2. Servomotor - Wikipedia

   en.wikipedia.org/wiki/Servomotor

   A servomotor (or servo motor or simply servo) [1] is a rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system. [ 1 ] [ 2 ] It constitutes part of a servomechanism , and consists of a suitable motor coupled to a sensor for position feedback and a controller ...

3. Brushless DC electric motor - Wikipedia

   en.wikipedia.org/wiki/Brushless_DC_electric_motor

   Brushless DC motors are widely used as servomotors for machine tool servo drives. Servomotors are used for mechanical displacement, positioning or precision motion control. DC stepper motors can also be used as servomotors; however, since they are operated with open loop control , they typically exhibit torque pulsations.

4. Motor constants - Wikipedia

   en.wikipedia.org/wiki/Motor_constants

   The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in RPM) to the peak (not RMS) voltage on the wires connected to the coils (the back EMF). For example, an unloaded motor of K v {\displaystyle K_{\text{v}}} = 5,700 rpm/V supplied with 11.1 V will run at a nominal speed of 63,270 rpm (= 5,700 rpm/V ...

5. Servo drive - Wikipedia

   en.wikipedia.org/wiki/Servo_drive

   OEM servo drive from INGENIA installed on CNC router machine controlling a Faulhaber motor. Servo systems can be used in CNC machining, factory automation, and robotics, among other uses. Their main advantage over traditional DC or AC motors is the addition of motor feedback. This feedback can be used to detect unwanted motion, or to ensure the ...

6. Synchronous motor - Wikipedia

   en.wikipedia.org/wiki/Synchronous_motor

   A permanent magnet synchronous motor and reluctance motor requires a control system for operating (VFD or servo drive). There is a large number of control methods for synchronous machines, selected depending on the construction of the electric motor and the scope.
