Which motor has this characteristics curve
Answers
Answer:
To each Torque value corresponds a value of current and speed. Every point, corresponding to a specific load is located on an ideal, vertical line starting from the torque value on the “x” axis.
In the chart is then defined an area called “continuous working area” which encloses all the working condition up to the line defining the nominal values.
The nominal working load is the last one, in ascending order of applied load, to which the motor can work continuously without being damaged.
The nominal values written in the technical data sheets are indicative values and to homologate a product it’s necessary to run a life test.
About the life of a Dc motor or a DC gear motor, there are no parameter to define with precision how long can run a motor under a specific load and with a certain duty cycle.
Every application has in fact their peculiarities, like mechanical friction, peaking, special environmental conditions, which can condition also strongly the brushes life.
