How many amps is a 11kw motor?

How many amps is a 11kw motor?

Full Load Current – 22.5A at 400V.

How do you calculate the starting amps on a motor?

You can multiply the code (amps) times the Horsepower of motor to determine starting amps. Find a list of codes and the amps here. Cycles (Hz) – All U.S. electrical appliances run at 60 cycles per second.

How do you calculate current from 3 phase current?

Three Phase Current – Calculation

  1. kW = kVA x pf.
  2. kVA = kW/pf.
  3. kVA = kW / power factor = 23/0.86 = 26.7 kVA (26700VA)
  4. Current = VA / voltage = 26700 / 230 = 116 A.
  5. VLL =√3 x VLN
  6. VLN = VLL / √3.
  7. kVA = kW / power factor = 12 / 0.86 = 13.9 kVA (13900 VA)
  8. Current = VA / voltage = 13900 / 230 = 60 A.

Motor horsepower Full load amps 230VAC Full load amps 460VAC
2 6 3.0
3 9 4.5
5 15 7.5
7.5 22 11

How many amps does a 3 HP 3 phase motor draw?

AMP DRAW BASED ON HORSEPOWER

HP 1 Phase Amps 3 Phase Amps
115 volt 575 volt
3 34 3.9
5 56 6.1
7-1/2 80 9

How is inrush current calculated?

Inrush current calculations: Approximately inrush current I(peak) is equal to the ratio between the root 2 times of maximum applied voltage to DC winding resistance. This calculation gives you the approximate value of the inrush current to understand.

What are starting amps?

Cranking amps (current), also known as ‘CA’, starting amps or starting current, is the amount of power (electrical current) a battery can discharge and sustain for at least 30 seconds during normal climate conditions of 32 degrees Fahrenheit or 0 degrees Celcius.

How much current does a 3 HP motor draw?

AMP DRAW BASED ON HORSEPOWER

HP 1 Phase Amps 3 Phase Amps
115 volt 208 volt
3 34 10.6
5 56 16.7
7-1/2 80 24.2

What size breaker do I need for a 3 phase motor?

Breaker size must be rated for a minimum of 125\% of the full-load current of the motor it is protecting, rounded up to the next standard breaker size. For example, the full-load current of a 5 HP motor at 460V is 7.6 Amps. The breaker must be sized for 7.6 * 1.25 = 10 Amps .

How to calculate the power consumption of 3 phase 30hp motor?

Calculate the total power consumption of the 3 Phase 30HP motor is operating for 38 days at 70\% of the full load and the motor is operated at 14 hours per day. For calculating electricity bill just multiply the total power consumed by the motor with the per kWh price.

What is starting current of an AC motor?

Definition & Formulas. Starting & Running current are the three important factors for the rating of AC induction motor. Starting Current, sometimes abbreviated as I start in electrical engineering, is a measure or rating of how much current required for a single or three phase AC motor to get started. It’s generally, four times of running current.

How much is 1 hp in kW?

Note: 1 HP is equal to 0.746 kW. Here the HP rating or kW rating can be found at the motor nameplate details. Note: The motor nameplate details will be placed near to the motor terminal box. The above calculations are suitable for DC motor, AC single phase motor and 3 phase motor.

How do you calculate amps in a 3 phase circuit?

The formula to find amps for a three phase AC circuit is a little different than the formula for a single phase circuit: amps = (kW × 1,000) ÷ (√3 × PF × volts) For example, find the current of a 25kW three phase generator with an efficiency of 80\% at 240 volts. amps = (kW × 1,000) ÷ (√3 × PF × volts)
