I want to make a Arduino based speed controller of a 0.5 kW 220 V 2.5 A separately excited DC motor but can't find any motor driver at this voltage range. Please help me to design a hardware for this purpose or to find a motor driver of this voltage level that can be controlled by Arduino with PWM technique

Can you elaborate on the meaning of "separately excited DC motor", because that is not creating a very clear picture of what you have in mind. Do you have even a preliminary idea of how you will drive this motor? We can address the speed control and Arduino interface as a second step.

220 volts DC is an unusual voltage. Are you sure of your requirement?

The hardware should be simple: Plenty of Mosfets that can handle 220V @ 2.5A. Include a protection diode, and feed the PWM signal into the gate.

For these types of motors the power side is usually a SCR/diode bridge which rectifies the mains voltage. Voltage control is by phase control of the SCRs. the inductance and inertia of the motor does not require mosfet control.
Lots cheaper and simpler than a PWM driver though you do need to synchronise to the mains voltage (not hard) and need to provide isolation between the control and power side (pulse transformer or optoisolators)

The rated voltage of the motor is 220 v, we are going to control the speed up to rated hence need to control the voltage from low to a voltage upto rated, to get rated speed of the motor at no load condition

We want to control it by 4 quadrant chopper

Separately excited means a DC motor having a field excited from a separate source. The field will be kept fixed. We want armature voltage control using a 4 quadrant chopper, there are different drivers available like L298N in market but they cannot handle this large source voltage, hence we need help
