Also noise suppressing components tend to increase the complexity, resulting in instability of the motor movement occasional stuttering.

Experimenting with R4, C3 by eliminating them initially can prove useful for drill machines where the inclusion of C2 becomes quite handy.

How to Control the Speed of a DC Motor Using IC L165

A motor being a complex device with varying torques and back EMFs, the rotor introduces a considerable capacitance. The circuit is reasonably balanced and further modifications are not recommended, which may possibly datashfet easily induce a lot of instability in the design. The circuit uses a dual symmetrical supply which facilitates two quadrant operation of the connected motor. Other offers may also be available. Mouse over to Zoom – Click to enlarge.

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 the relevant directions, i.

Please enter 5 or l1655 numbers for the ZIP Code. This Data is indicative only and as such is not to be relied upon in place of the full specification. The Ri compensator preset P1 is adjusted for stabilizing the rotations of the connected motor to a uniform level.

With loads having built-in noise suppressors, C2 may be excluded and R5 added for protecting the op amp against sudden differential voltage peaks. Thus we find that when such a motor is loaded, the current datasehet rises resulting in an increased voltage drop across its winding which ultimately affects and drops the supply voltage significantly.

Ideally, the speed of DC motors having very low internal resistance is directly proportional to the voltage applied and is not related to their torque.

Please note that the ‘Datasheet Update’ date shown above is no guarantee of accuracy or whether the datasheet is up to date. After connecting an appropriate load DC motorthe power is switched ON. Therefore some careful optimization techniques become essential for deriving optimum response from the circuit. Material supplied by the Company may vary significantly from this data, but will conform to all relevant and applicable standards.
