New Simotics standard motors with highest efficiency class

Siemens Industry Automation & Drive Technologiesvisit website

 

Siemens UK and Ireland is launching IE4, its new Simotics low-voltage motors based on the highest efficiency class technology currently available, to help UK plants meet stringent energy saving standards.

The IE4 motors are from the Simotics GP and Simotics SD series and offer up to 14 per cent higher efficiency than the IE1 portfolio, enabling users to achieve significant energy savings, as well as reduce associated operation and maintenance costs.

Designed to DIN EN 50347 Standard, the IE4 can easily replace existing IE1, IE2 or IE3 motors. For example, Simotics low voltage IE4 motors are suitable for use in pump, fan and compressor applications, as well as many more industrial applications.

Based on the 1LE1 platform, the highly efficient IE4 motors are available in aluminium housing (Simotics General Purpose), with a range from 2.2 to 18kW, as well as cast-iron housing (Simotics Severe Duty) offering a range of 2.2 to 200kW, with two and four-pole versions available.

The motors can be operated directly on-line or converter fed, which also results in greater flexibility, particularly in retrofit projects. Since the standard output and shaft height assignment have been retained for the IE4 version, it is easy to replace the motors.

Muhammad Haroon at Siemens UK & Ireland, comments: “In view of the increasingly stringent energy saving standards, not only within the EU but globally, the launch of our IE4 series enables industrial plants to equip themselves for the future, while making substantial savings on energy. The Siemens IE4 range is great for retrofit applications as the shaft height stays the same and offers greater flexibility as it can be used for line operation (DOL) as well as with a variable speed drive. It represents the development of our SIMOTICS 1LE platform and everything about the series, from the housing design to output, has all been designed to deliver the highest levels of efficiency and ease of application.”

Simotics motors are suitable for use in all industries, but particularly in the chemicals, oil and gas, water/wastewater, mining and heating, ventilation and air conditioning sectors. The motors’ asynchronous design constitutes a reliable technology for pump, fan and compressor applications.

While general-purpose motors are appropriate for use in day-to-day applications in standard environmental conditions, the Severe Duty motors with their rugged cast-iron housing fulfil the more demanding requirements found in the paper and printing industry, as well as the chemicals and petrochemicals industry.
