Question:

What are the differences between: DC Drives Vs DC Machines (or DC Motors) & AC Drives Vs. AC Machines (Motors)?

What are the differences between: DC Drives Vs DC Machines (or DC Motors) AC Drives Vs. AC Machines (Motors) ?Why we add a word called drive ?thanks in advance

Answer:

Ac or dc motors are strictly devices that convert electrical into mechanical (normally rotational) energy. Ac or dc machines may be either motors or generators. Drives, of either type, are systems which, as well as motors, may also include control elements such as feedback devices, thyristors or frequency converters to provide the motors with appropriate voltage and/or frequency for the given task.
Dc is direct current meaning the electrical current is either -or+ and ac is alternating current which constantly switches from + to -
