In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit ... and realistic control circuit you’ll find in the field. To begin troubleshooting, first gather up the most recent ...

The proper selection of 3-phase solid state relays for motor control application depends not only upon a comprehensive understanding of 3-phase SSRs, but also of the 3-phase power system and ...

Integrate the motor to a machine, based on analysis of motor equations for voltage, current, torque and speed. Implement the motor and accompanying rotary sensor into a motor control circuit ... AC ...

This can help to isolate the problem to the power supply, the control circuit, or the motor itself. In Part 2, we’ll address reading basic to more complex control circuit diagrams and show ... for the ...
