Variable Speed Drive

Because the variator keeps the engine turning at constant RPMs over an array of vehicle speeds, turning the throttle grip can make the moped move faster but doesn’t change the sound coming from the engine as much as a conventional two velocity or one acceleration. This confuses some riders and prospects to a mistaken impression of too little power.

We can also produce fully parameterised drive products 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 allows the variator to keep the engine within its optimal efficiency while gaining floor speed, or trading acceleration for hill climbing. Efficiency in this case could be fuel performance, decreasing fuel consumption and emissions result, or power efficiency, permitting the engine to create 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 motor. You only need to make adjustments such as the ramp time, minimum/maximum frequency or limitations to the path of rotation.

Variable Speed V-Belt Drives are ideal for all of our geared engine types. Would you like to find out more about our selection of geared motors?
In addition to 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 manufactured from corrosion-resistant materials, maintenance is minimal. This also has a positive effect on your operating cost balance.
