inverted induction motor

slip ring induction motor

shunt motor

series motor

it is likely to burn out quickly unless immediately disconnected

it will start, but very slowly

it will make jerky start with loud growing noise

remaining intact fuses will be blown out due to heavy inrush of current

will stall immediately

will keep running though with slightly increased slip

may either stall or keep running depending on the load carried by it

will become noisy while it still keeps runnings

Motor will run as 2 phase motor and perfroms normally

Will continue to run on 2 phases, but fails to take load

Continue to run on 2 phases, draws excess current, winding likely to burn

Run at reduced speed and can take only 2/3 of the load

The new motor will be overheated

The new motor is better suitable for this work

The efficiency and the power factor will become low

The new motor has a longer useful working life and efficiency
