Direct drive motors can generally be divided into two types: frameless direct drive motors and housed direct drive motors. A frameless direct drive motor mainly consists of a stator and rotor. Users need to integrate components such as the rotor mounting shaft, encoder, and bearings, making system integration more complex but allowing a highly compact equipment structure and greater design flexibility.A housed direct drive motor integrates the stator, rotor, bearings, encoder, and motor housing into one unit. It is easier to install, align, and operate, making it suitable for applications requiring convenient integration. Compared with conventional motor-and-gearbox systems, direct drive motors simplify the mechanical structure by driving the load directly. They can improve positioning accuracy, dynamic response, and motion smoothness while reducing mechanical transmission components, production cycle time, and maintenance requirements.
