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 should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW induction motor
How to build a Rotary phase converter?
A simple Rotary phase converter is just a motor generator set. An electric motor running on the input voltage/current/phase/frequency. it drives a generator that supplies a different voltage/current/phase/frequency. So an electric motor and an electric generator connected together mechanically, either on the same shaft, or via gears, constitutes a Rotary phase converter. the above is incorrect, the motor/generator is the same motor, just one 3 phase motor is needed, it will run on T1 and T2, and put out L1, L2, and L3. You just need to know how to wire it up and what to do to get it to spin over on simple single phase 220, it will create three phase 220.
What is the connection of normal wire star or delta?
normally delta connection wired in 3 phase induction motor. during starting wiring is in Star and after running normal speed changeover to delta .beacause starting time its phase voltage equals less root3 times of line voltage ,line current and phase current equals. in Delta phase voltage and line voltage equals, and phase current equals root3 times line current
Should a starting windings in the split phase motor fail to energise what would be the result?
what will be the result if the starting winding in a split phase motor fails
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 should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW induction motor
Why you use three phase electricity?
Three phase is used mostly with electric motors! Greater power with less current and more economical also. Motor runs cooler and starts quickly with improved starting torque.

Why is a capacitor NOT used in a single phase motor?
Very often a capacitor IS used in a single-phase motor. It provides a phase-shifted current to the starting winding to ensure that the motor runs in the right direction, e.g. clockwise if that is the requirement.
How many current needed for the starting of a 5 horse power single phase motor?
120 volt
Do you measure amps on 220 volt electric motor by measuring one line or both and combining total of the two?
In a single phase 220 volt electric motor just measure one line. That already represents your line current. That line current is equal to your total current circulating in your motor.
What is Ratio between starting and running current of 3 phase ac motor?
The start up current should be listed on the motor nameplate as FLA , full load amps.
Is 380 volts electric motor a single phase or 3 Phase?
It is probably a three phase 50 Hz motor.
Why do ionic crystals cunduct electric current in the liquid phase or when desolved in water but do not conduct electric current in the solid phase?
Magnetricity.
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.
Why are no starting components needed on three-phase motors?
Yes, by using a DOL Starter, which gives a controlled "soft-start" for the motor even though it is always connected in delta configuration.In this type of starting a 3-phase motor, full voltage is applied to the motor through relays and contactors. Its is the most common type of 3-phase motor starter used.DOL means Direct On-Line starter.
