AMEXORS Wireless LED Endodontic Motor 16:1 Mini Contra-Angle Brushless 120-500 RPM Auto-Reverse Reciprocating
Driven by a cordless brushless motor, this endodontic handpiece delivers adjustable rotational speeds from 120 to 500 RPM and torque control from 0.6 to 4.0 N·cm across 6 programmable working modes. It integrates a 360-degree rotatable 16:1 mini push-button contra-angle with built-in LED illumination to improve posterior access and canal orifice visibility during rotary and reciprocating instrumentation.

Brushless Drive Architecture and Multi-Kinematics Compatibility The AMEXORS Wireless LED Endodontic Motor utilizes an internal brushless drive mechanism engineered to maintain stable rotational speed (120–500 RPM) and calibrated torque output (0.6–4.0 N·cm) during root canal shaping. Through its 6 programmable memory modes displayed on the integrated OLED screen, clinicians can configure the motor for both 360-degree continuous clockwise NiTi rotary systems and asymmetrical reciprocating file systems.
Automated Torque Control for Instrument Protection To reduce the risk of torsional file separation in constricted or curved canals, the motor incorporates automated torque-sensing kinematics:
Auto-Reverse & Auto-Forward: When torsional resistance on the NiTi file reaches the preset torque limit, the motor automatically reverses rotation to disengage the flutes from the dentin wall, then resumes forward rotation once torsional load is relieved.
Auto-Stop: Halts file rotation immediately upon reaching the preset torque threshold, allowing manual withdrawal and canal irrigation.
360° Rotatable 16:1 Mini LED Contra-Angle Designed for posterior molar accessibility in patients with restricted mouth openings, the detachable 16:1 reduction mini contra-angle features a compact head profile and a push-button chuck for standard Φ2.35mm latch-type endodontic files. The contra-angle rotates 360 degrees around the motor shaft so clinicians can align the head angle with any dental quadrant while keeping the OLED screen in direct view. An integrated LED module on the contra-angle neck casts direct illumination onto the pulp chamber floor, and the detachable contra-angle head is fully autoclavable up to 135°C.
