In the late 1800s, several inventors built the first working motors, which used direct current (DC) power After the invention of the induction motor, alternating current (AC) machines largely replaced DC machines in most applications However, DC motors still have many uses DC motor principles

Direct-Current Machine an electric rotating machine that converts mechanical energy to DC electrical energy (a generator), or vice versa (a motor) It is reversible—that is, the same machine can operate both as a generator and as a motor For example, traction motors of rolling stock and servomotors of high-power DC electric drives operate in this way

Direct-Current Machines • Direct-current (DC) machines are driven from a DC power supply although their construction is made rather complex by the fact that they need a commutator, which reverses the direction of currents and fluxes to produce a net torque • In a DC machine, the magnetizing current is DC Commutation is the
