Variable Speed Drive

Since 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 just as much as a conventional two velocity or one swiftness. This confuses some riders and network marketing leads to a mistaken impression of too little power.

We can also generate 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 the engine within its optimal efficiency while gaining ground speed, or trading speed for hill climbing. Performance in this case can be fuel efficiency, decreasing fuel usage and emissions output, or power effectiveness, permitting the engine to create its optimum power over an array of speeds.

We supply our Digital Variable Speed Drives ready for installation with all of the required options. The drive is already parameterised to this type of engine. You only have to make adjustments such as the ramp time, minimum/optimum frequency or limitations to the path of rotation.

Variable Speed V-Belt Drives are suitable for our geared motor types. Would you like 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 class asynchronous motor, and a NORD gear unit.
