The capacitor is used to create a second phase from the single phase power source and it is the interaction between these two phases that causes the motor to turn.
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
No, but certain types of AC single phase motors need a "startup capacitor" to make sure they start turning in the right direction when power is applied.
A capacitor in its simplest form is merely two electrically conductive plates separated by an insulator from each other. As such the capacitor will block any DC voltage from passing through it, up to the electrical dielectric strength of the insulator. The capacitor will accept a DC charge and an electrical field will exist between the plates of the capacitor. The capacitor will retain this charge until it either leaks away via the high electrical resistance of the insulator, or is intentionally discharged. When an AC or varying voltage is applied to a capacitor, a varying electrical field is set up between the plates of the capacitor. This will thus pass through the capacitor, and can be seen on the opposite plate. Thus, a capacitor will pass an AC voltage. Now,as to the question, " application of Capacitor". One of the oldest and most useful of capacitor applications is filtering or smoothing the output of an AC to DC power supply. In this supply, an AC voltage is rectified by a diode into a varying DC voltage. A capacitor is placed across the output, and serves to supply voltage or "fill in" the output whenever the output voltage is less than the capacitor. The capacitor subsequently recharges on the next cycle and repeats the process. Thus, the output voltage of the power supply is smoothed out.
AC can pass through a capacitor. The higher the frequency of AC the lower the reactance (like resistance). The current and applied voltage are 90 degrees out of phase the current leading the voltage by this amount.
A fixed capacitor can be used for power-factor correction for a single-phase ac appliance such as an induction. One of these can also be used to suppy a phase-altered current to the starting winding on the motor. In electronics fixed capacitors are used in shunt for decoupling, which earths any ac voltages on a dc-carrying wire, or in series for blocking dc and passing ac signals between stages in equipment.
The value of the capacitor for a 1hp AC motor depends on the specific motor design and manufacturer guidelines. It is important to consult the motor's documentation or contact the manufacturer to determine the correct capacitor value for proper motor operation.

how to connect power capacitor with 3 phase motor
If you mean run capacitor, as in the run capacitor for an AC motor, it is usually a round or oval cylinder.
Some AC motors are designed to start running as soon as electricity is provided. Other AC motors are designed for a specific purpose and do not start on AC current. They will RUN on AC, but require a DC current to start. Here's where the capacitor comes in. It stores DC power that, when released, starts the motor turning. At this point, AC current will nicely run the motor.
A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding. A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.
See Discuss Question below.

The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
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.
A run capacitor and a starter capacitor are not the same thing. A run capacitor is energized the entire time the motor is running, and a start capacitor is not. A run capacitor is one that changes the current on the windings of a single phase AC induction motor to create a rotating magnetic field to energize a second-phase winding. A start capacitor increases starting torque, allowing a motor to be turned on rapidly. It stays in the circuit only long enough to bring the motor to 3/4 of full speed. Some motors then continue to run with a run capacitor.
