D

d

D = diameter of DRIVEN pulley

D = diameter of DRIVER pulley

C

C = distance between sha s

To Determine RPM for Driven Pulley

d x Motor RPM D

Speed of Driven Pulley in RPM =

Conver ng Electrical Horsepower to Kilowa s

One electrical horsepower is equal to 0.746 kilowa s.

1 hp (E) = 746 W = 0.746 kW

So, the power conversion of horsepower to kilowa s is given by:

P (kW) = 0.746 x P (hp)

Example: Convert 10 HP to kW:

P (kW) = 0.746 x 10hp = 7.46 kW
