What are the different types of DC motors and their characteristics? (different types of DC motors and What are the characteristics of DC motor?)

Hello friends, in this article we will know how many types of DC motor are there? And what are the characteristics of DC motor? And learn about various facts related to it.

The motor in which dC supply is given, that motor is DC. called motor.


DC. Motor (DC motor) is of the following types –

DC. Shunt motor (DC shunt motor) –

IL = Ia + Ish
Ish = V/Rsh
Back emf, Eb = V - IaRa
Power input = VIL
Power developed Pdev = VIL - VIsh - I²aRa

DC. DC series motor

IL = Ise = Ia
Back emf, Eb = V - I(Ra + Rse)
Power input = VIL
Power developed
Pdev = EbI = VI - I²(Ra + Rse)

DC. DC Cumulative Short Shunt Motor

IL = Ia + Ish = Ise

DC Differential Compound Motor

डी.सी. मोटर्स के गर्म तथा शीतल होने से संबंधित समीकरण (Heating and cooling Equations) निम्न हैं -
θ = θm (1 - et/Th)
θ = θi (1 - e-t/Tc)
जहां θm मोटर के गर्म होने के समय अंतिम ताप है तथा θi, सामान्य ताप ( ambient temperature) के ऊपर प्रारम्भिक ताप है।

Th and Te are heating and cooling time constants. t is the time in seconds.

DC Motor characteristics

DC. Motors have the following three main characteristics. ,

Torque – Armature Current (T/I)aTorque – Armature current characteristics of DC motor

This characteristic is the armature current (I) of the motor.a) and the mechanical torque (T) produced in the motor. It is also called the electrical characteristic curve of the motor.

Torque-armature current characteristics of DC motor

Speed ​​– Armature Current (N/I)aSpeed ​​– armature current characteristics of DC motor

From this curve the relation between the armature current of the motor and the speed (rpm) of the motor is found.



Speed-Armature current characteristics of DC motor

Speed ​​– Torque characteristics of DC motor

This characteristic is known with the help of the above characteristics, from this characteristic the relationship between the speed of the motor and the torque is known.
