In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Part 2 considers the design of the circuit and coding for the project's stepper motor controller.] 3.5 Speed-Controlled DC Motor with Tach Feedback and Thermal Cutoff E-2's main propulsion system ...

In this circuit, three sense resistors have been implemented, to measure the currents in each motor phase. Depending on the control algorithm, these may or may not be needed, for example in the case ...

Part VI of Art. 430 contains modifications of the general requirements and applies to particular conditions of motor control circuits. Motor control circuit conductors (larger than 10 AWG) that extend ...
