Alternating current 710W impact drill

Is the AC hand drill motor brushless

Some brushless motors, some are not.

First, the working principle of alternating current hand drill motor

Ac electric hand drill is a hand drill using AC power supply, its motor is an AC motor, its working principle is to use the AC power supply provided by the change of power to drive the motor rotation.

Simply put, when the motor rotates, the coil in the stator will form a rotating magnetic field under the action of the AC current input to the power supply; At the same time, the conductor in the rotor will also be induced electromotive force due to the action of the magnetic field, which will produce a current, which will interact with the rotating magnetic field, so that under the interaction of the two rotating magnetic fields, the motor can rotate.

Second, the characteristics of brushless motor

Brushless motor is an important technology in the field of modern motors. Compared with traditional brushless motors, brushless motors have the following advantages:

1. High efficiency: The brushless motor uses electronic commutation, replacing the mechanical commutation of the traditional brush, making it more efficient;

2. Longer life: Because the brushless motor has no brush, it is not easy to damage, and the service life is longer than that of the brushed motor;

3. Less noise: the rotor structure of the brushless motor is simpler and less noise;

4. Wider speed range: The brushless motor controller can achieve soft start and frequency conversion speed regulation of the motor, making its speed range wider.

Third, whether the AC electric hand drill motor is brushless motor

In fact, some AC hand drill motors use brushless motor technology, and some are not. According to the circuit scheme and equipment requirements used, power tools using brushless motors will have better performance, such as high efficiency, low noise, long life and so on.

When purchasing an AC electric hand drill, you can understand the type of motor of the selected product by querying the product manual or asking the after-sales staff, so as to better select the power tools that meet your personal needs.

【 Conclusion 】

Ac electric hand drill motor is not necessarily brushless motor technology, but the use of brushless motor power tools will have better performance, such as high efficiency, low noise, long life and other characteristics. When purchasing an AC electric hand drill, it is necessary to understand the type of motor of the selected product in order to better meet individual needs.
