Variable Speed Drive

Because 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 speed or one acceleration. This confuses some riders and network marketing leads to a mistaken impression of too little power.

We can also create fully parameterised drive systems 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 enables the variator to keep the engine within its ideal efficiency while gaining floor speed, or trading velocity for hill climbing. Effectiveness in this case can be fuel effectiveness, decreasing fuel intake and emissions result, or power effectiveness, permitting the engine to create its optimum power over a wide range of speeds.

We supply our Electronic Variable Speed Drives prepared for installation challenging required options. The drive has already been parameterised to this type of electric motor. You only need to make adjustments like the ramp time, minimum/optimum frequency or limitations to the direction of rotation.

Variable Speed V-Belt Drives are suitable for our geared motor types. Do you want to find out more about our selection of geared motors?
Along with Variable Speed V-Belt Drives, now you can 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.
