What are the characteristics of DC shunt motor?

1.17, four important characteristics of a dc shunt motor, namely, torque, speed, armature current, and efficiency, each plotted against the useful output power, are shown. These curves are also known as performance curves of a motor.

What are the characteristics of a dc series motor?

Characteristics of a DC Series Motors:

  • Speed-Current Characteristic:
  • Since on no load the series motor attains dangerously high speed, which causes heavy centrifugal force resulting in the damage of machine, series motors are not suitable for the services:
  • Torque-Current Characteristic:
  • Speed-Torque Characteristic:

What are the applications of dc shunt motor depending on its characteristics?

DC Shunt Motor Applications

  • These motors are used wherever stable speed is required.
  • This kind of DC motor can be used in Centrifugal Pumps, Lifts, Weaving Machine, Lathe Machines, Blowers, Fans, Conveyors, Spinning machines, etc.

Which type of motor characteristics are similar to dc shunt motor?

Speed-Torque Characteristics :

Similar to the dc shunt motor, the N vs T relation of the dc series motor is similar to N vs Ia (a parabolic curve) as shown in figure (c). At no-load, Ia will be low, and hence torque, thus speed will be very high. As the load increases, torque increases, and speed decreases.

What are DC characteristics?

The fundamental characteristic of a DC signal is the absence of changes in polarity. If you connect a DC voltage signal to a resistor, the resulting current will always flow in the same direction. The magnitude of the current may exhibit large variations, but the direction does not change.

How the characteristics of DC series motor differs from DC shunt motor?

A series motor respond by decreasing its speed with small increase in current for a given load torque. A shunt motor holds its speed nearly constant with large increase in input current for same amount of load torque.

What are the characteristics of DC shunt generator?

Characteristics of DC Shunt Generator

To build up voltage of a shunt generator, the generator is driven at the rated speed by a prime mover. Initial voltage is induced due to residual magnetism in the field poles. The generator builds up its voltage as explained by the O.C.C.

How do you identify a DC shunt motor?

A DC shunt motor (also known as a shunt wound DC motor) is a type of self-excited DC motor where the field windings are shunted to or are connected in parallel to the armature winding of the motor. Since they are connected in parallel, the armature and field windings are exposed to the same supply voltage.
