How To Change Rotation 3 Phase Electric Motor This is how to change motor direction manuallywe all know that the direction of rotation of a 3 phase motor can be changed by reversing two of its stator lea. The phases have a phase shift of 120 degress called electrical phase angle, meanwhile the windings on the motor are also shifted by 120 deg mechanical angle. in a such way, when the current passes trough windings the rotating magnetic field is formed, which is the sum of all three vectors.

How To Change 3 Phase Motor Rotation Direction Electreca Youtube Steps to change the direction of a three phase electric motor: disconnect power: turn off and lock out the power source to ensure safety. identify motor leads: identify the three motor leads or wires. these are typically labeled u, v, and w or a, b, and c. note the initial rotation:. The direction of rotation for the motor shaft of an ac motor is defined in iec 60034 8 as either cw (clockwise) or ccw (counter clockwise), when looking into the motor shaft. the direction of rotation of a three phase ac motor can be changed at the terminal box. this is done by interchanging two of the line cables, e.g switch l1 and l2. Check rotation by jogging or bumping. apply power to the motor leads for a short period of time, enough to just get motor shaft to rotate a slight amount to observe shaft rotating direction. 4. three phase interchange any two (2) of the three (3) line leads.
