Gearboxes

Gearboxes are important components in the optimisation of electric motor performance, facilitating speed reduction, torque multiplication, and directional control through the use of gears with different ratios. These ratios determine the relationship between the rotational speeds of the motor shaft and the output shaft of the gearbox, influencing the output torque and speed. 

Dunkermotoren supplies a large range of gearboxes, designed to operate with their lineup of electric motors and drive systems. From planetary type (PLG) to Spirotec type (STG) and Worm type (SG) gearboxes, each variation is designed to meet distinct application requirements. 

Whether you're seeking high torque transmission, precise speed control, or compact design, Dunkermotoren's gearboxes deliver the versatility and reliability demanded by diverse industrial environments.

Rely on Powerbox's team of experts to guide you in selecting the ideal gearbox for your specific application needs, ensuring unparalleled performance, reliability, and efficiency for your industrial systems.
