1 hp single phase motor is more likely to get hot thsn inone hp 3 phase
motor its true or false? If true why?
Answers were Sorted based on User's Feedback
Answer / subhasish
True, because for single phase motor the current rating is higher than that of a three phase motor for same power consumption. Therefore the current density is also high for single phase motor and as we know, higher the current density higher it will be heated.

Answer / suresh
true. because 1 hp single phase mortor there are only one
phase and one neutral in alternative method . where there
are 12 coils
