The ARRI CLM-4 (Controlled Lens Motor) is a robust and versatile lens motor designed for professional cinematography. It serves as a middle-ground workhorse in ARRI’s Electronic Control System (ECS), offering a balance of high torque and quiet operation. Unlike the LBUS-based cforce motors, the CLM-4 uses a standard CLM connection, making it the primary choice for legacy systems like the ALEXA Plus and universal motor controllers.
Key Features and Benefits
Modular Design: The motor unit, gears, cables, and brackets are all independent, allowing for easy maintenance and flexible rigging.
Quiet & High Torque: Powerful enough to drive stiff vintage glass while remaining silent enough for dialogue-heavy scenes.
Flexible Gear Placement: Drive gears can be attached to either side of the motor, allowing it to be mounted above or below the lens in tight camera configurations.
Broad Compatibility: Works seamlessly with ARRI UMC-4, SMC-1, and WCU-4 controllers, as well as Alexa Plus and Studio camera bodies.
Interchangeable Gears: Supports multiple gear mods (0.8, 0.6, 0.5, and 0.4) to accommodate standard Cine lenses as well as ENG-style lenses.
Universal Mounting: Features a clamp that fits both 19mm and 15mm rods via an included insert.
