Motor Control Circuits [iPhone]

Motor Control Circuits is a mobile application dedicated to individuals in the field of electrical technologies to help them understand the various methods use for starting and controlling electrical motors.
To use this application, a basic knowledge of electrical technology is recommended.
This application is structured in to three separate tabs (Control methods, single phase symbols, three phase symbols)
The Control methods tab which contains a list detail view of various starting circuits with explanatory for each method.
You can learn and master the following symbols from this app:The other two tabs contains a list of single phase and three phase symbol of all devices in both EU and US/CAN standards used in the application respectively.
You can learn and master the following symbols from this app:
