Construction of a DC machine: Note: A DC generator can be used as a DC motor without any constructional changes and vice versa is also possible. Thus, a DC generator or a DC motor can be broadly termed as a DC machine. These basic constructional details are also valid for the construction of a DC motor.
Series DC motor. In a series DC motor the field is connected in series with the armature.The field is wound with a few turns of large wire because it must carry the full armature current. A characteristic of series motors is the motor develops a large amount of starting torque. However, speed varies widely between no load and full load. Series
9/03/2015· Advantages * The series motor has the highest starting torque for a given power rating. When the motor is overloaded, the speed drops and the torque increases. While delivering high torque during an overload, the series motor draws less current
12/11/2016· DC Series Motor Speed Control methods. In this post, let us discuss about various DC Series Motor Speed Control methods. (a) The speed of a d.c. series-wound motor is given by: where N= Speed of DC series Motor k = Constant V = Terminal voltage R = Combined resistance of the armature and series field and is the flux
The series DC motor is an industry workhorse for both high and low power, fixedandvariable speed electric drives. Applications range from cheap toys to automotive applications. They are inexpensive to manufacture and are used in variable speed household appliances such as sewing machines and power tools.

11/07/2019· Therefore speed of the 3 types of DC motors shunt, series and compound can be controlled by changing the quantities on the right-hand side of the equation above.. Hence the speed can be varied by changing: The terminal voltage of the armature, V.; The external resistance in armature circuit, R a.; The flux per pole, φ.
15/11/2016· For any dc motor,torque is directly proportional to the flux and armature current. In case of series motor the flux produced is directly proportional to the armature current. Hence torque is directly proportional to the square of armature current....
6/11/2019· Application of DC series motor ⇒ DC series motors are used where high starting torque required. These motors are only used where the variation of speed is possible. series motors are not suitable for constant speed applications. ⇒ DC series motor is used in a vacuum cleaner, traction systems, sewing machines, cranes, air compressors etc.
4/08/2016· Advantages of DC Series Motor: The series motor has the highest starting torque for a given power rating. When the motor is overloaded, the speed drops and the torque increases. While delivering high torque during an overload, the series motor draws less current and power from the source compared to a shunt or compound DC 
DC series motor works on the direct current converting electrical energy to mechanical energy. It works on the principle of generation of rotational motion when a conductor placed in magnetic field carries current. The interaction of the generated magnetic field and external magnetic field results in the rotational movement. In this motor field winding is placed in series to the armature.
Characteristics of DC compound motor DC compound motors have both series as well as shunt winding. In a compound motor, if series and shunt windings are connected such that series flux is in direction as that of the shunt flux then the motor is said to be cumulatively compounded.
Types of DC Motor A Direct Current Motor, DC is named according to the connection of the field winding with the armature.Mainly there are two types of DC Motors. First, one is Separately Excited DC Motor and 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.
12/11/2017· Crushing motorcycles and bicycles Machine destroys everything Motorbike crusher: Motorbike crusher is an industrial device used to reduce the
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel,or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled,or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different
17/12/2016· This video will walk you through the connections for a Series DC Motor and will also show how the Series DC Motor runs away without a physical load coupled to the shaft.
Torque equation of Dc motor. Torque equation of dc motor Simply and as Dr. Hugh d Young explains torque is the propensity of force to cause a rotational motion, and here in Dc motor the torque develops between the armature and the stator, and it’s given by the product of the force and the radius at which the force acts.. DC Motor Torque equation: It will be easy if

A DC motor is an electrical machine that converts electrical energy into mechanical energy. The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical force. The direction of the mechanical force is given by Fleming’s Left-hand Rule and its 
In this post, we will look into the characteristics of a DC series motor. A DC series motor is one type of DC motor in which field winding is connected in series with the armature winding. The performance of any motor can be judged from its characteristic curves known as motor characteristics. There are three 
29/12/2015· Therefore, the starting torque of a DC shunt motor is low, meaning that the shaft load must be small at startup. In a DC shunt motor, torque is proportional to armature current (as shown in the torque equation below). In contrast, for a series-wound DC motor, torque increases as the square of armature current.
Characteristic of a DC Series Motor The figure above shows the circuit diagram series motor. In series motor the current flows in the field winding and the armature are same. The armature current will increases whenever the mechanical load of the motor increase. As a result the flux will increase in the series motor when the armature current increases and vice versa.
Applications of DC Machines In the present day world, the electrical energy is generated in bulk in the form of an alternating current. Hence, the use of DC machines, i.e., DC generators and motors are very limited. They are mainly used in supplying
4. DC MOTORS Almost every mechanical movement that we see around us is accomplished by an electric motor. Electric machines are a means of converting energy. Motors take electrical energy and produce mechanical energy. Electric motors are used to power hundreds of devices we use in everyday life. Motors come in various sizes.
Metal crusher/cans mill is a very popular series of crushing, broken products in the present mechanical equipment market. it is adopt the extruding principle with the high power motor to crush the waste material, then separate the final products by the air circle sorting system.
