Fully Auto Shut-off Brushless Electric screwdriver
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.
Fully auto shut-off brushless electric screwdriver:
- Non-carton brush motor;
- Long life
- Efficiency
- Low noise, no carbon brush friction, low noise
Drag cup brushless electric tool recover many brush tools faults
- Non-carton brush: do not produce carbon powder, no pollution, used by clean workshop
- Long life: no need to change the carbon brush, life is only limited by bearing life
- Efficiency: brushless motors with high efficiency, not too hot for long time working
- Low noise, no carbon brush friction, low noise
- No interference: when using not interference to power and other electronic products
- 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
- Good heat output, strong overload capacity
- Low electrical time constant
- Spare parts are using cylindrical structure, small but high-power
Non-carton brush electric screwdrivers structure feature:
- Drag cup DC brushless is made up of stator, rotor set, End cover, hall sensor.
- Prominent characteristics is the structure of the stator group. The stator group is made up of enclosure, stator punching, winding cup.
- Enclosure: Adopt stainless steel, rusty, no magnetic conduction, high strength
- Stator punching: Adopt annular silicon sheet, without gaps do not produce the cogging torque
- Winding cup: Enameled wire is cylindrical shape, enameled wire slot with higher rate
