DC Motor APK

This application allows to simulate the DC motor in transient and steady state and to visualize curves and values.
It allows to choose between 4 operating modes:
Ramp start: The armature voltage rises in a ramp
Voltage step: The armature voltage is imposed in step
Fixed shaft: Locked rotor test
Speed drop: Speed Release Test, Motor Not Powered

Thank you for considering a 5-star vote for this app, which will allow its wide dissemination to the community of students and teachers of Electrical Engineering. If you have any concern, please let me know before voting, by email:

I could certainly provide explanations, without getting a vote below 5 stars.

Thank you for encouraging the development of this kind of apps, by contributing through an in-app purchase of the Premium offer.

Summary
The DC Motor App helps students and teachers to study and understand the operation of the Direct Current Motor (DCM) in transient and steady state.
Several events can be applied during the simulation, such as changes in load torque at different times, armature voltage steps, excitation current, as well as resistive parameter variations.
Simulations can be shared and exported to other apps (Gmail, photos, Excel sheets, documents).

Main characteristics:
Simulation of the Direct Current Motor (DCM) in transient and steady state.
Curves of armature current, excitation current, armature voltage, speed, electromagnetic and load torque, power, as a function of time and in steady state
Different operating modes
Change motor parameters and save them in local files
Apply several load torque events, armature voltage... in the simulation
Simulation parameters (final time, step time...)
Displays the curves by splitting the window into 2 graphs, with zoom and display of values on the curve point

Premium Version:
Additional events (armature voltage, excitation current, armature resistance) instead of only load torque events
Display an infinity of curves on the 2 graphs with selection of the color, the top/bottom position and the primary or secondary Y-axis of the graph. It is limited to 3 curves in the basic version
Load previously saved configuration, and also share them by email
Export data: graph images, graph data (xls/csv), machine parameters
And of course you help the developer, who is a teacher and researcher in electrical engineering, in his approach to develop educational apps.
