DC motors
* Series-wound DC motors: High starting torque, low speed at high load, used in applications such as power tools and automobile starters.
* Shunt-wound DC motors: Constant speed with varying load, used in applications such as fans and pumps.
* Series-Parallel DC Motors: A combination of series and shunt excitation characteristics, used in applications requiring both high starting torque and constant speed.
AC motors
*Single-phase AC motors: Small size, low cost, used in applications such as fans and home appliances.
* Multiphase AC motors: High efficiency, high starting torque, used in applications such as industrial machines and pumps.
* Induction motors: Require no starting capacitor, have a simple design, and are used in applications such as conveyors and compressors.
* Synchronous motors: Constant speed, high efficiency, used in applications such as generators and clocks.
Special purpose engines
* Stepper motors: Precise control of position and speed, used in devices such as printers and medical equipment.
* Servo motors: High precision and torque, used in applications such as robotics and control systems.
* Linear Motors: Motion in a straight line, used in applications such as magnetic levitation trains and automated production lines.
* Brushless motors: High efficiency, maintenance free, used in applications such as drones and electric vehicles.
