1.1.25 What are the advantages of permanently excited DC motors?

Advantages:

-          High efficiency
-          Small design with high power
-          High overload capacity for short periods
-          Stable speed
-          High starting torque
-          Lower heating, thus increase of duty cycle
-          Favourable price
-          Well suited for low voltages
-          High performance at low speed
-          Very high torque possible with small installation space
-          Simple construction of the motor
