Motor Type4-wire 2-phase stepper motor

Motorized filter mounts, stepper motor driven

The motor adopts an all-metal reduction gear design with high output torque
Stepper control provides precise angle control and repeat positioning
Unidirectional ultra-high resolution with rotation angle resolution ≤0.02 degrees

LBTEK Motorized Filter Mount for continuous neutral density filters. The mount utilizes a 10 mm 4-wire 2-phase micro stepper motor with an ultra-compact size, measuring only 18 mm in length and width, making it ideal for use in confined optical paths. Featuring an all-metal reduction gear design, the motor delivers high output torque. Stepper control converts pulse signals into precise angular rotation, ensuring accurate angle control and repeat positioning even in open-loop operation. With high resolution, the unidirectional rotational angular resolution can reach 0.015 degrees.
