Understanding back EMF measurement in brushed DC motors

WebMar 4, 2024 · Brushless DC motors have several differences from brushed DC motors. They do not require physical contact to switch coil states, and they use permanent magnets. In brushless DC motors, the principal driving force behind the motor works in the same way as a brushed motor, but there is no physical contact to switch the states of the armature. The following graphics illustrate a simple, two-pole, brushed, DC motor. When a current passes through the coil wound around a soft iron core situated inside an external magnetic field, the side of the positive pole is acted upon by an upwards force, while the other side is acted upon by a downward force.
