Brushed motors wear out relatively rapidly. Yet, the industrial robot must be designed for lifetime use. Therefore, AC brushless or DC brushless motors seem like the better design choice.
The major difference between AC brushless and DC brushless motors is that the former has a sinusoidal back emf and the latter has a rectangular/trapezoidal back emf. For simplicity of motor control, the brushless DC motor seems to be the optimal choice for the industrial robot.
