A torque motor, also known as a direct drive motor or torque motor, is a special electric motor developed for applications where high torque and precise speed control are required. Unlike conventional electric motors, which are connected to the system to be moved via a gear stage or a coupling, the torque motor is connected directly to the load. This eliminates the losses caused by friction in the gear stages and results in higher efficiency.
The torque motor consists of a stator, which generates an electromagnetic field, and a rotor, which consists of an arrangement of permanent magnets. The rotor is attracted by the magnetic field of the stator and moves accordingly. As the rotor is connected directly to the load, the maximum torque is transmitted directly to the load.
Torque motors are used in various applications, particularly in automation technology and robotics. They are particularly suitable for applications where high precision and dynamics are required, such as in machine tools, packaging machines or robots. As torque motors can react very precisely and quickly to changes in the control system, they are able to generate precise motion profiles that can help to improve production processes.
