Kw and horsepower is often use the brushless dc motor power of the unit, the brushless dc motor in the south of anhui below small make up take you to understand how they are conversion? Horsepower is metric and inch 2 kinds, have a smaller difference between the two, without explanation, should be considered a metric horsepower. In addition, there is a name called & other; Electric power & throughout; , it is equal to the imperial power on numerical. From the physical concept is 1 w = 1 j/s = 1 n & middot; M/s1 horsepower (The metric system)= 735. 499 w = 735。 499 n·M/s, unit horsepower and kw (千瓦)The conversion relation is as follows: 1 kw = 1. 36 horsepower (The metric system); Or 1 HP (The metric system)= 0. 735499 kw1kw = 1。 34 horsepower (Inch); Or 1 HP (Inch)= 0. 7457 kw, roughly 1 kw = 1. 35 Marion or 1 = 0. 75 kw. Memory formula is: horse in kw, four top sa the imperial power symbol with HP; Metric horsepower said there is no unified symbols, Germany with PS, the French use ch or CV, other countries haven't specific provisions, but often use the imperial power symbol. Write here, southern anhui small make up I do not know whether you to kw brushless dc motor and power conversion have detailed understanding?
