Which of the following is a benefit of shunt DC motor?

direct current machines can use for heavy industrial applications where torque and speed wider range. Shunt wound motor able to runs at a predetermined speed. The power supply of DC motor is any way cheap.

What are the advantages of DC shunt motor?

Advantages of Dc shunt motor:

  • The power supply of the DC motor is any way cheap.
  • Shunt would motor able to runs at a predetermined speed.
  • The speed of a dc shunt motor is sufficiently constant.
  • Direct current machines can use for heavy industrial applications where the torque and speed wider range.

What are the advantages and disadvantages of a shunt motor?

A shunt wound motor runs at a predictable speed and shows relatively little speed change as the load changes. Constant speed operation can be a disadvantage if variable speed is desired. In AC motors, there are usually no brushes which improves the lifetime of the motor.

What are the advantages and disadvantages of DC motor?

DC Motor Advantages & Disadvantages

Advantages Disadvantages
Inexpensive controls for speed regulation Cogging at speeds of less than 300 rpm
Generally a low-cost motor option Significant power loss on full wave rectified voltage
Easily pairs with gear reducers High starting torque can damage reducers

What are the applications of DC shunt generator?

Applications of DC Generators

  • These generators are used to charge batteries, provide lighting and provide excitation to alternators.
  • They are used to provide field excitation current for regenerative braking in DC locomotives.
  • They are used in DC motors where speed control is necessary.

What is the main disadvantage of shunt motor?

As the load changes, a shunt wound motor runs at a predictable speed. If variable speed is desired, constant speed can be a disadvantage. The lifetime of the motor is usually not improved by brushes.

Which motor is more powerful AC or DC?

AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.

What is advantage and disadvantage of induction motor?

Induction motors always operate under lagging power factor and during light load conditions they operate at very worst power factor (0.2 to 0.4 lagging). Some of the disadvantages of poor power are increase in I2R losses in the system, reduction in the efficiency of the system.

What are the main limitations of DC motor?

Disadvantages of DC motors

  • High initial cost.
  • Increased operation and maintenance cost due to the presence of commutator and brush gear.
  • Cannot operate in explosive and hazard conditions due to sparking occur at brush (risk in commutation failure)

Why not use DC current in our homes?

Direct current is not used at home because for the same value of the voltage, DC is more lethal than AC since direct current does not go through zero. Electrolytic corrosion is more an issue with direct current. DC inductors are more complicated. It requires commutators, electronic switches and brushes.
