Ideal for microscope stages that require precise positioning. Unlike electromagnetic motors, the movement is generated by frictional contact, and therefore the motor is not affected by magnetic fields. Optimal for applications in environments with strong magnetic fields such as MRI and other medical equipment. This small, lightweight, low-speed, high-torque motor adopts a unique drive mechanism developed by NIKKO that does not require a gearbox at low speeds. This allows for a motor with low-speed, high-torque functions in a small and lightweight body. Without the use of gears, noise is minimal, and movement is silent. The frictional contact maintains torque without power, allowing to keep the position during power off.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/section>\n\n\n\n<section class=\"l-section
