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 from the engine just as much as a conventional two acceleration or one rate. This confuses some riders and leads to a mistaken impression of a lack of power.
We can also create fully parameterised drive units 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 Variable Speed Drive engine’s gear ratio as engine speed increases. This enables the variator to keep the engine within its optimum efficiency while gaining surface speed, or trading velocity for hill climbing. Efficiency in this case could be fuel efficiency, decreasing fuel consumption and emissions output, or power effectiveness, allowing the engine to produce its maximum power over a wide range of speeds.
We supply our Electronic Variable Speed Drives prepared for installation challenging required options. The drive is already parameterised to this type of engine. You only need to make adjustments like the ramp time, minimum/optimum frequency or limitations to the path of rotation.
Variable Speed V-Belt Drives are ideal for our geared engine types. Would you like to discover more about our range of geared motors?
And also Variable Speed V-Belt Drives, now you can also obtain Electronic Adjustable Speed Drives, which contain 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 manufactured from corrosion-resistant materials, maintenance is minimal. This also has a positive influence on your operating cost balance.
