Heketai‘s SS14 and 1n4148 Diodes, S8205A or Hktq65n03 and Hktd120n04 Mos Products Can Be Used in Electric Drills
As a common electric tool product, the manufacturing technology and scheme of electric drill are mature. The principle of electric drill is mainly based on the drive of electromagnetic rotary or electromagnetic reciprocating small-capacity motor, and the rotating force of the motor is transmitted to drive the drill bit to rotate to scrape objects. An electric drill usually consists of a motor drive part, a transmission part, a drill bit, a key system and a charging management. In the electric drill, many semiconductor products are used, including diodes, triodes, MOS tubes, resistors, capacitors, chips and so on.
Take the common electric drill drive board scheme as an example. It uses brushless motor, and the BOM table consists of chips, diodes, triodes, MOS tubes, capacitors, resistors, indicator lights and other products.
In this scheme, Heketai's SS14 and 1N4148 diodes, S8205A or HKTQ65N03 and HKTD120N04 MOS products can be used.

Electric drills usually use diode rectifier, which is often used in rectification, detection, voltage stabilization and other circuits in electric drills. It can convert alternating current into direct current and provide a stable direct current power supply for the motor. In electric drills, triodes are often used in amplification circuits to amplify weak control signals to drive motors or other loads, and can also be used in switching circuits to control the start and stop of motors. MOS transistor has the advantages of high input impedance, fast switching speed, low driving power, etc. In electric drills, MOS transistor is often used to drive motors, and the precise control of motor speed and steering can be achieved by controlling its gate voltage.
The electric drill depends on the rotating torque of the motor and the power of the transmission system, and realizes the purpose of drilling or tightening screws through the interaction between the drill bit and the workpiece to be processed. In the process of use, it is necessary to pay attention to selecting the right bit and adjusting the appropriate speed to achieve the best effect.
A good electric drill should be more durable, stable and powerful. This requires discrete device products to be more reliable and stable. As a manufacturer specializing in the production of discrete devices, Heketai's diodes, MOS and other products have been widely used in electric drills and are customers' quality partners.
