Computer aided drive of SRM(4/3) ( Switched Reluctance Motor )Via printer port- LPT

In this paper the control system of the switch reluctance motor ( SRM ) has been studied and executed, and driven by computer through the printer parallel port (LPT), and a simple explanation for switch reluctance motor has been introduced also it's work principle and some of its advantages and disadvantages with presenting some samples, where suitable electronic circuits, pulses generation circuits, isolation circuits between computer and power circuits has been executed, with suitable programming for controlling the whole system, then suitable measurements for monitoring have been done like currents, voltages, motor speed and recorded to be discussed.
