What device may be wired into the starting circuit of a motor to improve the starting torque?
I assume a 3 phase, AC induction motor. A star delta starter or a soft starter can be used. A soft starter is better compared to a star delta starter, but it is more expensive.
What is a soft starter?
A soft start is a starter that bring a motor from the starting point of a slow speed in to a multiple speed that can be programmed in the starter Imagine you have a big plant in your factory, the voltage will go down/up when the plant start/stop, cause the sharp start/stop The soft starter is controlling AC motor in soft start/stop to eliminate such problems.

In 3 pH Delta motor connection the upstream ACB is tripping due to ground fault protection while motor starts with soft starter why?
Check the earth fault trip off set limit of the ACB. It may be too low.
What is the difference between a star-delta starter and a DOL starter?
At least two types of 3-phase electric motor starter are available: Direct-On-Line (DOL) and Star-Delta.For more information about how they work, and the differences between them, see the answers to the Related Questions shown below.
Which is better inverter or soft starter?
An inverter is just a device to invert one form of electrical power supplied to its input into another form of electrical power as its output. A soft starter may be included into an inverter design, its function is just to provide temporary power to the inverter until it gets started. After that the soft starter is disabled, usually by a diode feedback link.
Soft starter for a dc motor?
It is an advanced power electronic device to start the motor with a very smooth starting curve. It is next generation starter compared to DOL or star Delta starter

Soft starter tripping?
Most of the motors are usually controlled by the soft starters which usually trip frequently. One of the steps in find why the soft starter has tripped is looking at the motor circuit protector rating.

Can you use star delta starter and soft starter in to same motor?
Probably. More importantly, why would you want to? The Star/Delta starting method is used to minimize motor starting current, just like a soft starter. Use one or the other. There's no good reason to use both, it will just make things more complicated.
Why we used starter in motor?
There has to be device or a mechanism to start and stop a motor. hence a starter is needed. There are many different ways to start a motor. Considering AC Motor - It could be DOL, Star-Delta starters, which are age old and conventional. Star Delta starter starter is for higher rating motors, example over 7.5 kw, depending upon type of load. There are more advanced starters like Soft starters and Drives also.

Is DOL starter is sufficient for 10HP 2880 RPM motor?
If the application is high starting torque, then go for star delta or soft starters. If not DOL will do.
Camaro 350 Chevrolet boat looking to replace the starter motor can this be done without removing the motor?
I have a Camero Strada 1990 - 350 chev soft clutch and there is no way the starter can be replaced wijhtout lifting the motor. Not all that hard though if you have a chain block and something strong enough to hold it all up. Paul B - Medowie.
