The supply won't have to work as hard. It is perfectly acceptable, for example, to use a 1A, 12v supply to supply a 12v, .5A load. The current rating indicates the ability of the supply to dissipate heat caused by the current flowing. If the load current is above the power supply current rating, the power supply will overheat.
No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
A DC power supply supplies directional current in an electric motor. This is significant because many motors run on directional current, or DC power; it's easier to convert to kinetic energy than alternating current (AC), which is generally used to transmit power over long distances.
Motors which have their electrical power supply taken from batteries.
Only a DC motor uses direct current, and the reason is that it is the only supply available. There are also plenty of AC motors used when there is an AC supply. DC tends to be used for low-power devices like fans in electronic equipment.

It is generally not recommended to use a power supply that exceeds the current rating of the device you are powering. In this case, using a 24V 3A power supply instead of a 24V 2.3A could potentially overload the device and lead to damage or malfunction. It is safer to use a power supply that matches or slightly exceeds the current rating of the device.

No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
The current rating for a relay used with motors depends on the motor's power requirement. As a general guideline, a relay for a motor should have a current rating at least as high as the motor's full load amperage to ensure proper operation. It is recommended to select a relay with a current rating slightly higher than the motor's requirement to prevent overheating and ensure reliable performance.
As the name implies, motors are resistive-inductive loads, which means that their load current must lag the supply voltage. By definition, a lagging power factor is the cosine of the angle by which the load current lags the supply voltage.
Generally, yes. If your devise will only draw 80mA, it will do it whether it is connected to a supply that is capable of supplying 300mA or 800mA. The amperage rating on the power supply is the highest current that it is rated for. It will easily and safely provide less current. The load that is connected to the power supply will determine the actual amount of current.

Yes. The voltage is the same on each. The ma rating of the power supply is the current the supply can handle before burning up. So if your appliance is designed to work on an 800ma supply, an 850ma supply will do fine.
Your computer gets it's Direct Current from a power supply which transforms alternating current into DC. They will have a motor inside them,. but's only there to power the fan which ventilates the PSU.
