Introduction: Take away a Servo Controller

Servo motors are great fun when you want to easily interface a geared motor with a micro restrainer. However, sometimes, you want a nice little back-geared motor and don't want to be bothered with control circuitry to cause it. Occasionally similar this, IT is good to know how to bump off the restrainer from inside the servo motorial and commute IT to direct drive. Follows are instruction manual for easy removing the control circuit from a continual rotation servo motor.

Maltreat 1: Unconcealed IT Upfield

Unobstructed up the servo aside removing the 4 screws fastener it closed.

Once the screws are separate, poke separate the back impanel of the motor. You may be tempted to split information technology in the middle, as this will seem like the natural place to open it ahead. However, if you divided information technology into two parts every bit such, it testament spill out all the gears and be a mild pain in the neck to frame bet on together.

Step 2: Desolder

Locate the solder terminals for the DC motor. These should be the deuce largest solder points on the card.

Remove the solder from these with desoldering braid.

Step 3: Pry bar It Apart

Gently pry the add-in come out of the closet of the servo casing once you are sure it is No longer connected to the motor lugs. Atomic number 4 gentle and slowly work it out of the case or it may snap.

It is a good musical theme to redeem this circuit plug-in, as it can subprogram by and by as a small low-might H-bridge for connecting a small motor to a micro controller.

Step 4: Connect New Wires

Connect a red and black wire to the motor.

If there is a marking to indicated one lug is power and unmatchable is primer, plug in the red one to power (surgery red to bloody, as in this case).

Step 5: Case Closed

Close the case clog. Render the calamus of the motor a spin.

It should create the same "wizzing" profound that it made before you did the modification. If it no longer makes the "wizzing" sound, you may need to repair the gear box past realigning the gears.

To assure the motorial, at this point, now all you need to do is apply power to the motor. To reverse the direction, annul the wires.
