Variable speed belt gear motors are space-saving, continually adjustable drives. In the typical version the central adjustment is made with a hands wheel. Unlike inverter operation the electric motor power remains constant and the torque raises if the acceleration of the electric motor drops.
The variable speed gear unit housing includes a proven symmetrical design. The adjusting pulleys possess a wedge shaped symmetrical cross Variable Speed Belt Gear Motors Speed Reducer Gearbox section with low mass. The form of the pulleys ensures uniform flank pressure and therefore high power transmission, also at high belt velocity.
The result is optimal control behaviour with uniform distribution of forces and minimal energy consumption.
