Project Background
Thanks to electric screwdrivers' core features of high efficiency, labor-saving operation, and precise control, they have become indispensable tools for manual assembly, home appliance repair, and industrial production.Compared with traditional manual screwdrivers, they offer distinct advantages: They greatly boost assembly efficiency and ensure consistent torque control, thus reducing product damage from human error and cutting down worker fatigue. By power source and control mode, they are split into four main types: corded models offer strong power for heavy industrial use; cordless versions are portable and flexible for home DIY; fully automatic types come with torque adjustment, ideal for precision electronics assembly; semi-automatic models feature simple structures for basic fastening tasks. As the core component of electric screwdrivers, DC motors directly determine the performance of electric screwdrivers. HongYang RS-380, RS-390 and other series of DC motors for electric screwdrivers have gained widespread trust and preference due to their excellent torque, speed and outstanding stability.
How Does 380 Motor Drive an Electric Screwdriver?
DC motors for electric screwdrivers convert electrical energy into mechanical energy to drive the screwdriver’s rotational motion. On the market, they are powered either by batteries (cordless) or direct AC power. When current flows into the motor’s stator windings, a stable magnetic field is generated. The rotor (equipped with permanent magnets) cuts through these magnetic lines, making the armature rotate,and the force from this rotation is transmitted directly through the motor shaft to the screwdriver bit, driving it to spin and fasten or loosen screws.
Advantages of 380 DC Motor in Electric Screwdriver
1.High Efficiency:The RS-380 DC motor for electric screwdrivers is built with high-strength galvanized steel, premium magnetic tiles, and magnet retainers, paired with strict precision manufacturing processes. This combination delivers exceptional efficiency and energy conversion rates, minimizing power waste for both cordless and wired electric screwdrivers.
2.High Torque:Due to its purpose-built optimized design, the RS-380 DC motor for electric screwdrivers delivers ample torque even at low voltage and low current. It’s fully suited for electric screwdrivers and other complex use cases.
3.Compact Size:The RS-380 DC motor for electric screwdrivers features a diameter of 27.7mm (no more than 30mm with the magnet retaining ring and a length of 38mm (excluding the shaft), making it a perfect fit for small size electric screwdrivers. Of course, we also offer motors in other sizes to meet your specific needs.
4.Low Noise:Leveraging optimized manufacturing processes and noise reduction technologies, the RS-380 DC motor for electric screwdrivers effectively minimizes noise and vibration during operation, perfectly meeting users’ customized requirements.
