A 4 point starter protects the armature of a dc shunt motor or compound wound dc motor against the initially high starting current of the dc motor. Over compound dc generator is used to reimburse the voltage drop within feeders.

Dc compound motor diagram. Compound dc motor when comparing the advantages of the series and shunt motors the series motor has greater torque capabilities while the shunt motor has more constant and controllable speed over various loads. The self excited motors are further classified as shunt wound or shunt motor series wound or series motor and compound wound or compound motor. A compound dc motor connects the armature and fields windings in a shunt and a series combination to give it characteristics of both a shunt and a series dc motor. This motor is used when both a high starting torque and good speed regulation is needed. A compound wound dc motor also known as a dc compound motor is a type of self excited motor and is made up of both series the field coils s 1 s 2 and shunt field coils f 1 f 2 connected to the armature winding as shown in the figure below. Level compound dc generator is used to provide a power supply for hostels lodges offices etc.
Dc compound motor or compound wound dc motor is also a self excited motor but it is a compound of both series and shunt field coils connected to the armature winding a series field winding connected in series with the armature and a shunt field winding connected in parallel to the armature. Types of dc motor a direct current motor dc is named according to the connection of the field winding with the armaturemainly there are two types of dc motors. It generally converts electrical energy into mechanical energy. These two desirable charac teristics can be found in the same motor by placing both a series. A brushed dc electric motor is an internally commutated electric motor designed to be run from a direct current power source. A dc motor is a device that works on the principle of faradays law of electromagnetic induction.
Compound dc generator is used to provide the power supply for dc welding machines. Briefly we can say that dc compound motor is a combination of. The 4 point starter has a lot of constructional and functional similarity to a 3 point starter but this special device has an additional point and coil in its construction as the name suggests. First one is separately excited dc motor and self excited dc motor. Basics of dc motor. From the above information finally we can.
This article discusses an overview of the series motor and the main function of this motor is to convert electrical energy to mechanical energy. Working principle of 4 point starter. The working principle of this motor mainly depends on electromagnetic law. Thus this is all about the dc generator. The motor can be connected in two arrangements. Brushed motors were the first commercially important application of electric power to driving mechanical energy and dc distribution systems were used for more than 100 years to operate motors in commercial and industrial buildings.
Similarly self excited motors classified into three types namely dc series motor dc shunt motor and dc compound motor. In this article we shall discuss the basics of dc motor and characteristics of different self excited motors like dc shunt series and compound motor.
