Three-phase stepper motor control circuit


Posted on Mar 28, 2007

As it can be seen from the figure, + DC Solid State Relay (SSR) of the input stage is an opto-isolator, when the switch output is high, by inverting driver circuit goes low, so

there is a light emitting diode and the current through the light, the light of the photosensitive transistor is turned on, so that the collector generates an output voltage which can be used to control external circuitry. SSR power transistors for the output stage, the output voltage of up to 30 -180V. Step into the motor A, B, C three-phase, each phase consists of - a type SSR Yin flow control, respectively, by 8255 the port PAO ~ PA2 controlled.
