ARRI cforce MAX Motor Unit

High-Performance Lens Control for Professional Cinema

The ARRI cforce MAX Motor Unit is a high-performance lens motor engineered for precise focus, iris, and zoom control. Combining exceptional speed with high torque, this compact unit is built to handle the most demanding cinema workflows, from handheld rigs to complex studio configurations.

Advanced Brushless Technology and Precision

Equipped with an advanced brushless motor, the cforce MAX achieves speeds of up to 400 teeth per second. This makes it the ideal choice for fast focus tracking and managing mechanically demanding lenses, including large cine primes, heavy zooms, and vintage glass that requires extra strength without sacrificing accuracy.

Intuitive Interface and Seamless Integration

The integrated touchscreen interface allows for immediate setup, configuration, and status monitoring directly on the motor body. A physical soft-touch button provides rapid access to essential functions, while manual calibration support ensures the protection of sensitive optics during initialization. Dual LBUS ports facilitate flexible daisy-chaining and integration into existing ARRI ECS and Hi-5 ecosystems.

Versatile Mounting and Compatibility

Designed for maximum versatility, the cforce MAX is compatible with 15mm or 19mm support rods via ARRI motor clamps like the MRC-1. It integrates seamlessly with the ALEXA 35, ALEXA 35 Live, ALEXA 35 Xtreme, ALEXA Mini, ALEXA Mini LF, and cforce mini RF. The unit operates within a 10.5-34V DC range and is built to withstand extreme environments from -20°C to +50°C.
