    • DC machines can develop rated torque at all speeds from standstill (locked-rotor) to rated speed. DC machines are easier to analyze than their AC counterparts, 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.
