Changing Motor Rotation 6 Steps Instructables Step 2: locking out motor. the first and most important step in changing motor rotation is to lock out the motor. this is done by disconnecting the motor at the nearest power source and locking that connection open. it is important to write all information on the lockout tag and include it with the lock on the disconnect. Step 2: functioning. the direction of rotation is controlled by means of a circuit known as 'h bridge', which is already integrated into the pwm controller. this is how it is known for its shape similar to the letter h. first we will energize the system with 220vac because from the same pcb we will control the 15vac transformer and in turn a.
Changing Motor Rotation 6 Steps Instructables How to modify a micro servo motor (sg90) for continuous. Arduino digital pin#7 and 8 are used to control the motor rotation direction. connect arduino digital pin#7 to pin#7 of l293d motor driver and pin#8 to pin#2 of l293d. now connect your motor to pin#3 and 6 of l293d. ground pin#4 and 5 of l293d channel 1. arduino can be powered from personal computer of laptop usb port. It is currently set at 1000 pulses which means that on a 200 step per revolution motor, the motor will make 5 complete turns. this can be adjusted as high or low as necessary for your project. if we had set the rotation to 20, then the motor would move 20 steps which corresponds to 20 200ths of a full rotation or 18 degrees. 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.

Causing a three phase motor to turn the other way is always possible by reversing any two phases. but that does not mean the motor will work well, or that it will even survive the change. for example, if you change the direction of rotation, you also change the direction in which forces act on the motor bearings. If you swap any two corners and follow the points a, b and c you'll go in anopposite direction. swap two more corners and you're back to the original rotation. this is what it looks like. the black arrow is the flux produced by the three phase windings: clearly, if yellow phase were swapped with blue phase the rotation would be opposite.
