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
