The booming development of the industrial robot industry has also led to the development of related upstream industries. As an important component of industrial robots, servo motors require maximum power-to-mass ratio and torque-inertia ratio, high starting torque, low inertia and relatively wide and smooth speed range. There are currently many manufacturers of servo motors, but not all of these servo motor products can be used in industrial robots. Let’s take a look at the well-known brands of servo motors for industrial robots.
1. Lenze
Lenze AG is one of Germany's leading industrial innovation companies, focusing mainly on products, solutions, systems and services for mechanical and electronic drives. Lenze's product range includes frequency converters, servo drives, reducers, motors, brakes and clutches.
In addition, it uses automation solutions that integrate software, visualization and control, as well as system engineering, coupling technology and services. Since its founding in 1947, drive and automation systems have been Lenze's core competencies, making it one of the most innovative companies in the industry.
