Power-to-weight ratio


The ratio of the output powers to weight of actuators.

The power-to-weight ratio is a criteria for evaluating the performance of actuators. The higher the ratio, the higher the output by lighter devices. Generally, the larger the device, the greater the increase in the proportion of the section relating essentially to the energy conversion and the smaller the proportion of the loss, thus the greater the power-to-weight ratio.
