Since the variator keeps the engine turning at constant RPMs over an array of automobile speeds, turning the throttle grip can make the moped move faster but doesn’t change the sound from the engine as much as a conventional two rate or one acceleration. This confuses some riders and leads to a mistaken impression of a lack of power.

We can also produce fully parameterised drive units on request. For this, we load a data record that you provide into the frequency inverter after completion of the standard tests.
Variomatic transmissions use centrifigual weights to diminish the engine’s gear ratio as engine speed increases. This enables the variator to keep the engine within its ideal efficiency while gaining surface speed, or trading velocity for hill climbing. Variable Speed Drive performance in this case can be fuel performance, decreasing fuel intake and emissions output, or power efficiency, allowing the engine to produce its maximum power over a wide variety of speeds.

We supply our Digital Variable Speed Drives prepared for installation with all of the required options. The drive is already parameterised to the particular type of motor. You only need to make adjustments like the ramp time, minimum/maximum frequency or restrictions to the direction of rotation.

Variable Speed V-Belt Drives are ideal for our geared motor types. Do you want to find out more about our selection 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 course 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 operating cost balance.
