Trickle Impregnation Machine

Additional Details

Trickle Impregnating Machines are suitable for automatic impregnating of stators and rotors by trickle process. Stators and Rotors are heated to pre-determined temperature and then trickled with varnish (Resin + Hardener) and cured until it hardens. They are then ready for unloading manually.

They are rotated by chain drive which rotates the spindles mounted on rotating / indexing table at an appropriate speed suitable for trickling. Indexing Table is rotated by brake motor with gearbox and limit or proximity switches.

Stators and Rotors are pre heated and cured while passing through the pre heating zone and post heating zone. Radiation type electric heaters do heating in pre-heating and curing zone with temperature control by Digital Temperature Indicating Controller with proportionate temperature control. Both the zones are insulated to minimize heat loss.

Varnish is fed by peristaltic tube pump driven by D.C. motor with variable speed control to control varnish quantity according to the models. Total cycle is automatic except for loading and unloading.

Rotating spindles are mounted on table driven by electric motor and gearbox. Heating time can be adjusted with the help of timer and indexing. Electric motor, gearbox and suitable chain sprocket drive all spindles.
