Daikin EWADC12C-XL [106/304] Compressor the single screw compressor is of the semi hermetic type with an asynchronous three phase two pole motor directly splined on the main shaft the suction gas from the evaporator cools the electric motor before entering the suction ports there are temperature sensors inside the electric motor which are completely covered by the coil winding and constantly monitor motor temperature should the coil winding temperature become very high 120 c a special external device connected to the sensors and to the electronic controller will deactivate the corresponding compressor there are only three moving rotating parts and there are no other parts in the compressor with an eccentric and or alternating movement the basic components are therefore only the main rotor and the two satellites that carry out the compression process meshing perfectly together the f3b and f4a compressors are fitted with two satellites arranged horizontally to the screw compression sealing is obtained thanks to a su
