Technical Specifications

Key Features & Advantages

High Torque & Powerful Vibration Output

The RF-4260 delivers substantial torque through its optimized electromagnetic design and high-performance magnetic rotor construction . With a stall torque rating of 1330 g.cm at 12V, this motor provides strong starting torque and consistent vibration intensity even under load . The combination of high-quality magnets and precision-balanced rotor assembly ensures maximum vibration amplitude for haptic feedback applications.

Built-in Internal Driver for Easy Integration

Unlike traditional motors requiring external drive circuitry, the RF-4260 features an integrated brushless driver IC that simplifies installation and reduces overall system complexity . This intelligent on-board control provides:

• Speed control via analog voltage (0-5V) – proportional speed adjustment for precise vibration intensity control

• Forward/reverse direction control – flexible operation modes for varied application requirements

• FG signal output – Hall-based speed feedback (6 square wave pulses per revolution) for external speed monitoring

Brushless Technology for Extended Service Life

The RF-4260 utilizes electronic commutation with built-in Hall sensors, eliminating mechanical brush wear and oxidation issues common in conventional brushed motors . This design delivers significantly longer operational lifespan and higher reliability in continuous-duty applications . Advanced protection features include automatic PWM startup for full torque delivery and thermal shutdown (TSD) protection against overheating .

High Vibration Output in Compact Form Factor

Engineered with a high-performance magnetic rotor paired with precision components, the RF-4260 achieves greater vibration mass and moment compared to traditional motors of similar size . The result is stronger, more responsive vibration feedback ideal for wearable devices and portable electronics where space is limited but tactile response is critical.

Low Noise & Smooth Performance

The brushless design provides quiet, smooth operation with minimal acoustic noise and mechanical vibration interference—essential for consumer electronics, medical devices, and precision instruments.
