Starters for the dc shunt wound and compound wound motors. Compound dc motors comprise an armature winding on the rotor and two field windings on the stator with one that is parallel connected and another that is. A direct current is named according to the connection of the field winding with the armature. This article describes the construction of dc motor. When the direction of shunt field flux and series field flux is the same that means flux of one. Compound wound generators are of two types, known as cumulative wound and differential wound generators. Types of dc motor a direct current motor, dc is named according to the connection of the field winding with the armature. In cumulative wound generators the series field assists the shunt field, whereas, in differential wound generators, series field opposes the shunt field. The selfexcited motors are further classified as shunt wound or shunt motor, series wound or series motor and compound wound or compound motor. There is no difference in the construction of dc motor and generator.
A compound wound dc motor also known as a dc compound motor is a type of selfexcited 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. Briefly, we can say that dc compound motor is a combination of both a shunt wound dc motor and series wound dc motor which means that compound motor has the advantage of high starting torque and efficient speed regulation so it can be used in industrial applications include. Compound wound dc motor or dc compound motor electrical4u. Speed control of dc cumulativecompound wound motor. There are 3 main types of dc motor that are available. Pdf on may 3, 2019, ahmed m t ibraheem alnaib and others published dc motors find, read and cite all the research you need on researchgate. A dc motor may have both field windings wound on the same pole. Manual on loading and unloading power, brake automatic. Pdf new life for old compound dc motors in industrial applications. A compound wound motor has both a series and a shunt field winding, i. Like dc generators, there are different types of dc motors characterized by the connections of the field winding in relation to the armature. A characteristic of series motors is the motor develops a large amount of starting torque. First, one is separately excited dc motor and selfexcited dc motor. In a series dc motor the field is connected in series with the armature.
