Variable Speed Drive

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

We can also produce fully parameterised drive models on request. For this, we load a data record that 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 floor speed, or trading swiftness for hill climbing. Efficiency in this case can be fuel effectiveness, decreasing fuel usage and emissions output, or power effectiveness, allowing the engine to produce its optimum power over a wide selection of speeds.

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

Variable Speed Variable Speed Drive V-Belt Drives are suitable for our geared motor types. Do you want to discover more about our range of geared motors?
In addition to Variable Speed V-Belt Drives, you can now also obtain Electronic Adjustable 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 made from corrosion-resistant materials, maintenance is minimal. This also offers a positive effect on your working cost balance.
