| This project uses a suitable power electronic converter, in combination with an encoder or tachometer, and feedback control, to produce a motor system that runs at an adjustable speed for a small mobility application. For example: a small motorized shopping cart, luggage cart or electric golf bag cart. The source is from a 12 V battery and control currents over a range of 0 to 50 A. The controller controls at least 90% efficient for motor loads in the range of 50 to 150 W. It also delivers 150 W continuously, 250 W for at least one minute, and up to 50 A at 10 V or more for at least 5 seconds without damage. If it is overloaded for a longer period, it should shut off automatically and require a reset by the user. Speed regulation allows a speed decrease of up to 10% for a load change of 0 to 150 W. Total parts cost of the converter does not to exceed $12. Moreover, a wireless remove control is used in this project. it uses RF transmitter and receiver on both the remote controller and the local motor speed control. Users are able to use the remove controller to achieve all the functions on the converter. |
