3 Phase Motor Kw Rating Chart

3 Phase Motor Kw Rating Chart - Web typical single phase & three phase motor data: The information in this chart was derived from table 50.1 of ul standard 508a. Web 45 rows useful motor technical information. Consumption is dependent on the kw rating of the motor,. Web the tables are a guide only and based on 4 pole motors of average efficiency and power factor. The tables are based on motors of approximately 1450rpm of average efficiency. Force cooled roller table motors frames : 90s to 355lx rating (kw) : 1 hp (english horse power) = 745.7 w = 0.746 kw = 550 ft lb/s = 2,545 btu/h = 33.000 ft lb/m = 1.0139 metric horse power ~= 1.0 kva. 0.18 to 55.0 poles :

It Represents The Efficiency Of The Motor In Converting Electrical Power Into Mechanical Power.

To determine the correct current transformer rating, multiply the full load amperes by a factor of 1.25. While motors of lower speed usually take higher current. Web accurate motor data will be given on request at the quotation phase. Wide variations from these figures can arise, especially on single phase motors, and engineers should, whenever possible, determine the actual full load current from the motor rating plate.

Web Technical Data Are Subject To Change!

Motors of higher speed (2 pole) usually use less current than that shown in the table while motors of lower speed (6 pole or more) usually use more current. 1 hp (english horse power) = 745.7 w = 0.746 kw = 550 ft lb/s = 2,545 btu/h = 33.000 ft lb/m = 1.0139 metric horse power ~= 1.0 kva. B3, b5, b14 & combinations protection : Amp rating = (power rating × 746) / (√3 × supply voltage × power factor) where power factor is the ratio of the actual power (watts) to the apparent power (va) supplied to the motor.
