How to turn a 2.0hp motor into a 250v generator

I have successfully built a 250v 10,000w generator from a 2 horsepower 2800rpm motor, it's great you can see more on;

There are two simple types of motors designed to run on alternating polyphase current: synchronous motors and induction motors.

The synchronous motor can be likened to a three-phase alternator which would operate in inversion. The inductor magnets are mounted on the rotor and are excited by direct current. The armature winding is divided into three parts and supplied with three-phase alternating current. The variation of these three current waves in the armature causes a magnetic reaction of the magnets and causes the inductor to rotate at a constant speed determined by the frequency of the alternating current of the power supply. Synchronous motors can also be powered by a single-phase power source, if fitted with suitable circuit elements.

If the mechanical load on the motor becomes very high, the use of a synchronous motor is avoided, because if it slows down under the effect of a stress, it eventually stops. An induction motor is then used, the simplest model of which is the cage motor, powered by a three-phase current. The armature of this motor consists of three fixed coils, as on a synchronous motor. The rotor consists of a core in which are inserted a series of large conductors arranged in a circle around the shaft. The three-phase current flowing through the armature windings creates a rotating magnetic field which induces current in the cage conductors. The magnetic reaction between this rotating field and the rotor conductors causes the rotor to rotate. If it rotates at the same speed as the magnetic field, no current will be induced. This is why the rotor must not rotate at a synchronous speed. In general, the rotational speeds of the rotor and the field differ by about 2 to 5 p. 100
