ates can be combined). The rate of clock pulses determines the motor"s rpm. Switching transistors can replace the relays to increase the circuit"s efficiency. This circuit drives a stepper motor whose speed depends on clock rate. Standard SSI LSTTL chips are used. Switching transistors can be used in place of the solid-state relays to improve the circuit"s efficiency.
