[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo ... this assembly has a weight and torque advantage over a NEMA 17 sized stepper motor, but we see no hard data ...

Some of the nuggets we get are the linear relationship of torque to current (10-15A max) and speed to voltage (12-15V DC) on these units, and some of the ways the wiring in these motors is a ...

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