5-DC Motors

4. Characteristics

The DC machine is characterized by:

  • The nominal power of operation;

  • The armature voltage;

  • The speed of rotation;

  • The Torqus;

  • The power supply of the inductive circuit.

Characteristics of the operation according to the power supply of the inductor:

Speed/Current

Torque/Current

Torque/Speed

Note: When the inductive flux tends to 0, the velocity tends to infinity. It's the runaway
