What is a series motor?
series motor in Electrical Engineering
A series motor is a direct current motor that has two windings that are in series, with the same current flowing through each. … The series motor provides high starting torque and is able to move very large shaft loads when it is first energized.
What are series motors used for?
A series motor is a direct current motor that has two windings that are in series, with the same current flowing through each. Use of series motors is generally limited to cases where a heavy power demand is necessary to bring the machine up to speed, as in the case of certain elevator and hoist installations.
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.
What is the main disadvantage of a series motor?
The series motor has poor speed regulation. When the load speed of the machine increases, the DC shunt motor keeps its constant speed from no load to full load. The dc series motor’s Torque drops sharply when the speed increases.
What are the advantages of DC motors?
Advantages of DC Motors
- Good speed control. DC motors offer highly controllable speed. …
- High torque. …
- Seamless operation. …
- Free from harmonics.
What are applications of DC motor?
In portable applications using battery power, DC motors are a natural choice. DC machines are also used in applications where high starting torque and accurate speed control over a wide range are important. Major applications for DC motors are: elevators, steel mills, rolling mills, locomotives, and excavators.
How much does a DC motor cost?
