IEC low voltage motors for water and wastewater

ABB offers a wide range of low voltage IEC motors, from classical induction motors that provide high efficiency levels to synchronous technology that exceeds conventional efficiency requirements. Meeting water specifications means that public and private utilities and OEM's can confidently specify a motor for any pump, compressor or fan application that is used in the water and waste water sector.

ABB motors operate in a wide range of water and waste processes and applications including:

  • pumping stations
  • inflow pumps
  • irrigation systems
  • water and wastewater networks
  • mixers, closing pumps
  • transfer pumps
  • water and wastewater treatment
  • sludge pumps
  • desalination processes
  • compressors
  • fans

The motors have many features that provide greater protection against the environmental conditions found in water and wastewater applications.

  • Protection against the external conditions found in the industry
  • Bearings locked at D-end to avoid axial play
  • Bearings can be either greased for life or re-greasable, fitted with grease relief systems
  • Fan and motor fits optimized for low noise levels
  • Oversized terminal box eases installation
  • IP55 protection as standard, IP56 as option
  • Surface treatment according to corrosion class C3M, C4 and C5 as option
  • IE3, IE4 and IE5 to support emission reduction
  • Designed for frequency converter operation

Key features

  • Reduced losses mean that motors run cooler with extended re-greasing intervals, and have a longer bearing lifetime and enhanced insulation life.
  • Seals are used to protect the bearings and internal components from ingress of harmful amounts of water and solids.
  • Frames aluminum or high grade robust cast iron with surface treatment according to C3M
  • Bearings locked at D-end for low axial play.
  • Bearing either permanently greased or re-greasable, fitted with a grease relief system
  • Bearings grease -30° to 120°C
  • Oversized terminal box fitted as standard for ease of installation
  • Fan and motor fins optimized for low noise level
  • Motor vibration level according to grade A (IEC 60034-14)

Motor range:

  • Power range: 0.09 to 1000 kW
  • Frame sizes: 63 to 450, aluminum and cast iron frame
  • Efficiency classes: IE2, IE3, IE4

Key features

  • Space and weight saving by compact construction and elimination of internal or external fan
  • Heat loss is expelled through the cooling circuit in an economically, and does not affect the immediate surroundings
  • Insensitive to pollution and temperature fluctuations in the ambient air

Motor range:

  • Up to 2 MW
  • Frame sizes: 280 to 500

Synchronous motors are typically preferred when high reliability, super premium efficiency, precise motor control even at low speeds, and compact overall equipment size is required. 

Synchronous reluctance motors

The advantages of permanent magnet technology combined with the simplicity and service-friendliness of an induction platform. Each motor-drive package combines proven stator technology, an innovative magnet-free rotor design, a best-in-class industrial drive and advanced software to offer a complete, optimized solution. 

Permanent magnet motors 

The permanent magnet motor range extends the effective nominal speed range of the rugged industry workhorses down to 100 – 850 r/min. The motors can simplify drive systems by effectively eliminating the need of speed reduction devices. They are designed exclusively for a frequency converter supply, where they provide high speed accuracy even without speed sensors because they are synchronous motors without rotor slip.
