Electric Motor Circuit Design

This app is a collection of interactive design tools for all components of electric motor circuits and controllers for both AC and DC motors as per electrical code.

This app can also be used to verify conformance of existing motor circuits and controllers to the electrical code. It can also be used as a design guideline for educational purposes.

All components of motor circuits are pictorially identified in the first diagram as they pertain to the installation of motors and each component is linked to series of interactive design tools via 3-D launch buttons. Each tool also comes with informational notes describing the design process.

Each button when pressed launches a series of tools for sizing of respected component of the circuit or controller shown.

All components of a motor circuit and controller can be designed with this app. The following is the list of interactive tools provided with this app:

1 - Full Load Ampere (FLA) rating
2 - Short circuit protection devices
3 - Branch circuit and conductor sizing for motor loads
4 - Feeder circuit and conductor sizing for several motor loads
5 - Overload protection devices
6 - Current rating of disconnecting devices
7 - Control circuit

With this app in your hands, designing a motor circuit according to the code is easier than ever. This app is all you need to engineer your own motor circuit quickly and with confidence.

This app is tested with all iOS platforms including iPhone, iTouch and iPad.
