The motor's manufacturer is the one who decides how much overloading can be done to their product. As different motors are wound for different applications the motor's engineering department decides what the specifications of each motor type should be. The most common service factor is 1.15. On the motor's nameplate it will be shown as SF 1.15.

What is the difference between Full load Amps and Service Factor Amps on an electric motor?
Full load amps is the amperage at which the motor was designed to work at to achieve its rated horsepower. Service factor amps is the amount of a periodic overload at which a motor can operate without overload or damage. Continuous operation within the service factor amps will shorten the insulation and motor bearing life of the motor as the motor will be operating at a higher temperature than it was designed to.
By how many amps may a three phase motor exceed its data plate rating?
On a normal three phase motor on the nameplate there is a value in the S.F. box. This is the service factor. Depending on the size of the motor this value will vary. Smaller size motors usually have a service factor of 1.15.See related links below.
What is the maximum amp for motor 5.5 kw 4 pole 3ph?
power , P=1.732*V*I*power factor so, the formula for calculate the load current for a 3 phase motor is,I=P/(1.732*V*power factor)
How do you calculate hp from amps?
1 HP is 746 watts in principle. The power is in watts, and the power is the volts times the amps. For an AC motor the power is the volts times the amps times the power factor times a factor that depends on the power-conversion efficiency of the motor.
How do you calculate motor wattage from its resistance?
All you can do is get in the ballpark knowing resistance of windings and the supply voltage. Current = Voltage divided by resistance. Wattage = voltage x current x power factor. For a motor the power factor is between zero and sone number less than one, with one being just a resistive load. So if you calculate the current and use a PF = 1 you can get worse case wattage.
How do you calculate gearbox service factor?
Service factor is gearbox horsepower rating over motor horsepower.

What is the service factor of motor?
service factor of motor is 1.00 or 1.15 . almost all electric motors rated at 1.5 horsepower or more have a service factor of 1.15 or greater. a motor with a 1.00 service factor is usually a very small motor like an exhaust fan in residential bathroom. if a motor has 1.00 service factor all that means is that it can only operate at 100% of its rated amperage. a motor with a 1.15 service factor can periodically be run at 115% of its rated amperage without damaging the motor.

How do you calculate Service factor of a call center?
A method of evaluating a design for a call center system. A particular system is put into use and data collected to quantify various quality of service factors. Each quality of service factor is multiplied times an expense multiplier and added to an agent cost factor. The result is a metric that describes the system in monetary terms. I am not sure but this will be more effective for calculate services factor.... Please visit our website www.inso.us
