Whether AC drill can use direct current

In general, AC drills cannot use direct current.

First, the difference between AC drill and DC drill

Ac drills use conventional AC power, while DC drills use DC power. Unlike DC power supplies, the voltage of AC power supplies changes with time, while the voltage of DC power supplies remains the same. In addition, when the AC drill is working, due to the structure of its motor, it must rely on the AC power supply to drive, while the DC drill can be achieved by the DC power supply.

Second, can use direct current to drive AC drill

Since the motor structure of AC drill is designed for AC power supply, in general, AC drill can not use direct current. If the DC power supply is forced to use, it will not only affect its normal working state, but also have an adverse effect on the motor winding and circuit. In addition, it may cause security risks.

However, some AC drills are designed to allow the use of direct current, and these drills can be converted by a DC converter. However, because this conversion will affect its performance and life, it is still recommended to use AC power when it is not necessary.

Why is it recommended to use AC power

In order to ensure the safety and performance of AC electric drill, it is recommended to use AC power supply. First of all, the AC drill is designed for AC power supply, the use of DC power supply may have an adverse effect on its motor windings and circuits. In addition, because the DC power supply voltage remains constant, it is easy to cause the mismatch between the heat and power consumption of the motor when it is used to drive the AC drill, thus affecting its normal working state. Finally, the use of DC power may have a bad effect on the battery life.

Iv. Summary

In general, AC drills cannot use direct current. Although some AC drills can be converted by a DC converter, it is recommended to use AC power. This can ensure safety and performance, and can extend the service life of the drill.
