Since the variator keeps the engine turning at continuous 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 network marketing leads to a mistaken impression of a lack of power.

We can also produce 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 diminish the 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. Effectiveness in this case could be fuel efficiency, decreasing fuel intake and emissions output, or power performance, enabling the engine to produce its optimum power over an array of speeds.

We supply our Electronic Variable Speed Drives ready for installation challenging required options. The drive has already been parameterised to this type of engine. You only have to make adjustments such as the ramp time, minimum/optimum frequency or restrictions to the path of rotation.

Variable Speed V-Belt Drives are ideal for our geared engine types. Do you want to find out more about our selection of geared motors?
Along with 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.

While others have actually blogged about the subject of Variable Speed Drive, my hope is that this article brings an one-of-a-kind viewpoint.
