The problem with such an arrangement is that a portion of the motor's weight is unsprung , increasing unwanted forces on the track. In the latter part of the 20th century, vehicles with electrical transmission systems powered from internal combustion engines , batteries or fuel cells began to be developed—one advantage of using electric machines is that specific types can regenerate energy i. To reduce these losses, electric locomotives and trains before the advent of power electronics were normally equipped for series-parallel control as well. Because overhead line pylons possess a smaller cross section than traction current masts, these cross beams have to be quite narrow, so the arrangement of four conductor cables in one level, which is standard at traction current lines, cannot be used. In such cases, the traction current lines must use insulators which can cope with the maximum peak-to-peak voltage which can occur between the lines. Then in collaboration with you, we apply our engineering expertise focusing on what is core to your business. We offer a novel approach which gives you the shortest development lead times for customized IGBT inverters on the market. Elevators, escalators, moving walks, modernizations, hand dryers.
