How to Control the Speed of a DC Motor Using IC L

The circuit also becomes very favorable for operating and controlling small portable DC drill machines like PCB drilling machines. No guarantee is given that the information is from the latest issue of those sources or about the accuracy of those sources.

Interest will be charged to your account from the purchase date if the balance is not paid in full within 6 months. Learn More – opens in a new window or tab International shipping and import charges paid to Pitney Bowes Inc.

Noise interference is checked by introducing the capacitors C1, C2, C3, and R4; however a few of these may be omitted for specific loads, which will discussed in the later part of the article.

Preferably P1 is adjusted immediately after the motor starts and before its armature warms up to its normal temperatures and results in an increase in its internal resistance. Watch list is full. Disclaimer Conditions of Sale Conditions of Purchase.

Add to watch list. The speed control described here actually happens due to the voltage drops across the internal resistance Ri of the motor. With loads having built-in noise suppressors, C2 may be excluded and R5 added for protecting the op amp against sudden differential voltage peaks. Metal Film Axial Resistors.

Image not available Photos not available for this variation. The circuit uses a dual symmetrical supply which facilitates datasheeg quadrant operation of the connected motor. See all condition definitions k165 opens in a new window or tab Here the use of 24 and higher volts becomes necessary and therefore the application becomes perfectly compatible with the present design.


The IC being subjected to high currents may heat up considerably and therefore should be mounted over a suitably large heatsink. Therefore some careful optimization techniques become essential for deriving optimum response from the circuit. Copyright Wilsons Ltd.

Thus here the motor is made stationary by keeping the slider arm of the pot VR1 exactly at the center and then using incrementing or decrementing motions by shifting it to daatasheet relevant directions, i.

The circuit is reasonably balanced and further modifications are not recommended, which may possibly and easily induce a lot of instability in the design. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.

We recommend using the latest version if you don’t already have it. The figure on the left shows one practical design using the IC L which is a power op amp designed for handling output powers up to 3 amps at a maximum voltage of 36 V, and which eminently suits the proposed application.

Experimenting with R4, C3 by eliminating them initially can prove useful for drill machines where the inclusion of C2 becomes quite handy. Material supplied by the Company may vary significantly from this data, but will conform to all relevant and applicable standards. Add to watch list Remove from watch list.

A motor being a complex device with varying torques and back EMFs, the rotor introduces a considerable capacitance.
