What are the applications of different types of DC motor?

What are the applications of different types of DC motor?

The shunt motors are used where constant speed is required and starting conditions are not severe. The various applications of DC shunt motor are in Lathe Machines, Centrifugal Pumps, Fans, Blowers, Conveyors, Lifts, Weaving Machine, Spinning machines, etc.

What are the different types of DC motors?

There are 4 main types of DC motors:

• Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux.
• Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current.
• Shunt DC Motors.
• Compound DC Motors.

What are types of DC motor and explain?

Mainly there are two types of DC Motors. One is Separately Excited DC Motor and other is Self-excited DC Motor. The self-excited motors are further classified as Shunt wound or shunt motor, Series wound or series motor and Compound wound or compound motor. The dc motor converts electrical power into mechanical power.

What are the different types of DC motor explain with diagram?

If the shunt field winding is only parallel to the armature winding and not the series field winding then its known as short shunt DC motor or more specifically short shunt type compound wound DC motor. The circuit diagram of a short shunt DC motor is shown in the diagram below.

What are the characteristics of dc motor?

Generally, three characteristic curves are considered important for DC motors which are, (i) Torque vs. armature current, (ii) Speed vs. armature current and (iii) Speed vs. torque.

What is the working principle of DC motor?

The basic working principle of the DC motor is that whenever a current carrying conductor places in the magnetic field, it experiences a mechanical force. Fleming’s left-hand rule and its magnitude decide the direction of this force.

What are the main parts of DC motor?

These components are: a stator, a rotor, a yoke, poles, armature windings, field windings, commutator, and brushes. Many of its parts are the same as parts of AC motor, but with a little change.

Where are DC motors used?

At home, small DC motors are used in tools, toys and various household appliances. In retail, the applications of DC motors include conveyors and turntables, while in an industrial setting, large DC motor uses also include braking and reversing applications.

What are the types of starters?

Types of Magnetic Motor Starters

• Direct-On-Line Starter. The direct-on-line starter is the simplest form of motor starter, other than a manual starter.
• Rotor Resistance Starter.
• Stator Resistance Starter.
• Auto Transformer Starter.
• Star Delta Starter.

In general, DC motors are used as variable speed drives and for the applications in which sever, torque variations occur. Now that you’re familiar with different DC motor types let’s get through their usages and applications. Series DC motors are generally used where high starting torque is required, and speed variations are possible.

What are the characteristics of a DC compound motor?

Torque and Speed of this Differential compound wound motors are almost constant. This motor also got the tendency toward speed instability with a possible motor running away. DC compound motors are much suitable for places where need higher starting torque on the constant speed. The applications of DC Compound motors are as following.

How is a self excited DC motor classified?

In case of self excited DC motor, the field winding is connected either in series or in parallel or partly in series, partly in parallel to the armature winding. Based on this, self excited DC Motors can be classified as:

What kind of magnets are used in DC motor?

The construction of these types of DC motor are such that, radially magnetized permanent magnets are mounted on the inner periphery of the stator core to produce the field flux. The rotor on the other hand has a conventional DC armature with commutator segments and brushes.
