Since the variator keeps the engine turning at continuous RPMs over an array of vehicle speeds, turning the Variable Speed Drive throttle grip will make the moped move faster but doesn’t change the sound from the engine just as much as a conventional two acceleration or one quickness. This confuses some riders and leads to a mistaken impression of a lack of power.

We can also create fully parameterised drive systems on request. For this, we load a data record which you provide into the frequency inverter after completion of the typical tests.
Variomatic transmissions use centrifigual weights to diminish the engine’s gear ratio as engine speed increases. This allows the variator to keep the engine within its optimum efficiency while gaining surface speed, or trading rate for hill climbing. Effectiveness in this case can be fuel performance, decreasing fuel intake and emissions result, or power performance, enabling the engine to create its optimum power over an array of speeds.

We supply our Electronic Variable Speed Drives ready for installation challenging required options. The drive has already been parameterised to this type of motor. You only need to make adjustments such as the ramp time, minimum/maximum frequency or restrictions to the path of rotation.

Variable Speed V-Belt Drives are ideal for all of our geared motor types. Would you like to discover more about our range of geared motors?
As well as Variable Speed V-Belt Drives, you can now also obtain Electronic Variable Speed Drives, which consist of a frequency inverter from the SK200E and SK180E series, an IE2 or IE3 efficiency class asynchronous motor, and a NORD gear unit.

As the adjustment discs for the VBelts are produced from corrosion-resistant materials, maintenance is minimal. This also has a positive influence on your working cost balance.
