A circuit diagram of a driving motor using a variable DC source. When using a PWM source, the circuit sees Ohmic resistance and inductance due to frequent switching .

Prior knowledge needed: ECEA 5340 Sensors and Sensor Circuit Design. Learning Outcomes. Understand how to specify the proper AC or DC motor for a machine design. Integrate the motor to a machine, ...

Q 2, D 1, and R 3 constitute the braking circuit. This circuit is similar to the output circuit of TTL gates. D 3 protects Q 2 from inductive surges. When S 1 closes, Q 1 turns on, and the voltage at ...
