What size cable for 90kW 3phase 440v 50Hz motor?
To size cable the amperage must be known. Use the following equation to find amperage. Amps = kW x 1000/1.73 x volts x pf. A standard motor's power factor between 10 to 100 HP is .86 to .92. Amps = 90 x 1000 = 90000/ 1.73 x 440 x .92 = 90000/700 = 128 amps. Motor feeders have to be rated at 125% of the motor full load amperage. 128 x 125% = 160 amps. A 2/0 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 175 and 185 amps respectively.
What is the difference between flange mounted and foot mounted electric motor?
The foot-mounted version is also commonly referred to as B3 motor. The DR motor is available with a NEMA "C-face" flange . The "C-face" flange-mounted motor is a motor type with tapped holes in the flanged end shield.
What size power cable is needed for 30KW 440V 3phase 50Hz induction motor?
Use this formula to find amperage when kW is shown. Amps = kW x 1000/1.73 x Volts x pf. Use a power factor of .85 for the formula. Once the current is calculated re-ask the question for cable size for the calculated current.
