Series DC motors are a group of self-excited DC motors in which the field coil is connected in series to the armature winding and thus a higher current passes through it. A series DC motor mission is to turn the electrical energy into mechanical one based on electromagnetic law.8 Oct 2020
Where is DC series motor used?
Series DC motors are generally used where high starting torque is required, and speed variations are possible. These types of direct connection motors are, for instance, used in the traction system, cranes, air compressors, vacuum cleaners, sewing machines, etc.16 Oct 2020
What is a DC series generator?
It is a machine that works on the principle of electromagnetic Induction and it converts the mechanical input given to electrical energy. The field winding is attached in series with the armature winding of this type of machine.29 Nov 2019
What is the main function of a DC motor?
A direct current (DC) motor is a type of electric machine that converts electrical energy into mechanical energy. DC motors take electrical power through direct current, and convert this energy into mechanical rotation.
What is the main advantage of a series DC motor?
Advantages of DC Series Motor Dc series motor have good accelerating torque. Dc series motor have a relatively huge starting torques. Dc series motor delivers high torque during an overload. The dc series motor draws less current and power from the source compared to a shunt or compound motor.
What are the applications of series motor?
- Cranes.
- Air compressor.
- Lifts.
- Elevators.
- Winching system.
- Electric traction.
- Hair drier.
- Vacuum cleaner and in speed regulation application.
What is the disadvantage of Series DC motor?
Disadvantages of DC Series Motor Speed regulation in the series motor is quite poor. With the increase in the load speed of the machine decreases. (DC shunt motor maintains almost constant speed from no load to full load). DC series motor should always require to be loaded before starting the motor.20 Oct 2017
What are the advantages and disadvantages of DC motors?
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 is advantage 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.
