Alternating current 220V electric drill

How to convert AC hand drill into DC drill

First, material preparation

1. Dc power supply: Generally use 12V or 24V DC power supply, can choose lead-acid batteries or lithium-ion batteries, etc., can also buy a special power supply.

2. Motor controller: used to control the speed and direction of the motor, one-way motor controller or two-way motor controller can be selected.

3. Motor: Choose DC motor, power and speed should be determined according to actual use needs.

4. Wires, plugs, switches, etc. : used to connect and control circuits.

Second, modification steps

1. Open the shell of the electric drill and take out the original motor and circuit board.

2. Install the new DC motor and check whether the wiring is correct.

3. Install the motor controller and connect the cables according to the actual circuit requirements. If the reverse function is required, the corresponding switch and control circuit should be added.

4. Connect the power supply and use a multimeter to check whether the circuit is normal.

5. Repackage the shell of the electric drill and install the switch.

Third, precautions

1. Before modification, carefully read the manual of the electric drill to ensure its own safety and correct operation.

2. During the modification, pay attention to the safety of power supply and circuit, and use insulation tools and protective gloves.

3. Power polarity and motor steering should be confirmed before circuit connection to prevent motor damage caused by connection errors.

4. Solutions to common problems

1 motor does not rotate: may be circuit wiring error or motor failure, you can carefully check the circuit and motor.

2. The speed is unstable or too high: the motor controller may be set incorrectly, and the controller parameters should be confirmed or replaced.

3. Battery life is not long: the battery capacity may be insufficient or not properly charged, should be used to meet the requirements of the battery and charge correctly.

Through the above steps and precautions, you can successfully transform the AC electric drill into a direct current electric drill. It should be reminded that the modification of electrical appliances requires certain professional knowledge and skills, and it is recommended that the modification or guidance be carried out by professionals.
