Troubleshooting Motor Control Circuits — Part 1 Isolating problems in the main power circuit Feb. 16, 2015 5 min read ...

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 ...

In Part 1, we’ll discuss some general recommendations for designing PCBs that use motor-driver ICs, which require special cooling techniques to handle the power dissipation.

Printed circuit board layout of the motor speed controller Another version found here. If the main use for this circuit is to control the brightness of a light bulb, RS and CS are not necessary.

When designing a motor control circuit, it’s vital to determine how to deliver the high current required to drive the motor. Designers must choose whether to use monolithic integrated circuits (ICs) ...

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 ...
