BLDC Motor Control Development Tools. Key Characteristics of the BLDC Motor. The Brushless DC Motor does not operate directly off a DC voltage source. The brushless DC motor has a rotor with permanent magnets, a stator with windings and commutation that is performed electronically. Typically three Hall sensors are used to detect the rotor position and commutation is performed based on Hall sensor inputs. Description.

Explore Microchips brushless DC motor solutions with 8bit MCU,16bit DSC, 3phase FET drivers, and fully intergrated BLDC driver solutions. Motor driver ICs for automotive DC motors, stepper motors and brushless dc motors. The motor is driven by rectangular or trapezoidal voltage strokes coupled with the given rotor position. The voltage strokes must be properly applied between the phases, so that the angle between the stator flux and the rotor flux is kept close to 9. The position sensor required for the commutation can be very simple, since only six pulses per revolution in a three phase machine are required. Typically, the position feedback is comprised using three Hall effect sensors aligned with the back EMF of the motor. In sensorless control, back EMF zero crossing is used for commutation.
