ELEC 1610 Electrical Motor Controls

This course provides instruction in alternating current (AC) and direct current (DC). Students identify motor control components, and explain their function and operation. Students will be expected to draw electrical schematics to meet given specifications and then use their schematics to wire the control and power circuits. Students will verify proper operation of circuits and use multi-meters and electrical schematics to troubleshoot and repair various circuits. Prerequisite: Completion of ELEC 1600. (4 lect., 2 lab)
