Need to size a motor? Use this simple formula: T = 9550 × P ÷ N. In this quick guide, we show how to calculate torque, speed, and power with real examples – like choosing a 750 W servo for 2 Nm at 3000 rpm, or working out 4.77 Nm from 1 kW at 2000 rpm. Perfect for engineers, integrators, and automation learners. For more robotics, components, science news, and technical tutorials, check out Eriksen.
