AI Technical Summary

Technical Problem

In brushless field coil and permanent magnet motors, the use of brushes to supply power to rotor coils is inconvenient, and existing rewinding methods do not effectively manage power distribution between field coils and permanent magnets to achieve desired power levels.

Method used

Rewinding the motor armature with two intertwined insulated wires to create two separate coils, allowing for independent and combined energization to achieve different power outputs while maintaining consistent magnet power, thereby enabling flexible power management.

Benefits of technology

This solution allows for a ½ HP motor operation when both coils are energized together and % HP operation when coils are energized separately, effectively managing power distribution and maintaining consistent magnet power, enhancing motor flexibility and efficiency.

Abstract

A two in one motor comprises a field coil armature which is wound with two insulated wires which are half the size of the wire of the original motor. When power is applied to one of the coils the power of the motor is reduced: when both coils are energised together the power of the motor is the same as the original coil. The method is applied to an existing TEFC motor comprises a brushless field coil and a permanent magnet rotor, which is dismantled and reassembled.

Description

PAGE-01 A brushless field coil and permanent magnet rotor, half horse power, 90 volts DC, 2.5 ampere TEFC motor is taken. If a rotor coil is used then there is the need for using the brushes to supply power to the rotor coils. Therefore, it is more convenient to use field coils and rotor permanent magnet. The motor is taken apart and the 8 gauze wire from the field coil armature is removed. Two 16 gauze intertwined insulated wires are taken and the armature is rewound with this wire in such a way that is makes two coils in one. When power is applied to one coil, the motor power is reduced to quarter horse power, 90 volts DC and 2.5 amp and when the second coil is energized it gives the same power. Thus the coil are separate. The magnet power remains the same. The motor is reassembled and when both the coils are energized together it is a ½ HP motor and when the coils are separately energized in turn it is a % HP motor.

Claims

The salient features of this motor is that, one - it has two windings on the armature, one inner and one outer, two - it has two commutators at the front and the rear of the armature, three * it has eight brushes 4 for the front commutator and 4 for the rear commutatorThe writer is claiming a patent for this motor because it has the foilowing functions,1 the motor was constructed from a half horsepower motor into two quarter horsepower motors. Each quarter horsepower motor works independently and aiso works in tandem as a half horsepower motor,T.When one part of the motor is fed power to rotate the shaft it simultaneously generates approximately the same amount of power to be extracted from the other part by transformer action and vice versa. Thus, the 2 - in -1 Motor works both as a motor and a generator at the same time.

3. using this motor and power storage capacitors electrical positive feedback was experimentally successful and proven4. when positive feedback was used with the two part motor, then via power storage capacitors, the motor worked autonomously for about half an hour and slowly stopped. No further experimental test was done due to time limitation.Due to the above mentioned features and functions the writer is asking the esteemed patent office to issue a patent for this invention and oblige him thereby
