KSB Motors

KSB launches support program for building technology developed by KSB and SuPremE Motors produced meet the efficiency requirements of class IE4 when operating with the speed control unit PumpDrive (com. IEC(CD) 60034-30 ed. 2). They are now much better than it calls EU law for the year 2017. Now for the technical equipment of the building to make accessible this CO2-friendly technology the Frankenthaler pump producer KSB launches a special funding program. As of October 1, 2013 all speed-adjustable Inlinepumpen are delivered of type Etaline from 0.55 kW up to a performance, including 18.5 kW without extra charge compared with the previous IE2 solution with SuPremE motors. So operators save money immediately after the first commissioning and don’t have to worry about the payback period of the new technology.

Buy traditional high-efficiency motors”is the manufacturer high efficiency in the entire load range through the use of permanent magnets with high power density. From this arise significant disadvantages in the life cycle assessment of these products. Also yet no recycling process is defined so-called rare-earth magnetic materials based on. Magnet free synchronous – reluctance motors, such as the SuPremE motors, represent an economical and environmentally friendly alternative. The CO2 equivalent is a 7.5 kW motor with 16.550 kg significantly below an IE3 asynchronous motor (28.710 kg) and an IE4 permanent magnet motor with 17.560 kg for an operating time of a pump in the heating or cooling system by 15 years. No location detectors are required to operate of the new SuPremE motors. How to get to the same reliability as an asynchronous motor.

The life of the bearings is even slightly raised due to the low heat losses in the rotor. The dimensions are fully compatible to the asynchronous standard motor. The engines produced since March, 2012 in series have proven themselves in numerous industrial applications up to a rated power of 45kW.


Number – an abstract entity used to describe the amount. Sequence. There are different kinds of numbers. Natural numbers 1,2, used for counting objects. Set of natural numbers is denoted. If the natural numbers to add negative numbers and zero, we obtain integers.

Whole numbers in mathematics are studied within the framework of the theory of numbers. Relationships of integers are called rational numbers, or ordinary fractions. The set of all rational numbers is denoted. If by rational numbers add all the endless and non-recurring decimals are called irrational numbers, we get real numbers. Except unit on rational and irrational, real numbers are also classified into algebraic and transcendental. At the same time every transcendental number is irrational, every rational number – algebraic. Real numbers, in turn, can be extended to complex numbers. Complex numbers can be extended to quaternions, but multiplication of quaternions is noncommutative.

In turn, the octave are extensions of quaternions, are already losing the property of associativity. In mathematics, for the sets there is a set amount of power, a similar number of elements in it. The development of this submission for infinite sets led to a further generalization of the concept of number. Now talking about cardinal numbers, which describe the set of any number of elements – finite or infinite.
