Electrical Engineering ⇒ Topic : D.c Motor characterstics
The characteristic curves of a motor are those curves which show relation between the following quantities :
Torque and armature current, i.e., Ta/Ia, characteristic.
This is also known as electrical characteristic.
Speed and armature current, i.e., N/Ia, characteristic.
Speed and torque, i.e., N/Ta. characteristic.
This is also known as Mechanical characteristic.
Following relations are worth keeping in mind while discussing motor characteristics.
