Direct Drive (DD) motors are a breakthrough in motion control technology, offering high precision, efficiency, and reliability. Unlike traditional motors that rely on mechanical transmission components like gears or belts, DD motors directly couple the load to the rotor, eliminating backlash and reducing maintenance. These motors are widely used in robotics, industrial automation, CNC machines, and even consumer electronics like washing machines.
A Direct Drive motor is an electric motor where the load is directly connected to the rotor without any intermediate mechanical components. This design minimizes energy loss, reduces wear and tear, and enhances performance. DD motors can be either rotary (torque motors) or linear, depending on the application.
