2. Motor constants - Wikipedia

   en.wikipedia.org/wiki/Motor_constants

   is the motor constant [1] (sometimes, motor size constant).In SI units, the motor constant is expressed in newton metres per square root watt (/): = where is the motor torque (SI unit: newton–metre)

3. Brushless DC electric motor - Wikipedia

   en.wikipedia.org/wiki/Brushless_DC_electric_motor

   A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.

4. Vector control (motor) - Wikipedia

   en.wikipedia.org/wiki/Vector_control_(motor)

   In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...

5. Hall effect sensor - Wikipedia

   en.wikipedia.org/wiki/Hall_effect_sensor

   Some types of brushless DC electric motors use Hall effect sensors to detect the position of the rotor and feed that information to the motor controller. This allows for more precise motor control. Hall sensors in 3 or 4-pin brushless DC motors sense the position of the rotor and to switch the transistors in the right sequence. [25]

7. Servo control - Wikipedia

   en.wikipedia.org/wiki/Servo_control

   Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...
