How do you calculate armature current in a shunt generator?
To calculate the armature current in a shunt generator, you first need to determine the load current (I_load) and the shunt field current (I_shunt). The armature current (I_a) can then be calculated using the formula: ( I_a = I_{load} + I_{shunt} ). The shunt field current can be found using the field resistance and the terminal voltage. Once you have both currents, simply add them to find the total armature current.
Draw a schematic diagram of a 3 point starter showing various components internal connections and out going leads connected to a dc shunt motor?
A schematic diagram of a 3-point starter for a DC shunt motor includes a few key components: a starter handle, a series coil (or relay), and a shunt motor connection. The starter handle is connected to the series coil, which is in turn connected to the armature winding of the motor. The outgoing leads connect the motor's armature to the power supply, while the shunt field winding is connected to the power supply directly. The starter allows for a gradual increase in voltage and current to the motor, protecting it from inrush current during startup.
What are the factors that influence the speed of the direct-current shunt motor with increasing load?
.The magnitude of the voltage and current of both the armature and shunt field coil. To decrease the speed when the load is increasing then increase the shunt field current while decreasing the armature voltage or current. To increase the speed while the load is increasing then increase the armature current while decreasing the shunt field current. The decreasing and increasing of these currents and voltages can be done by connecting a variable resistor in series or parallel with each of the armature and/or shunt field coil.

What is armature current?
Armature current is the current flowing in a motor's armature. The "armature" is another name for the coil (or coils) of wire which are on the motor's "rotor", which is the part that rotates inside its stator. (The "stator" is the fixed, non-rotating part of the motor.)
What device has a coil armature and heaters?
A motor starter.
Explain the necessity for the use of a starter with a dc motor?
In its simplest form, the starter of a dc motor is a variable resistance in series with the armature circuit of dc motor to reduce the high starting current so that the armature winding does not get overheated and burnt while the motor isgetting started. As the rotating armature of dc motor picks up speed, the starter resistance is gradually reduced so that the motor is able to attain its full speed when the starter is not expected to offer any additional resistance in series with the armature winding of the dc motor. At full speed the motor starts running normally, of course, without the help of starter. In other words, the starter offers resistance to armature current during starting of dc motor only. Under normal working condition of dc motor , the starter is electrically out of armature circuit of the motor. The starter protects the armature of dc motor from getting damaged. The electromotive force (emf) induced in the armature winding during starting builds up from zero value to max value to restrict the armature current within the permissible value at full speed. As the speed of armature/motor build up, armature induced emf also starts building thus reducing the role resistance offered by the starter, hence requiring it to gradually reduce as the motor picks up full speed.
What is shunt current and a armature current?
The terms 'shunt' and 'armature' apply to a particular type of d.c. motor, in which the field windings are connected in parallel with the armature windings. 'Shunt' is an archaic term for 'parallel', so the term 'shunt', in this context, means that the field winding is connected in parallel with the armature winding. The terms 'shunt current' and 'armature current', then describe the currents flowing in the shunt winding and armature winding, respectively.
What is the difference between armature reaction and armature reactance?
armature reactant means loss in armature associated with inductive properties of the coil, while armature reaction include losses due to magnetizing component of current flowing through armature.
Why a DC motor starter is called 3 point starter?
Because it has three terminals L , F and A L - Line (connected to Supply) F - Field (connected to field of dc motor) A - Armature (connected to armature of DC motor) that's y it is called 3 point starter :)

Want to know about two point starter?
In DC series motor, field and armature are in series. so we use only two points. They are line and armature. therefore we use two point starter.
How do you calculate armature current in a shunt generator?
To calculate the armature current in a shunt generator, you first need to determine the load current (I_load) and the shunt field current (I_shunt). The armature current (I_a) can then be calculated using the formula: ( I_a = I_{load} + I_{shunt} ). The shunt field current can be found using the field resistance and the terminal voltage. Once you have both currents, simply add them to find the total armature current.
What is a dead spot on a starter for 1986 Chevrolet camaro?
a spot on the armature that is worn to the point of starter not functioning. a replacement re manufactured starter is in order.
