What are components of a DC motor starter that can be affected by a high starting current if it is not limited?
armature
When starting a motor car a current of 80 Amps is drawn from the 12 volt car battery. How much Power is dissipated in the starter motor?
12ooo
What is the most suitable method of starting a 10hp motor with reduced inrush starting current?
The most suitable method for starting a 10hp motor with reduced inrush starting current is using a soft starter. A soft starter gradually increases the voltage supplied to the motor, allowing it to ramp up to full speed smoothly, thereby minimizing the initial surge of current. This method helps reduce mechanical stress on the motor and connected equipment, improving reliability and longevity. Additionally, it can enhance energy efficiency during startup.
FCMA starter principle and working during starting induction motor?
The FCMA (Field Control Motor Arrangement) starter principle involves controlling the field current to manage the starting torque and speed of an induction motor. During startup, the motor is initially supplied with reduced voltage to limit the inrush current, and the field current is adjusted to ensure smooth acceleration. As the motor approaches its rated speed, the field current is gradually increased to optimize performance. This method enhances efficiency and prolongs the motor's lifespan by preventing mechanical and electrical stress during startup.
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
Why using on motor star delta starter?
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!
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
What are components of a DC motor starter that can be affected by a high starting current if it is not limited?
armature
What is a disadvantages DOL or direct online starter?
it can not be use for heavy duty motors as well as it requires a high starting current.
Why are the wires to a starter motor very large?
The wires to a starter motor are very large to accommodate the high current required to start the engine. During cranking, the starter motor can draw a significant amount of current, often exceeding 100 amps. Larger wires reduce the resistance and minimize voltage drop, ensuring that sufficient power reaches the motor for effective starting. Additionally, thicker wires help prevent overheating and potential damage during the high-current draw.

What is a three point starter?
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.

Which motor is used for starting engine?
Er... a Starter Motor?
Why Need for starter?
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.

What is the function of liquid in liquid resistance starter?
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.
