Because the variator keeps the engine turning at constant RPMs over an array of vehicle speeds, turning the throttle grip will make the moped move faster but doesn’t change the sound coming from the engine just as much as a conventional two speed or one acceleration. This confuses some riders and potential clients to a mistaken impression of a lack of power.
We can also create fully parameterised drive models on request. For this, we load a data record which you provide into 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 optimal efficiency while gaining surface speed, or trading quickness for hill climbing. Effectiveness in this case could be fuel performance, decreasing fuel usage and emissions result, or power effectiveness, enabling the engine to produce its maximum power over a wide range of speeds.
We supply our Digital Variable Speed Drives ready for installation challenging required options. The drive has already been parameterised to this type of motor. You only need to make adjustments such as the ramp time, minimum/maximum frequency or restrictions to the direction of rotation.
Variable Speed V-Belt Drives are suitable for our geared motor types. Do you want to discover more about our selection of geared motors?
As well as Variable Speed V-Belt Drives, now you can 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.
