iron with a surface treatment to C3M corrosion tolerance according to ISO 12944-2: 2007. V-ring seals and labyrinth seals are used to protect the shaft and internal components.
PTC thermistors are contained within the windings of the motor to protect against overheating, with cooling fans optimised for low noise levels protected by a steel fan cover to guard against impact damage. Larger motors are fitted with Pt100 temperature sensors in the windings to give additional preventive protection, as stipulated by the WIMES specification.
The winding insulation is suitable for frequency inverter duty applications (415V), with insulated bearings where required, making ABB WIMES compliant motors compatible for use on variable-speed controlled applications such as pumps, fans and compressors.
Heating elements are fitted within the windings which can help protect the motor from the effects of condensation.
Smartphone apps for drives
The new ABB smartphone applications for its variable-speed drives, help save time, ease troubleshooting and improve drive performance via convenient technology of the Internet of Things, Services and People (IoTSP).
ABB’s Drivetune allows service engineers and installers to easily connect to a drive via wireless Bluetooth connection. Then, using a user-friendly smartphone interface, the installer can more quickly and efficiently commission and tune a drive’s performance, allowing quick resolution of any initial issues without being forced to take the drive offline.
Drivebase, an ABB App that’s been improved since its introduction in 2014, allows plant personnel to scan a dynamic QR code generated by a drive on its control panel. The code provides information for registering the drive and about remedies for potential problems without resorting to maintenance manuals, while simultaneously drawing on ABB’s vast drive knowledge base via the cloud should further assistance be needed.
Drivetune will speed and ease the work of engineers, installers and system integrators commissioning drives at an industrial site. It will also be capable of connecting wirelessly to ABB drives, meaning engineers won’t need to enter hazardous or difficult-to-reach work areas to access information necessary to help them commission and tune a drive.
Drivebase, meanwhile, helps plant operators track and maintain their drives throughout their life cycles and opens new opportunities for them to tap into ABB expertise. From the moment the drive has been installed and through its lifecycle, Drivebase can maintain a historical record that will help ABB’s service team make proactive recommendations to ensure reliability and reduce downtime.
ABB says it will update the apps and expand the range of drives that can be connected to them, to offer new functionality, service and convenience.
The Drivebase App is widely available on all the most common smartphone platforms via Google play, Apple App Store and Windows Store. The new Drivetune App will be available later this year.
