The Heden M21VE-L 512-3.3k Digital Servo Motor is Hedén's smallest and lightest motor for professional film and broadcasting cameras. Its light weight and compact form factor make the M21VE-L a popular choice for drone operators. While the larger M26VE features higher torque for heavier lens gears, the M21VE-L is a better choice when a smaller, quieter motor is needed.

The M21VE-L mounts vertically on a 19mm (0.75") support rod without the need for tools. The accompanying bracket reduction insert will fit on a 15mm (0.59") support rod, and additional sizes are available (sold separately). Interchangeable snap-on gears can be mounted on either side of the gear housing, adding to the versatility of the motor. This motor is supplied with a 0.8 gear module (0.4, 0.5, and 0.6 modules available; sold separately).

IMPORTANT NOTE: This version of the motor features a 512 encoder, 3.3k id-resistor design (M21-110) for use with Hedén Carat and Preston systems.
