    Construction: BLDC motors have many similarities to AC induction motors and brushed DC motors in terms of construction and working principles respectively. Like all other motors, BLDC motors also have a rotor and a motors can be constructed in different physical configurations. Depending on the stator windings, these can be configured as singlephase, twophase, or threephase ...

    • DC machines can develop rated torque at all speeds from standstill (lockedrotor) 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. • DC motors are used in a wide variety of industrial drives ...
