What is no load current?
The no-load current is the current required just to turn the motor shaft with nothing connected. It is the current required to overcome the bearing and brush friction plus the aerodynamic drag caused by the rotor moving in the air and moving air through the motor for cooling purposes.
What is the purpose of no load current?
While primary winding carries a small current I0 called no-load current which is 2 to 10% of the rated current. This current is responsible for supplying the iron losses (hysteresis and eddy current losses) in the core and a very small amount of copper losses in the primary winding.
What is full load and no load current?
The terminal voltage when full load current is drawn is called full load voltage (VFL). The no load voltage is the terminal voltage when zero current is drawn from the supply, that is, the open circuit terminal voltage. Some portion of voltage drops down due to internal resistance of voltage source.
What is meant by load current?
The Load Current can be defined as 1) Full load current: the maximum current that an electrical machine can operate; 2) Rated Current: the current rated on the nameplate of an electrical machine; 3) Nominal Current: is generally mentioned in the specification documents that is normally the same value as the rated one; …
What is no load?
A no-load fund is a mutual fund in which shares are sold without a commission or sales charge. A no-load fund is the opposite of a load fund, which charges a commission at the time of the fund’s purchase, at the time of its sale, or as a “level-load” for as long as the investor holds the fund.
How much is no load current?
The motor will take 10% of the full load current. therefore, No load current at star connection = 0.1 x Motor Full load current.
What is no load in electrical?
No load power consumption is the electric power consumed by a battery charger when it is plugged into a wall socket but without the mobile phone or other battery device being connected.
Why no load current is less?
As the air gap between the stator field winding and rotor winding is large, the more magnetizing current is needed to create flux which will cut the rotor conductor. So it is an important reason why Induction Motor draws more No Load Current than a transformer.
How do you calculate no load current?
No load current for DC motor = 0.25 x Motor Full load current.
Is load the same as current?
The term “load” can also mean “the amount of power” or “the amount of current” drawn by the thing that is connected to the output of the circuit.
What is maximum load current?
The maximum load current is the smallest amount of current in amps that must be drawn from a particular output for that output to function.
What is load and no load mutual fund?
Investors can choose to purchase units in no-load or load mutual funds. No-load mutual funds have no or low fees while load funds have a sales charge or commission attached. You can purchase no-load funds directly from the company or through a brokerage firm but load funds are sold through an adviser.
What does no load condition mean?
Answer Wiki. No-load condition: Typically, this measures the engine losses and residual torque at the crankshaft. This is the lower extreme of the engine capability map and fuel injected is the bare minimum for the engine to sustain a given speed without any external load.
How do you calculate full load current?
Full Load current calculation Single phase Motor: P = V X I X Cos pi. V= Voltage +/- 10 % in Volts. I= Full load current in Amps. Cos pi = power factor. KW = output power in Watts……. All are given at the motor’s name plate details. I = / V X cos pi Amps.
What is no load current in a transformer?
Transformer on No Load Condition. When the transformer is operating at no load, the secondary winding is open circuited, which means there is no load on the secondary side of the transformer and, therefore, current in the secondary will be zero, while primary winding carries a small current I 0 called no load current which is 2 to 10%…
What is the formula for full load current?
In a 3 Phase System Full load current calculate Formula I (current)= Power / √3 × Voltage × Power Factor × Efficiency full Load Current (FLC) is a term used for the maximum current a motor of a given horsepower can draw.
