2. DC motor - Wikipedia

   en.wikipedia.org/wiki/DC_motor

   A compound DC motor connects the armature and fields windings in a shunt and a series combination to give it characteristics of both a shunt and a series DC motor. [5] This motor is used when both a high starting torque and good speed regulation is needed. The motor can be connected in two arrangements: cumulatively or differentially.

3. Worm drive - Wikipedia

   en.wikipedia.org/wiki/Worm_drive

   A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear). Its main purpose is to translate the motion of two perpendicular axes or to translate circular motion to linear motion (example: band type hose clamp ).The two elements are also ...

4. Linear actuator - Wikipedia

   en.wikipedia.org/wiki/Linear_actuator

   These include dc brush, dc brushless, stepper, or in some cases, even induction motors. It all depends on the application requirements and the loads the actuator is designed to move. For example, a linear actuator using an integral horsepower AC induction motor driving a lead screw can be used to operate a large valve in a refinery.

5. Slewing drive - Wikipedia

   en.wikipedia.org/wiki/Slewing_drive

   The slewing drive is a modernized take on the worm drive mechanism, which dates back many centuries and was widely used during the Renaissance Era. Pappus of Alexandria (3rd century AD), a Greek mathematician, is credited with an early version of the endless screw, which would later evolve into the worm drive. [1]

7. Electric motor - Wikipedia

   en.wikipedia.org/wiki/Electric_motor

   A miniature coreless motor. The coreless or ironless DC motor is a specialized permanent magnet DC motor. [74] Optimized for rapid acceleration, the rotor is constructed without an iron core. The rotor can take the form of a winding-filled cylinder, or a self-supporting structure comprising only wire and bonding material.
