The following are grabbed from this application note:

In most motor control systems, several sensors are used to provide feedback information on the motor. These sensors are used in the control loop and to improve the reliability by detecting fault conditions that may damage the motor. As an example, Figure 1 provides a block diagram of a DC motor control system to show the sensor feedback provided for a typical motor control.

In addition, this application note explains info about hall effect tachometers, transformers, back emf control, shunt measurements, hall effect sensors, block diagram, measurement circuit, comparator circuit, motor, differential amplifier, system, filter, noise, protection, sensing transformers, circuits, pcb, output signal, and control method.
