Since the variator keeps the engine turning at constant RPMs over a wide selection of vehicle speeds, turning the throttle grip will make the moped maneuver faster but doesn’t change the sound coming from the engine just as much as a conventional two speed or one speed. This confuses some riders and leads to a mistaken impression of too little power.

We can also create fully parameterised drive products on request. Because of this, we load a data record that you provide into the rate of recurrence inverter after completion of the typical tests.
Variomatic transmissions use centrifigual weights to decrease the engine’s gear ratio as engine speed increases. This allows the variator to keep the engine within its optimal efficiency while gaining ground speed, or trading rate for hill climbing. Efficiency in this case could be fuel effectiveness, decreasing fuel usage and emissions result, or power efficiency, enabling the engine to create its maximum power over a wide range of speeds.

We supply our Digital Variable Speed Drives prepared for installation challenging required options. The drive is already parameterised to the particular type of electric motor. You only have to make adjustments like the ramp time, minimum/optimum frequency or limitations to the path of rotation.

Variable Speed V-Belt Drives are suitable for our geared electric motor types. Do you want to find out 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 contain 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-tolerant materials, maintenance is minimal. This also offers a positive effect on your operating cost balance.
