Definitions:

Servomotors

Specialized motors equipped with a feedback mechanism for precise control of angular or linear position, speed, and acceleration.

Permanent Magnet Motors

Electric motors that utilize permanent magnets to generate the magnetic field within the motor, rather than an electrical coil.

Field-wound Motors

Electric motors where the magnetic field is generated by winding wire around a core to create electromagnets, typically adjustable for speed control.

Efficiency

The ratio of useful output of a system to its total input, often expressed as a percentage, indicating how well the system converts input energy into output work or desired form of energy.
