Variable Speed Belt Gear Motors Speed Reducer Gearbox adjustable speed belt gear motors are space-saving, continually adjustable drives. In the typical version the central adjustment is manufactured with a hands wheel. Unlike inverter procedure the electric motor power remains constant and the torque improves if the rate of the engine drops.
The variable speed gear unit housing includes a proven symmetrical design. The adjusting pulleys have got a wedge designed symmetrical cross section with low mass. The shape of the pulleys guarantees uniform flank pressure and for that reason high power transmission, even at high belt speed.
The effect is optimal control behaviour with uniform distribution of forces and minimal energy consumption.
