Manufacturer of 5 HP Brushless DC (BLDC) Motor in China, our motors can be designed at voltage range from 24V to 380V DC, cover a output power range from 1.5KW to 10KW, its torque range on continuous duty is 3-20Nm, on intermittent duty up to 7.5-50Nm.
For a 1-phase supply with power rating in kilowatt (kW): For a 1-phase supply with power rating in horsepower (hp): Note that the motor rated full load current is specified on the motor datasheet and stamped on the motor nameplate. However, this calculator is useful when only the motor rating is available and an estimate of the current is required.
RLA - "Running Load Amps" - current drawn during normal operation of electric motor. FLA - "Full Load Amps" - amount of current drawn when full-load torque and horsepower is reached for the motor.FLA is usually determined in laboratory tests.Note! - in the calculator above FLA is RLA + 25%. 1 hp = 0.745 kW; Related Mobile Apps from The Engineering ToolBox ...

How to convert horsepower to kilowatts [HP to kW]:. P kW = 0.745699872 × P HP. How many kilowatts in a horsepower: If P HP = 1 then P kW = 0.745699872 × 1 = 0.745699872 kW. How many kilowatts in 87 horsepower: If P HP = 87 then P kW = 0.745699872 × 87 = 64.875888864 kW. Note: Horsepower is an imperial or United States customary unit of power.Kilowatt is a metric unit of power.
At the other hand, Motor has fixed Power factor, i.e. motor has defined power factor (p.f) and the rating has been mentioned in kW on Motor nameplate data table.That's why we are rated Motor in kW or HP (kilowatts/ Horsepower) instead of kVA. in more clear words, Motor only consume active power and provide mechanical power in HP or kW at motor shaft.

Motors of higher speed usually take a lower current than that shown in the table; while motors of lower speed usually take higher current. Wide variations from these figures can arise, especially on single phase motors, and engineers should, whenever possible, determine the actual f.l.c from the motor rating plate in each case. Single Phase Motors
Mar 01, 2017· DEFINITION Horsepower (hp) The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/...
