2, the two-speed electric drill refers to the electric drill motor is to use a carbon brush to contact the stator on the rectifier copper sheet to power the coil of the motor rotor and with the stator to form a rotating magnetic field, driving the rotor to rotate and form the drill bit rotation.
3, two speeds a low speed a high speed. Electric drill double speed is adjustable, a high speed, a low speed. You can choose the speed according to the width, low speed can save energy. And there's a little more two-speed now.
4, the difference in speed, such as drilling with a small drill, the speed difference is twice. Two speed is fast and slow, it's hard to punch holes in the iron,Single speed is unbeatable because it only has a fast gear. Low speed torque is large, high speed torque is small.
5, charging hand drill single speed is only one speed can not be adjusted, double speed can be adjusted, a high speed, a low speed. Electric drill is the use of electricity to do the power of drilling machine, its working principle is electromagnetic rotary or electromagnetic reciprocating small capacity motor motor rotor to do magnetic field cutting work operation, through the transmission mechanism to drive the operating device, drive the gear to increase the power of the drill, so that the drill scrapes the surface of the object, better penetrate the object.
2, Question: How to solve ikea lithiumBattery drill charging light is not bright problem? First, make sure the battery is fully charged. If the battery is fully charged but the charge indicator is still off, try the following steps: Check the switch on the drill body to make sure it is on. Sometimes the switch may be accidentally turned off, causing the charging light to fail. Next, carefully check whether the contact between the charging lamp and the drill is good.
3. The first step of the maintenance strategy for IKEA lithium drill is to confirm whether the charger is normally powered. If there is no problem with the charger, then check whether the charging line is intact, whether there is a break or the welding point of the component is unwelded. If none of the tests is abnormal, you may need to replace the battery to troubleshoot the problem. Battery Replacement Guide Before replacing a battery, determine the battery model.
