Sensored 3-Phase BLDC Motor Control Using MSP430
نویسندگان
چکیده
Brushless DC (BLDC) motors are electronically commutated motors that offer many advantages over brushed DC motors and, therefore, are becoming very popular industrially and commercially. This application report discusses a sensored 3-phase BLDC motor control solution using MSP430TM as the motor controller. Hall sensors are used to detect the rotor position and close the commutation loop. Both open loop and closed-loop control implementations are discussed. Project collateral and source code discussed in this application report can be downloaded from the following URL: http://www.ti.com/lit/zip/slaa503.

Sensored Single-Phase BLDC Motor Driver Using PIC16F1613
This application note describes a driver solution for single winding single-phase BLDC, based on the PIC16F1613 microcontroller. The driver exploits two feedback loops: the inner loop, which is responsible for the commutation control, and the outer loop which is responsible for the speed control. The speed of the motor is referenced to an external analog voltage. Fault detection can be sensed d...
