Abstract: Apparatus features a microcontroller configured to: receive signaling containing information about a measured change of a magnetic field created by a magnetic circuit driving a motor; and determine corresponding signaling containing information about the speed of rotation of the motor, based upon the signaling received. The microcontroller provides control signaling containing information to control the operation of the motor, including where the motor control is used to control the flow of fluids from a pump. A Hall Effect Sensor is used to sense the magnetic flux and provide the signaling in the form of a feedback signal for implementing motor control. The motor housing has a slot, the Hall Effect sensor is mounted external the motor housing over the slot, and a ferromagnetic bridge is arranged over the Hall Effect sensor to close the magnetic circuit and cause more flux to go through the Hall Effect sensor.
