Where can Motors be found?
Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives. Small motors may be found in electric watches.
Where are AC and DC motors used?
Difference Between AC and DC Motor
|Parameter||AC Motor||DC Motor|
|Applications||AC motors are applicable to the need for high speed and variable torque.||DC motors are applicable to the need for variable speed and high torque.|
|Uses||Mainly used in large industries.||Mainly used in small domestic appliances.|
What items have DC motors?
Good usually Purely battery or battery/mains motorised appliances will usually have DC motors – eg electric toothbrush, razors, battery belnders, … .
What are the 3 types of DC motors?
There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.
How does DC motor differ from DC generator in construction?
The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts mechanical energy into an electrical energy.
What is Series DC motor?
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.
Why are the DC motors preferred for traction applications?
Explanation: DC motors are used for traction as, according to the characteristics of DC motors speed is inversely proportional to torque and square of armature current as well, if linear magnetization is concerned. Thus, DC motors are perfectly suitable for traction.
