Product Abstract:

Fully auto shut-off electric screwdriver with Non-carbon brush motor, high quality, long use life and competitive price... As Driven by imported brushless motor, this device is uniquely designed in the concept of energy-saving, high-efficiency and environmental protection as well.


Product Description

Fully auto shut-off brushless electric screwdriver: 
1,Non-carton brush motor; 
2, Long life 
3, Efficiency 
4, Low noise, no carbon brush friction, low noice

Drag cup brushless electric tool recover many brush tools faults

1.1, Non-carton brush: do not produce carbon powder, no pollution, used by clean workshop

1.2, Long life: no need to change the carbon brush, life is only limited by bearing life

1.3, Efficiency: brushless motors with high efficiency, not too hot for long time working

1.4, Low noise, no carbon brush friction, low noise

1.5, No interference: when using not interference to power and other electronic products

1.6, Simple and excellent clutch performance: the electronic control precision and realize on-off to stop using force and the small, long time holds no fatigue

 

The advantages of the non-carbon brush compared with traditional electric batch brushless

2.1 Good heat output, strong overload capacity

2.2 Low electrical time constant

2.3 Spare parts are using cylindrical structure, small but high-power

 

Non-carton brush electric screwdrivers structure feature:

3.1, Drag cup DC brushless is made up of stator, rotor set, End cover, hall sensor.

3.2 Prominent characteristics is the structure of the stator group. The stator group is made up of

enclosure, stator punching, winding cup.

3.3, Enclosure: adopt stainless steel, rusty, no magnetic conduction, high strength

3.4, Stator punching: adopt annular silicon sheet, without gaps do not produce the cogging torque

3.5, Winding cup: enameled wire is cylindrical shape, enameled wire slot with higher rate
