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 ...

End update Safety note for folks not used to working with the mains: All electronic parts of this DC-51 motor controller circuit are connected to live mains and could kill you. This blog and its ...

smooths motor running and prolongs brush life by dramatically reducing peak currents and commutator arcing. (This document from Elhand is helpful) Not knowing this, I previously adapted a cheap ‘DC51’ ...

This triac-based 220V AC motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. The speed of the motor can be controlled by changing the ...

This PWM Controller circuit is ideal for controlling small motors with 2A maximum current consumption. For higher currents you need additional cooling for T2 and increase C2 value. This pwm motor ...

Implement the motor and accompanying rotary sensor into a motor control circuit in both hardware and software. Add a motor and motor control circuit into a microprocessor based development kit. Create ...

or the motor itself. In Part 2, we’ll address reading basic to more complex control circuit diagrams and show you how to develop a logical and systematic approach to troubleshooting control circuits.
