Economical Brushless Electric Screwdriver
The most direct change of the brushless motor is to remove the electric spark generated when the brushed motor is running, which greatly reduces the interference of the electric spark on the remote control radio equipment.
Low noise and smooth operation. The brushless motor has no brushes, the friction force during operation is greatly reduced, the operation is smooth, and the noise will be much lower. This advantage is a huge support for the operation stability of the Electric Screwdriver. Long life and low maintenance cost. Without the brush, the wear of the brushless motor is mainly on the bearing. From a mechanical point of view, the brushless electric batch is almost a maintenance-free motor. When necessary, only some dust removal maintenance can be performed. The brushless electric screwdriver uses a high-quality brushless motor, which is the perfect solution for use in a clean room. It has zero emission of coal dust in the working environment and will not pollute the working environment. At the same time, the clutch control method ensures that the torque control error is less than ±7%, and has a very long service life. Very small and light weight, making the operation very comfortable, low noise, low vibration, high safety, continuous use, no maintenance.
