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