About LV Motors

Electric motors are electromechanical energy converters; their function is based on the effect of magnetic forces between electric currents and magnetic fields, which are usually also electrically generated. This principle explains why electric motors have a relatively high efficiency. Typical efficiencies for an 11 kW standard motor are around 91 per cent, and 95 per cent for a 110 kW motor. In accordance with growth laws, the efficiencies of larger motors are higher than those of smaller ones.

The art of motor design and dimensioning lies in finding an optimum balance between losses and the required operating properties. Depending on the type of electrical machine and its underlying design principle, each of these factors can be influenced to a greater or lesser extent by dimensioning. However, there is hardly any scope left for further technical optimization of efficiencies in today’s motors.
