Motor types: Wound-field dc motors are usually classified by shunt-wound, series-wound, and compound-wound. In addition to these, permanent-magnet and brushless types are also available, normally as fractional-horsepower motors. Motors may be further classified for intermittent or continuous duty. Continuous-duty motors can run without an off period.
For Industrial applications use direct current(D.C) motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of rotation. Continuous operation of dc motors is commonly available over a speed range of 8:1. Infinite range (smooth control down to zero speed) for short durations or reduced load is also common.
Dc motors are often applied where they momentarily deliver three or more times their rated torque. In emergency situations, dc motors can supply over five times rated torque without stalling (power supply permitting).
Dynamic braking (motor-generated energy is fed to a resistor grid) or regenerative braking (motor-generated energy is fed back into the dc supply) can be obtained with dc motors on applications requiring quick stops, thus eliminating the need for, or reducing the size of a mechanical brake.
Dc motor speed can be controlled smoothly down to zero, immediately followed by acceleration in the opposite direction -- without power circuit switching. And dc motors respond quickly to changes in control signals due to their high ratio of torque to inertia.
