What is the length of time that a motor can safely run on starting and full load current?

It depends on the insulation provided in winding, motor can safely run on full load current. and over that it may burn but depends on cooling system of the motor. Motor can burn if insulation fails, failure of insulation depends on only the temperature rise.

How do you calculate voltage drop for starting motor current and how to get the starting pf?
How do you calculate voltage drop for starting motor current
Which motor has a higher starting torque?
A series-wound commutator motor has the best starting torque because the torque is proportional to the square of the current, and the starting current is set by a current-limiting resistor which is switched out as the motor builds up speed.
What is the starting current of 320 KW motor?
depending on kva class of the motor between 4-8 times the running current
What will be the starting current of a 335hp Sqcage motor on no load?
Across the line starting of a motor can be as high as 300% of the full load amps.
A particular 3 phase induction motor has a LRA of 100 amps What is its approximate starting current?
LRA (locked rotor amperage) is not considered. Starting current for a motor is usually in the neighbourhood of 300% of the FLA (full load amps). The FLA is taken from the motor's nameplate.
How do you calculate voltage drop for starting motor current and how to get the starting pf?
How do you calculate voltage drop for starting motor current
How many percent will be the starting current for motor?
Motor starting current is typically 5-7 times the rated current of the motor. (For three phase induction motors)
What is the ac motor starting current?
what is the starting current of 2ton window ac voltas
Why is the starting current high in DC motor?
The starting current is high because when the motor is not rotating no back-emf is generated, leaving the starting current to be determined by the armature resistance, which should be low.
Which motor has a higher starting torque?
A series-wound commutator motor has the best starting torque because the torque is proportional to the square of the current, and the starting current is set by a current-limiting resistor which is switched out as the motor builds up speed.
Starting current of 160 kw motor with star delta starting?
Assuming the Motor is IE1 Efficiency and 4 Poles, the in rush current will be 1183 A
Why you use DOL starter in starting of motor?
because of starting current of induction motor is very high and it damages the insulation of motor
How is the full load current different to the starting current- is the full load current higher or lower than the starting current?
While starting a motor from standstill to its rated speed, the motor has to overcome the inertia and generate enough torque to over come it. In the process the motor takes higher current during the starting. Once started and set in motion the current reduces ti its normal value. Full load current is lower than the starting current normally.
What is the Full load motor current of a 75KW motor?
Full load starting current is typically in the region of 5or 6 times the full load motor current;.

What is the starting current of 320 KW motor?
depending on kva class of the motor between 4-8 times the running current
What will be the starting current of a 335hp Sqcage motor on no load?
Across the line starting of a motor can be as high as 300% of the full load amps.
