2、 Overview of DD motor

DD motor, also known as direct drive motor, is a type of motor that directly connects the rotor of the motor to the load. It eliminates

intermediate links such as gears and belts in traditional transmission systems, directly transmitting the rotational force of the motor to the

load. DD motors have the characteristics of high precision, high rigidity, high response speed, and simple maintenance.

Working Principle:

The rotor of DD motor is directly connected to the load, eliminating the intermediate transmission link.

Due to the absence of transmission losses, DD motors can achieve high-precision position control.

Design features:

No intermediate transmission reduces transmission losses and improves efficiency.

High precision, due to the absence of transmission links, high-precision position control can be achieved.

High rigidity, directly driving the structure improves the rigidity of the system.

Easy to maintain, due to its simple structure, the maintenance cost is relatively low.

High response speed, directly driving the structure improves the system”s response speed.
