Neat Dc Compound Motor Diagram
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 s1 s2 and shunt field coils f1 f2 connected to the armature winding as shown in the figure below.
Dc compound motor diagram. Speed is controlled by variable resistors in the shunt field and armature circuit. The working principle of this motor mainly depends on electromagnetic law which states that whenever a magnetic field is formed. Fig speed control of a compound motor long shunt type.
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. Dc motor is a device that uses dc power for the creation of mechanical power there are numerous types of dc motor such as shunt dc motor series dc motor compound dc motor. The motor can be connected in two arrangements.
Series field winding and shunt field winding gave this motor the name of compound dc motor. The compound motor is further subdivided as cumulative compound motor and differential compound motor. The armature is perpendicular to the axis of the cylinder.
Presence of both the field windings i e. This motor is used when both a high starting torque and good speed regulation is needed. In a cumulative compound motor the flux produced by both the windings is in the same direction i e.
Dc motors are found in many special industrial environments motors drive many types of loads from fans and pumps to presses and conveyors many loads have a definite torque speed characteristic other loads have a highly variable torque speed characteristics motors must be adapted to the type of loads to be driven motor types shunt series and compound connections. The connection diagram of the compound motor is shown below. A dc motor having both shunt and series field windings is called a compound motor.
Cumulative compound motors connect the series field to aid the. Hi readers welcome to the new post. Dc motor diagram different parts of a dc motor.
