Description

Proven Bien-Air Reliability

The MC3 LED Micromotor has earned a reputation for reliability and longevity through years of successful clinical use.

Designed to provide consistent performance under demanding daily workloads, it remains one of Bien-Air’s most trusted electric micromotor solutions.

Wide Speed Range

The MC3 offers an exceptionally broad operating range from 60 rpm to 40,000 rpm.

This flexibility allows clinicians to perform a wide variety of procedures using a single motor, from low-speed polishing and finishing through to higher-speed restorative applications.

Smooth and Vibration-Free Operation

The motor is engineered to provide smooth rotation with minimal vibration across the entire speed range.

This helps improve operator control, enhances treatment precision and contributes to greater comfort during longer procedures.

Integrated LED Illumination

An integrated LED lighting system provides bright illumination directly at the treatment site.

The light intensity can be adjusted to suit different clinical situations, improving visibility and helping clinicians work with greater precision.

Compact and Ergonomic Design

Manufactured from stainless steel, the MC3 combines durability with a lightweight design.

Its compact dimensions and low weight help reduce hand fatigue while maintaining excellent balance and manoeuvrability during treatment.

Quiet Clinical Performance

With a maximum operating noise level of just 54 dBA, the MC3 supports a quieter surgery environment for both clinicians and patients.

Long-Life Bearing System

The micromotor uses lifetime-lubricated ball bearings to support long-term reliability and reduce maintenance requirements.

This helps maintain smooth operation throughout the motor’s service life.

Flexible Hose Rotation

The hose connection allows approximately ±400° of rotation, improving freedom of movement and reducing hose drag during treatment.

How the MC3 Brush Motor Works

The MC3 uses carbon brush technology to transfer electrical power to the rotor.

Electrical current passes through carbon brushes located within the stator and interacts with the magnetic field to generate rotation. This proven design delivers dependable performance across a wide speed range while maintaining smooth operation.
