Because motor convert the electrical energy in to mechanical
energy so form of energy can be calculate in MECHANICAL
ENERGY THAT IS Horse power

Answer / s. chatterjee

electrical instruments or any type of instruments are rated
as per their output not input. in motor the output is
mechanical energy and it is convenient to express it in
mechanical expression for power i.e. HP.

Answer / vikas

Motor rating is in hp because
it does not take into account
power factor so it acts same as
active power without any multiples
of phases.
1hp= 746w
kw=VIcos a for ac
and VI for dc.
