# What is series wound DC motor?

## What is series wound DC motor?

A series wound DC motor like in the case of shunt wound DC motor or compound wound DC motor falls under the category of self-excited DC motors, and it gets its name from the fact that the field winding in this case is connected internally in series to the armature winding.

How does a series wound motor work?

A series DC motor converts electric energy to mechanic energy based on the electromagnetic principle. In this type of DC motor, a power supply terminal sits at one end of the armature and field coils. By applying the voltage, power starts in these terminals and passes through armature and field windings.

### What does a series wound DC motor produce?

Series wound DC motors And for series wound motors, torque is proportional to the square of current, so these motors are able to produce very high torque, especially at startup. Series wound DC motors are best for applications that require high startup torque, without the need for speed regulation.

What is the principal advantage of the series wound DC motor?

What is the principal advantage of the series-wound dc motor? High starting torque.

#### What is a series wound generator?

series-wound in Electrical Engineering The series-wound generator is used principally to supply a constant current at variable voltage. If a motor or generator is series-wound, it has the field and armature circuits connected in series.

What is DC series?

Definition: A DC series motor is a machine that is used at a place where high torque operating conditions are required. It is a machine whose winding is associated in series with the armature winding of the motor.

## Do series wound motors have brushes?

Brush Life These motors use mechanical commutation to connect the power supply to the armature windings; as a result, the carbon brushes which are the connecting points for this commutation will eventually wear down, and must be replaced periodically.

Why the series wound DC motor type has a higher starting torque?

Series wound The field windings are thicker diameter, with fewer turns than in a DC shunt motor, so the resistance of the windings is lower. This allows the series motor to draw a large amount of current and produce a high amount of torque.

### What is the advantage of a series wound motor?

Advantages of DC series motors: Protection is very easy. It is cost-effective. Series wound motors can use for AC or DC supply so it is also known as universal motors. Compare with shunt motor DC series motor develop power for the same construction size.

How does a series wound DC generator work?

A series-wound generator uses very low resistance field coils, which consist of a few turns of large diameter wire. The voltage output increases as the load circuit start drawing more current. Under low-load current conditions, the current that flows in the load and through the generator is small.

#### What is a series wound DC motor?

A series wound DC motor like in the case of shunt wound DC motor or compound wound DC motor falls under the category of self-excited DC motors, and it gets its name from the fact that the field winding in this case is connected internally in series to the armature winding.

What are the interesting facts about the DC series motor?

Another interesting fact about the DC series motor worth noting is that, the field flux like in the case of any other DC motor is proportional to field current. But since here i.e. the field flux is proportional to the entire armature current or the total supply current.

## What is the difference between back EMF motor and shunt wound motor?

Back e.m.f. in a d.c. motor regulates the flow of armature current i.e., it automatically changes the armature current to meet the load requirement. In shunt wound motor the field winding is connected in parallel with armature . The current through the shunt field winding is not the same as the armature current.

What is speed and torque of series DC motor?

Speed and Torque of Series DC Motor. A series wound motors has linear relationship existing between the field current and the amount of torque produced. i.e. torque is directly proportional to current over the entire range of the graph.
