    @Dnyanesh if you want to use a motor with AC as well as DC supply, a universal motor may be the best choice. Universal motors are available in a wide range of speeds and ratings. There are universal motors, easily available in the market, which provide speed as high as 10,000 RPM. So, you can easily get one with 5,000 RPM and appropriate ratings. However, you should also consider other factors such as required power rating and torque rating when a buying a motor.
    About the heating problem you stated, if you are using a custom build motor you can provide some cooling arrangement to it. The most simple cooling arrangement for a motor may be using a shaft mounted or external fan. Also, if you have a custom build motor, make sure you have used the winding wire of proper diameter. Copper losses occurring in the winding also constitute to the heat generation.
