Is there a different formula for generator and motor effects? What are they?
Different formula for generator and motor ?
Click For Summary
SUMMARY
The discussion clarifies that the formulas for generators and motors are fundamentally the same, differing primarily in their sign conventions. The generator convention indicates that when current and voltage rise in the same direction, the element acts as a generator, producing power. Conversely, under the motor convention, a positive voltage-current (VI) product signifies that the element consumes power. This distinction is crucial for understanding polarity conventions in electrical engineering.
PREREQUISITES- Understanding of electrical engineering principles
- Familiarity with voltage-current relationships
- Knowledge of generator and motor conventions
- Basic grasp of circuit analysis
- Research the RH generator rule and LH motor rule in detail
- Explore the implications of polarity conventions in circuit design
- Learn about power sourcing vs. power consuming elements in circuits
- Study the applications of generator and motor principles in real-world scenarios
Electrical engineering students, circuit designers, and professionals involved in power generation and motor control will benefit from this discussion.

Couldn't you find the formulae on Wikipedia?
They are, essentially, the same formula - or at least the same relationship. The main difference is the sign. RH generator rule - (generighter) and LH motor rule (motors drive on the left, in the UK).

I wonder if omgange is doing electrical engineering?
In EE the terms refer to polarity conventions.
If the current and voltage rise in the same direction across circuit element E, as on the left in the attached sketch, the circuit is said to be using the generator convention.
A positive VI product means that the element is sourcing or producing power and is thus acting as a generator.
If we adopt the motor convention then the current is assumed in the opposite direction to the voltage.
A positive VI product here means the element is consuming power.
