For 1 hp motor, a single phase starter is used. Because a single phase starter gives economy consumption,easy trouble shooting and easy installation when compared to three phase starters and supply....
It depends on the voltage, which you did not specify. Please restate the question, giving the voltage.
You also have to add, single phase? or multiple phases?
1hp = 750w @230v
...1500w

Start current depends on load but 8-10x is usual

How do you calculate voltage drop for starting motor current
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.
Large DC motors with field windings instead of permanent magnets present a very heavy load when starting. To prevent fuses blowing, a series of ever smaller resistors are sequentially switched in series with the motor. As the motor picks up speed, a back EMF in opposition to the applied voltage limits the maximum current. When the motor reaches it's running speed the 'starter' is out of circuit.
because at the starting the induction motor drawn a heavy current thats why we use starter to increase the starting resistance of the induction motor!
because of starting current of induction motor is very high and it damages the insulation of motor
armature
it can not be use for heavy duty motors as well as it requires a high starting current.

A three point starter is a device that is meant to help start a DC motor. A three point starter will start device without much starting current.
Er... a Starter Motor?
Starter motor is a required to start (crank) the engine. When you turn ur key it will complete the crkt and the battery current flows thorugh exitation winidng of solenoid of starter. which thern after send this current to the armature that turn the pinion which is now in cotact wiht the ringger (flywheel ) of the engine. And thats hw it rotates the ring gear of the engine giving it the neccessary starting toque.
How do you calculate voltage drop for starting motor current
Combination of water and caustic soda for improving the resistance in starter, that's called Liquid Resistancestarter.If any slip ring Induction motor, at the time of startinggiven the external resistance required to rotor side, why because starting current and starting torque is very high.So we are using resistance starter depend on motor capacity , at that place using Liquid resistance starter.Liquid resistance starter (LRS) ,IN which externalresistance is liquid media which is use for the startingmethod of slip ring motor. For starting of slip ring motor external resistance arerequired so that we use liquid (addition of some causticsoda)as resistance so that is called as LRS.
question is incomplete, I think you ask how much current consumed by this motor. for starting this motor we need a star/delta starter and a three phase supply.
Yes! · To accelerate the motor to the rated speed · To limit the starting current in the armature to a safe value · To disconnect the motor in case of a supply failure or overload
