Adjustable Speed Drive Dealers in Pune

The spring loaded 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 diameter pulley when in operation. As the centre distance changes, the variable speed belt is pulled in or out between the two flanges of the spring loaded pulley, thus changing the effective running diameter of the pulley and the speed variation is achieved of the fixed diameter pulley. The speed variation ratio achieved is 1:3 and in combination with fixed diameter pulleys of various diameters, practically full middle speed range is covered.
