- three-phase motor: Swap the connections of any two phases to the motor.
- single-phase motor: Usually this can be achieved by reconnecting the starting capacitor from one motor winding to another.
Another Answer
As you have no access to the motor's phases, you must interchange any two of the three line conductors.

Why speed of the induction motor falls when load is increased?
As the load increases, the speed reduces to deliver the increased torque required.
Why short circuiting rings are used in squirrel cage motor?
Squirrel Cage motor is a kind of Induction Motor. The reason an induction motor sometimes refered to a rotating transformer is because the stator (Primary windings in a transformer), which is powered to set up a magnetic field induces a current in the armature coils (secondar coils in a transformer). However, instead of giving an electrical power output, the coil is short circuited to produce mechanical output (torque in this case)
What would cause a table saw motor to reverse itself while running?

When the screwdriver motor changes direction?
The magnet is the stator part of the motor,either as a permanent or an electromagnet.It doldrums the rotor past of the motor towards it causing the rotation.
How does a Variable speed transmission work?
Assume a 3 phase AC Induction motor. The speed of the motor is derived by the formula N = (120/f)/P. N speed, f - frequency, P number of poles. In an induction motor P is fixed by the winding. f system frequency. Variable speed drives change the system frequency so that the speed (N) can be varied. Drive is a power electronic device through which the system frequency can be varied
Reverse direction of singlr phase ac induction motor?
The direction of a singular phase induction ac motor can be reversed by switching the capacitor in relation with the motor windings. When started in the reverse direction, the motor will maintain the same torque level that it had in the forward direction.
How can you reverse the direction of rotation in an induction motor?
A single phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.
How do you change the direction of a 3-phase induction motor?
Reverse any two line leads connected to the motor will reverse the directional rotation of the motor
How can a three phase induction motor reverse direction of travel without changing input phase?
A three-phase induction motor can reverse direction of travel by swapping any two of the three input phases. This changes the rotating magnetic field direction, causing the motor to rotate in the opposite direction. No change to the input phase sequence is required.
How do you reverse single phase ac motor to generator?

In induction motor the will the direction of the rotor will be in the direction of the current?
The direction an induction motor will turn depends upon the direction of the rotating field setup by the winding. Remember in AC the direction of the current reverses itself 120 times every second for a 60 hz system. So no it will not turn in the "direction" of the current.
Which motor run in both direction?
Trick question: all motors do if you invert the polarity of input.CommentNot a trick question! In the case of d.c. motors, for example, you have to reverse the polarity to either the field or the armature -not to both. If you reverse it to both, it makes no difference to the direction of rotation! For a three-phase induction motor, you must interchange any two line conductors.
What is the standard direction of rotation of electric motor?
standard direction of rotation of an induction motor is counterclockwise when looking from the front end i.e. non-driving end of the motor.
Reverse direction on a 480 ac motor?
Reverse any two of the lead wires at the motor junction box.
How do you change the direction of 3 phase motor?
Reverse any two line leads connected to the motor will reverse the directional rotation of the motor
How do you forward direction on a single phase induction motor?
A motor does not have a forward or reverse direction like a vehicle. Electrical terminology is clockwise or counter clockwise rotation determined by looking from the opposite drive end of the shaft. That said, a split phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor's directional rotation can be changed by reversing the connections of either the start winding or the run winding but not both.
What happens to cooling if the rotation of an induction motor changes?
Cooling remains same irrespective of the motor rotational direction.
