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

We can also produce fully parameterised drive models 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 decrease the engine’s gear ratio as engine speed increases. This enables the variator to keep carefully the engine within its optimal efficiency while gaining ground speed, or trading rate for hill climbing. Efficiency in this case can be fuel effectiveness, decreasing fuel usage and emissions output, or power efficiency, allowing the engine to produce its optimum power over an array of speeds.

We supply our Digital Variable Speed Drives prepared for installation challenging required options. The drive is already parameterised to this type of electric 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 suitable for all of our geared motor types. Do you want to discover more about our selection of geared motors?
Along with Variable Speed V-Belt Drives, now you can also obtain Electronic Adjustable 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 made from corrosion-resistant materials, maintenance is minimal. This also offers a positive effect on your operating cost balance.
