what is sf on a motor?
316434
Motor Service Factor (SF) is the percentage of overloading the motor can handle for short periods when operating normally within the correct voltage tolerances. ... This means that a 10-hp motor with a 1.15 SF could provide 11.5 hp when required for short-term use.

What is the Difference Between SERVO Drives & VFDs? A VFD (variable frequency drive) is generally used to control a squirrel cage type motor, where both stator and rotor are of a wound type to create the magnetic flux. Servo drives are used to control permanent magnet motors.

STFT = Short term fuel trim, is adjusted by the pcm to overcome small problems that may arise and usually keeps the engine running as close to stoic as possible, if it stays high the pcm will kick in LTFT to try and compensate and when that fails you get a check engine light and either a rich or lean code.

Thus, the rule of thumb for sizing the single phase input on a three-phase drive is to use a VFD rated for 2 times the FLA of the motor. For example if your motor is a 10 HP motor with a FLA of 28 amps, then you would need to select a VFD with an amp rating of 56 amps which ends up being around 20 HP.

Full-Load-Amperage (FLA) refers to the motor's rated-current at rated-load and rated-voltage. This is the amount of current (amps) the motor will draw from the electrical system when producing its rated output horsepower. This value can also sometimes be referred to as: Running Amps, Rated Amps, or just AMPS.

The motor can be safely operated up to 120 % of its base speed. A 1440 RPM motor can be operated up to 1728 RPM by increasing frequency up to 60 Hz. The VFD allows increasing frequency up to 100 Hz or so, but other limiting factors of the motor must be checked.

Shaft currents induced by VFDs can lead to motor failures. Without some form of mitigation, shaft currents travel to ground through bearings, causing pitting, fusion craters, fluting, excessive bearing noise, eventual bearing failure, and subsequent motor failure. This is not a small problem.

In a sense a GDI engine is like a DI diesel engine but with a suitably-positioned spark plug and a gasoline fuel, instead of the easily auto-igniting diesel fuel, in-cylinder injection system. In practice, some degree of throttle control is usually required for GDI engines, compromising the SFC improvement potential.
