This is a brand new electric screwdriver range from Sumake featuring a new brushless motor. The benefits of this new motor design are to

improve durability and offer a wider range of torque and r.p.m - this is because in brushless motors commutation is achieved electronically

and therefore they are capable of very high speeds and torque without arcing.

As brushless motors have a lower thermal resistance they are able to operate in a much wider temperature range and will achieve a

higher duty cycle. No brushes also mean a reduction in maintenance and no brush contamination to the bearing or environment

which also makes this screwdriver safer when in contact with fluids due to the elimination of arcing.

Lastly due to the lower thermal resistance, these drivers are capable of operating in wider temperature ranges, have higher torque

to inertia ratios, and greater acceleration. The smaller brushless motor can do the same job as their much larger counterparts

would otherwise be used for - this also results in a reduction in costs.

Power supply with screw counter function - compatible with PLC based process control system, accurate counting of screw fastening, settable running speed and timing. Buzzer alert on completion of fastening cycle and unfinished screwcounts. Simulated learning feature to assist with best setting value.

Power supply with integrated screw counter, counts 1-99, count up and down. High and low running speeds, alarm function. Suitable for large torque models.
