Then it is not a three phase motor.
Interchanging the red and black leads in the motor's motor junction box will reverse the direction of rotation on the motor.
If you mean to reverse the direction of a three phase motor, you just switch any 2 leads. switch 1 and 2, or 2 and 3, or 3 and 1.
Connecting Phase A, B and C to the motor leads will make a 3 phase motor run in one direction while interchanging any two will make the motor rotate in the opposite direction.
how will you start 3phase inuction motor using star delta stater
Connecting is simple. The main issue is what kind of motor do you have? Batteries are DC. Therefore the motor must be DC or a universal motor, or a permanent magnet DC motor. The motor voltage and current requirements must match the battery's voltage and ampere-hour rating. A standard DC motor has 4 leads A universal motor has 2 leads A permanent magnet DC motor has 2 leads. The motors with 2 leads are easy: + and -- The 4 lead motor: 2 leads are "field" (F1 F2) 2 leads are armature (A1 A2) one of each goes to + (F1 A1) one of each goes to -- (F2 A2) The motor must be very small in horsepower to work off a battery. There are other more complex DC motors with more leads than 4, but there are NOT going to run on a battery.
Reverse any two line leads connected to the motor will reverse the directional rotation of the motor
Reverse any two line leads connected to the motor will reverse the directional rotation of the motor
the three phase dc motor never seen yet motor eaither 3phase m/r or dc motor.

the power leads were wired wrong
Into units of what?
Interchanging the red and black leads in the motor's motor junction box will reverse the direction of rotation on the motor.
From the bottom of the motor contactor's heater block you connect the motor's leads to T1, T2 and T3. If the motor rotates in the wrong direction reverse any two leads on the bottom of the motor's contactor heater block.
If you mean to reverse the direction of a three phase motor, you just switch any 2 leads. switch 1 and 2, or 2 and 3, or 3 and 1.
How to calculate a cable size of 3kw motor
If it is a three lead 3-phase motor, it is easy: connect the incoming three leads randomly to the three leads on the motor (one to one) so that there are a total of three splices. The motor will run but possibly in reverse If it runs in reverse, switch any two of the three splices ---- If the motor has more than three leads, and they are not marked, it is much more difficult. You will have to have a working knowledge of how to test the leads and compare the results with the information given on the nameplate
The motor connection diagram should be on the inside cover plate of the motor's junction box cover. To reverse the motor direction just reverse the starting winding leads while leaving the running windings just as they are. The starting winding numbers are sometimes numbered 1 and 4.
