1.DC motors are direct current motors while ac motors are alternating current
motors.
2.DC motors generally characterize a continual and standard current flow
while AC motors are used in variant situations irrespective of the quality of the
current flow.
3. DC motors are single phase motors whereas AC motors are both 1 and 3
phase.
4.DC motors are self starting whereas AC motors require effective starting
equipment.
5.Direct current or DC electric motors work for situations where speed needs to
be controlled.
