Alternative forms of solid-state motor controllers have been presented in this paper including the effective use of read only memories in stepper motor controller implementations. An innovative low-cost universal stepper motor controller capable of controlling any kind of stepper motor has also been featured. The treatment includes a way of achieving a time-multiplexed control of several stepper motors with one universal controller and a method of generating a predetermined sequence of control bit-patterns for a dedicated application.
Key words: Motor controller, memory, stepper motor
