SUMMARY

In the context of motors, "full load" refers to the maximum rated load that causes the motor's armature to draw its full rated current. Conversely, "no load" indicates the condition when the motor operates without any mechanical load attached to its shaft, resulting in minimal current draw. Understanding these terms is crucial for evaluating motor performance and efficiency in various applications.

PREREQUISITES

Basic understanding of electrical engineering principles
Familiarity with motor operation and characteristics
Knowledge of current measurement in electrical circuits
Understanding of mechanical load concepts

NEXT STEPS

Research "motor efficiency calculations" to understand performance metrics
Explore "current draw measurements" for different motor loads
Learn about "torque-speed characteristics" of electric motors
Investigate "motor control techniques" for optimizing load management

USEFUL FOR

Electrical engineers, motor technicians, and anyone involved in motor design and performance analysis will benefit from this discussion.

What is the meaning of full load and no load, in the context of motor? Does the load here mean mechanical load?

In that sense, is it that no-load current means the current in motor when the mechanical load is absent?

yes, it means that there is no load attached to the motor shaft

and full load means full rated load

i think so , the load which causes the armature to draw full rated current

Thread 'uA709 op amp compensation'

Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
