Push Button Motor Control Circuits

  The circuits on this page are for motor controls using Push buttons and would typically be found in commercial and industrial installations.

  The circuits do not show the wiring of the motors themselves as this depends on the particular motor type. The type of motor also governs the number of contacts needed for the motor side of these circuits.

  The "Relay Holding Contacts" and the "Interlock Contacts" shown in these circuit would normally be built into the motor control relays.

  The Forward / Reverse control circuit would normally have a time delay built into the interlocks so that the motor and its load would have time to slow to a stop before the direction could be reversed. In some cases this delay also applies to restarting the motor in the original direction as well.

Please Read Before Using These Circuit Ideas

  The explanations for the circuits on these pages cannot hope to cover every situation on every layout. For this reason be prepared to do some experimenting to get the results you want. This is especially true of circuits such as the "Across Track Infrared Detection" circuits and any other circuit that relies on other than direct electronic inputs, such as switches.

  If you use any of these circuit ideas, ask your parts supplier for a copy of the manufacturers data sheets for any components that you have not used before. These sheets contain a wealth of data and circuit design information that no electronic or print article could approach and will save time and perhaps damage to the components themselves. These data sheets can often be found on the web site of the device manufacturers.

  Although the circuits are functional the pages are not meant to be full descriptions of each circuit but rather as guides for adapting them for use by others. If you have any questions or comments please send them to the email address on the Circuit Index page.
