Since the variator keeps the engine turning at constant RPMs over a wide variety 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 velocity or one rate. This confuses some riders and prospective customers to a mistaken impression of a lack of power.
We can also create fully parameterised drive devices on request. For this, we load a data record that you provide in to 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 allows the variator to keep the engine within its ideal efficiency while gaining surface speed, or trading speed for hill climbing. Effectiveness in this case could be fuel effectiveness, decreasing fuel consumption and emissions output, or power effectiveness, permitting the engine to produce its maximum power over a wide variety of speeds.
We supply our Digital Variable Speed Drives ready for installation with all of the required options. The drive has already been parameterised to the particular type of engine. You only need to make adjustments such as the ramp time, minimum/optimum frequency or limitations to the path of rotation.
Variable Speed V-Belt Drives are ideal for our geared electric motor types. Would you like to find out more about our selection of geared motors?
In addition to Variable Speed V-Belt Drives, you can now also obtain Electronic Variable 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.
