A three section motor is used in this software as this is requires a powerful motor which could cope with a heavy load. The 3 section motor is powered via the primary 3 phase strength. power through the main’s runs thru two fundamental contactors. while the primary contactor is switched on and the second contactor is switched off, power runs via the primary contactor to the winding of the motor which moves the motor inside the forward direction.

when the second one contactor is switched on and the primary contactor is switched off, power runs thru the second contactor to the winding of the motor which actions the motor within the backward direction. word that the wiring is different for the reverse course.
