FIELD OF INVENTION: The present invention relates to a device to increase revolution per minute of any electric motor. Particularly, the present device is able to increase the rptn of existing motor 5 to 50 tunes. BACKGROUND: Hiectric motors are basically used to convert electric energy into mechanical energy for performing various task and activities in various fields. Therefore, various types of motors, which are characterised on the basis of power, revolution per minute, load carrying capacity, exist in the industry and day-to-day work. In previous years, various models of motors have been launched which are very specific and directed for specific task and activity. Some time the motors are selected for getting high load carrying capacity, less noise, higher rpm etc. Industrial motors come in a variety of basic types. These variations are suitable for many different applications. Naturally, some types of motors are more suited for certain applications. The motors available are, • AC Motors • DC Motors • Brushless DC Motors • Servo Motors • Brushed DC Servo Motors • Brushless A ( ' Servo Motors • Stepper Motors • Linear Motors AC Motors The most common and simple industrial motor is the three-phase AC induction motor, sometimes known as the "squirrel cage" motor. The disadvantages associated with these are • Expensive speed control • Inability to operate at low speeds • Poor positioning control Expensive speed control Speed control is expensive. The electronics required to handle an AC inverter drive are considerably more expensive than those required to handle a DC motor. However, if performance requirements can be met - meaning that the required speed range is over l/3rd of base speed -- AC inverters and AC motors are usually more cost-effective than DC motors and DC drives for applications larger than about 10 horsepower, because of cost savings in the AC motor. Inability to operate at desired speeds Standard AC motors should not be operated at speeds less than about 3 to 10 times of base speed. This is due to thermal considerations. A DC motor should be considered for these applications. Poor positioning control Positioning control is expensive and crude. Even a vector drive is very crude when controlling a standard AC motor. Servomotors are more appropriate for these applications. DC Motors The bnished DC motor is one of the earliest motor designs. The disadvantages associated with these are • Expensive to produce • Can't reliably control at lowest speeds • Physically larger • High maintenance • Dust • Distortion of brushes Presently the motors are available, which can run at any desired rpm efficiently. The size of motors have to designed for specific load and rpm, at the same time the rpm can be controlled by varying input voltage by means of auto transformer/autotransformer or any other control means. Hence, manufacturing a motor with such features involve very high cost. There is no such device known or available, which enhances the rpm of motor, without utilizing such voltage transformer, or rheostat, means. In order to overcome the above-said drawbacks the applicants have come out with a novel device, which can be mounted with any motor available in the market and capable to increase its rpm for at any desired level.
