Because 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 as much as a conventional two acceleration or one speed. This confuses some riders and potential clients to a mistaken impression of a lack of power.
We can also produce fully parameterised drive products on request. For this, we load a data record that 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 optimum efficiency while gaining floor speed, or trading acceleration for hill climbing. Performance in this case could be fuel performance, decreasing fuel consumption and emissions output, or power effectiveness, permitting the engine to create 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 motor. You only have 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 all of our geared engine types. Do you want to find out 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.
