Variable speed belt gear motors are space-saving, continually adjustable drives. In the typical edition the central adjustment is manufactured with a hand wheel. Unlike inverter operation the engine power remains continuous and the torque increases if the velocity of the engine drops.
The variable speed gear unit housing includes a verified symmetrical design. The adjusting pulleys possess a wedge designed symmetrical cross section with low mass. The shape of the pulleys ensures uniform flank pressure and for that reason high power transmission, actually at high belt rate.
The Variable Speed Belt Gear Motors Speed Reducer Gearbox effect is optimal control behaviour with uniform distribution of forces and minimal energy consumption.
