What should be the no load current of an induction motor?
No load current at delta connection = 0.3 x Motor Full load current. If you connect the motor at star connection means, the applied voltage will be reduced, hence as the voltage is proportional to the speed of the motor. The motor will run at 60% of the full speed.
What is the full load current of a 5 hp motor?
Full-Load Current in Amperes Single-Phase Alternating Current Motors HP 115V 230V 5 56 28 7- 1 /2 80 40 10 100 50 The voltages listed are rated motor voltages. The listed currents are for system voltage ranges of 110 to 120 and 220 to 240.
What is meant by no load and full load current?
Essentially, a load receives power from a circuit while a source delivers power to a circuit. So a zero load receives zero power while a full load receives full power (whatever that is in a particular context). Since either an open circuit or short circuit receives zero power, neither of these is a full load.
How many kW is a 5hp motor?

How many kW is a 10 hp motor?
Horsepower (metric) to Kilowatt Conversion Table Horsepower (metric) Kilowatt [kW] 2 horsepower (metric) 1.4709975 kW 3 horsepower (metric) 2.20649625 kW 5 horsepower (metric) 3.67749375 kW 10 horsepower (metric) 7.3549875 kW.
What is load current in motor?
The maximum load current is the maximum continuous current that can be used to continuously drive a load, If the current is higher than that, the motor will run too hot and the insulation will fail eventually. Exceeding the maximum load current slightly will reduce the lifetime of the motor slightly.
What is no load test of induction motor?
The no-load test approximates the stator circuit (Rs and Xs1) and magnetization branch parameters(Xm) of an induction machine. The machine is brought to its rated speed by applying rated three phase volt- age at the stator (Vnl). Corresponding no-load current (Inl) and no-load real power input(Pnl) are recorded.
What is no load in induction motor?
The no-load test of an induction motor is similar to the open-circuit test of a transformer. The motor is not connected from its load, and the rated voltage at the rated frequency is applied to the stator to run the motor without a load. The 2-wattmeter method measures the input power of the system.
How many amps is a 40 hp motor?
AC Motor Full Load Amperes HP 200 Volts 550-600 Volts 25 78.2 27 30 92 32 40 120 41 50 150 52.
How many watts are in a horsepower?
Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts and the metric horsepower, which is approximately 735.5 watts.
How many amps are in a kW?
4.55 Amps Power (kW) Voltage (220 V) Amperage (A) 1 kW to Amps: 220 V 4.55 Amps 2 kW to Amps: 220 V 9.09 Amps 4 kW to Amps: 220 V 18.18 Amps 6 kW to Amps: 220 V 27.27 Amps.
What is the full load current?
A full load current is the largest current that a motor or other device is designed to carry under particular conditions. The starters shall be suitably rated to continuously carry the full load current of the motor and also accept the starting current surges without tripping.
What is a current load?
Load current in this context is simply the current thru the wire. As you say, a load consumes power. That power is delivered electrically, which means it is the product of voltage and current. The load current is just that current.
How do you calculate full load current?
I= P/(1.732*V*Cos pi) Here three-phase full load current is equal to the power divided by 1.732 times of line to line voltage and power factor.
How many HP is a 30 kW motor?
30 kW Motor (40 HP) 415 V Three Phase Cast Iron Motor – TechTop.
How many kW is a 1 hp motor?
1 horsepower is equal to 0.74569987 kilowatts, which is the conversion factor from horsepowers to kilowatts.
How many kW is a kWh?
1 kWh equals one hour of electricity usage at a rate of 1 kW, and thus the 2 kW appliance would consume 2 kWh in one hour, or 1 kWh in half an hour. The equation is simply kW x time = kWh.
Which is greater HP or kW?
To convert kilowatts to horsepower, we multiply the number of kilowatts by 1.34. The result is that 80 kilowatts is roughly equivalent to 107 horsepower.
How many kW is a 50 hp motor?
So — 37,300 Watts / 0.92 = ~ 40,500 Watts is required to be input to the motor to get the 50 HP output. In terms of kiloWatts (kW), — the terms that your electric company charges you — this is approximately 40.5 kW.
Is kW the same as HP?
Kilowatt to horsepower conversion is one of the most common ones. We’ll convert kW to HP for 3 examples further on: For an average 110 kW gas car (Example 1) 48,000 BTU 5-zone mini-split air conditioner (Example 2)kW to HP Table. Kilowatts (kW) Horsepower (HP) 500 kW to HP: 670.51 HP.
What is normal load current?
Normal, or load, current may be defined as the current specifically designed to be drawn by a load under normal, operating conditions. Depending upon the nature of the load, the value of normal current may vary from a low level to a full-load level.
Why motor starting current is high?
This high current in the rotor will create its own magnetic field which opposes the main stator magnetic field, this weakens the stator magnetic field so the back EMF in the stator will drop and the supply voltage will be much higher than the stator back EMF and so the supply current increases to a high value.
What is rated power of motor?
Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor’s efficiency tends to decrease dramatically below about 50% load.
