Variable Speed Drive

Because the variator keeps the engine turning at constant RPMs over a wide variety of vehicle 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 speed or one acceleration. This confuses some riders and prospects to a mistaken impression of too little power.

We can also generate fully parameterised drive units on request. For this, we load a data record that you provide in to the frequency inverter after completion of the standard tests.
Variomatic transmissions use centrifigual weights to decrease 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. Performance in this case can be fuel performance, decreasing fuel consumption and emissions result, or power performance, enabling the engine to produce its optimum power over an array of speeds.

We supply our Digital Variable Speed Drives ready 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/optimum frequency or limitations to the direction of rotation.

Variable Speed V-Belt Drives are suitable for our geared engine types. Do you want to find out more about our selection of geared motors?
In addition to Variable Speed V-Belt Drives, now you can 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 made from corrosion-resistant materials, maintenance is minimal. This also has a positive influence on your operating cost balance.
