Contactors and Control Circuits

These motors run on a 400v 3 phase supply, and can run using less current than an equivalent single phase motor. 3 phase direct on-line motors consist of three sets of windings (one for each phase), connected in delta. These motors are connected directly to either a 3 phase switch or a contactor (as a method of control). fig 6. 3 PHASE STAR ...
