| Abstract |
The performance of a four-quadrant controlled, 12 V, 20 W switched reluctance motor is presented. The drive basically consists of a 3-phase switched reluctance motor and a converter using only 3 power electronic switches (single switch per phase). A single programmable logic array together with some mono-stable integrated circuits are used for the four-quadrant control of the drive, including conduction angle control for increasing the speed range. The advantage of the drive is the simplicity with which four-quadrant control is obtained. However, it is shown that the power density of such a small switched reluctance machine (small in diameter) is low compared to machines with permanent magnet excitiation. |
