Käigukastimootorid

A käigukastimootor, often translated as gearbox motor or geared motor, is an electromechanical device that combines an electric motor with a reduction gear. The primary function of the gear reduction is to decrease the speed of the motor's output shaft while simultaneously increasing its torque. This is achieved by a series of gears within the gearbox, which transmit rotational motion from the motor's high-speed, low-torque output to a lower-speed, higher-torque output.

These integrated units are widely used in applications where high torque is required at low rotational speeds. Examples include conveyor systems, robotic actuators, electric wheelchairs, industrial machinery, and various types of automation equipment. The compactness of a käigukastimootor is a significant advantage, as it integrates both the power source and the torque multiplication mechanism into a single unit, simplifying design and installation.

Käigukastimootorid can be powered by various types of electric motors, including DC motors, AC motors, and stepper motors. The specific type of motor and the gear ratio chosen depend on the application's requirements for speed, torque, power consumption, and operational environment. The gearbox itself can be constructed using different gear types, such as spur gears, planetary gears, or worm gears, each offering different characteristics in terms of efficiency, noise level, and torque capacity. Maintenance typically involves lubrication of the gear components and occasional inspection for wear.
