If you are concern about the rotation of the 3 phase motor, all you have to do is connect the power to the three terminal wires, make sure connections are tight, insulate one of the connections properly, the other two just put enough wrap insulation to prevent shortening of the power phases. Bump the motor, that is start it and quickly shut the power of, this way you can check for rotation, if motor is turning in the proper direction, proceed with a thorough insulation of the remaining two connections. If the motor is not turning in the proper direction, switch the connections that were no thoroughly taped, bump motor again it should have changed direction, proceed with taping up the connections.

If there is a chance of damaging equipment connected to the motor by bumping it or a panel that has multiply motors connected to it there is a phase sequence meter that can be used to check proper phase sequence. On three phase service rebuilds this meter works great. Get the phasing right at the CDP and all or the motors that are connected to it will be in the right rotation.

Open ended induction motor - i assume you are talking about split phase induction motor. With these motors old style speed controlling method using external resistors can be used. However this is now obsolete.

Yes, that is one of the major advantages of a three-phase induction motor.
That indicates a fault in the induction motor.

A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.

Single phase Induction motor
single-phase induction motor is used in ceiling fan.
why three phase induction motor is delta connected
capacitive start motors start by themselves however a normal single phase induction motor requires a starter motor to 'kick-start' the motor into action.
One of the disadvantages of the 3 phase induction motor is that it requires a three wire supply. The other disadvantage is that the 3 phase induction motors have poor starting torque and high have in the rush currents.
