What will happen if induction motor is in star-star connected?
If a motor is connected in a star configuration it will operate at a slower speed. This is the working process that a star delta starter operates on. At first through the starter the motor starts in the star connection. When the motor gets up to its highest speed in that connection it times a timer out , the star starter drops out and the delta starter pulls in and then connects the motor in the delta connection. This allows more voltage to be applied to the motor and it then speeds up to its nameplate rated RPM.
What happens to d.c motor when Field is weakened in DC?
when the field winding of dc motor opens the flux is zero so the speed is inversely propotional to speed ,so motor runs at dangerous speed...........
Why a machine should run with synchronous speed?
A synchronous motor is not self starting.However when it is provided with some prime mover ,which rotates it up to 80% of sync. speed,then it continues to rotate at sync.speed even after prime mover is removed.It happens so because rotor poles are locked with rotating magnetic field and hence the speed is always synchronous.
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.

What is the use of 4 point starter in motors?
in 4 point starter we use a protactive rasistance to control the speed of motar in 3point starter speed is uncontolled
What happens to the speed of light in motor oil?
As long as the light remains in the motor oil, nothing happens to its speed.
How many 2838 Lego motor rotates per minute?
A 2838 Lego motor has a max speed of 4100 rpm.
Where is the speed sensor located on a 1995 golf gti?
speed sensor is behind starter motor
What Is A Reduction Gear Starter Motor?
Its a starter that has a set of gears between the motor and the starter pinion which allows higher-speed, lower-current, lighter and more compact motor assembly while increasing cranking torque.
Why does a cranking motor have an unusually high amperage draw accompanied by a slow cranking speed?
The armature bushings inside the starter motor are probably shot. Time to replace the starter.
How can you change the brightness of the speed of motor?
By introducing a number of resistors regarding the type of your motor and the starter used.By Sir Jembe.
What happens when force is balance?
The body observing the force is either in stationary position or rotates with constant speed.

Can i check compression with motor out of vehicle?
Yes, but only if you can crank engine at normal starter speed.
Why wont my 1985 5 speed fiero start without a pushstart?
Bad starter motor?
What type of motor is used in a starter motor?
None, it is an electric motor In fact, most cars have SERIES connected starter motors - an electric motor where the field windings (the ones that are fitted to the case of the machine and don't move) have the same current flowing in them that the armature (the rotating part of the motor) has. A series motor has very high starting torque, so it's ideal for getting a large lump of scrap metal turning over, but it has poor running (high speed) torque and poor speed control. (Speed control is so poor that if you spin up a starter motor without a load, it may over-speed and possibly throw its windings out of the armature!) Some starter motors use permanent magnets for the field system - these magnets are quite powerful and give the motor good starting torque, and magnet systems are smaller than the series coil systems, and make the starter motor a bit lighter and cheaper. These motors also have a lower top speed at no load, too.
How does a motorcycle starter motor work?
When you hit the starter button the starter relay send power to the starter. the starter solenoid pushes the starter shaft outward and the starter turns. When the solenoid moves the shaft it is connected to the jackshaft which ingages the starter gear on the clutch
