Application of N30 Motor in Pen-Type Electric Screwdrivers

Pen-type electric screwdrivers are mainly used for light-load products such as mobile phones, tablets, laptops, watches, drones, cameras, game consoles and electric shavers. The forward and reverse functions of the electric mode allow quick installation and removal of small screws.

The core working components are the PCB control board, DC brushed motor + gearbox, and various screwdriver bits. For DC brushed motor selection, we recommend the N30 DC brushed motor.

This motor measures 12*10*20mm, and its slim shape fits the pen-style design. The operating voltage can be selected from 1-24V, and the speed can be chosen within 20000rpm. With a gear ratio of 50:1 to 80:1, it delivers a torque of 3-5Nm, ensuring sufficient power and efficient operation.

Price is also a top priority for many manufacturers. A pen-type electric screwdriver is priced at 40-80 RMB, so costs must be considered from the R&D stage, including PCB board, DC brushed motor + gearbox, various screwdriver bits, and housing costs.

The cost of the N30 brushed motor is 2-4 RMB. While fully meeting performance requirements, prioritizing cost reduction helps gain an advantage in the market.

However, brushed motors also have obvious drawbacks. The carbon brushes and brushes used have a service life of only 300-800 hours, while brushless motors can last more than 2000 hours, but their cost is 10 to 20 times higher than that of DC brushed motors. This is why choosing brushed motors helps gain an edge in the competitive market under most market conditions.
