Variable Speed Drives

Swati variable speed drives are designed for use in presses, packaging machines, printing machines, textile machines, machine tools, auto claves, pumps for viscous liquids, and conveyor belts. The variable speed pulley is mounted on the shaft of the electric motor which is firmly fixed on the motor slide base or swinging base plate and moved towards or away from the fixed pulley when in operation. As the centre distance changes, the wide section V belt is pulled in or out between the two flanges of the spring loaded (variable speed pulley), thus changing the effective running diameter of the pulley and the revolution of the fixed pulley. The speed variation ratio achieved is 1:3. In combination with fixed pulleys of various diameters, practically full middle speed range is covered.
