Oct 18, 2017 · Learn about sensorless brushless DC motor controllers, some example ICs, and some disadvantages of using such motors. A Quick Review of Brushed and Brushless DC Motors. Brushless DC (BLDC) motors have become extremely popular over their predecessor, the brushed DC motor (see figure below). As the name implies, "brushed" DC motors use brushes ...

According to the company, the DRV8312-C2-KIT (Figure 6) – based around the DRV8312 PWM motor driver – is a sensorless field-oriented control (FOC) and sensor/sensorless trapezoidal commutation platform that speeds development for quicker time to market. Applications include sub-50-V and 7 A brushless motors for driving medical pumps, gates ... Sep 19, 2016 · DTC is “Direct Torque Control,” a method used by ABB in their high-performance drives. “Vector” control is a generic term, while “DTC” is specific in how the “vector control” is performed.
FOC is more smooth and quite but less top speed and more low end torque. And FOC Sensored is basically the same as FOC but uses hall sensors in the motors? I'm not sure what these sensors do and according to DIYeboards they recommend FOC sensored. (for their motors atleast). PMSM field oriented control 3-phase Sensorless Single-Shunt Current-Sensing PMSM Motor Control Kit with MagniV MC9S12ZVM Application Notes Rev. 0 08/2016 NXP Semiconductors 7 3.3.1 DC-link current sensing Since the only current being measured is the DC-bus current, stator phase currents must be reconstructed

Speed sensor-based FOC is useful for avoiding control inaccuracies, which may arise in sensorless control due to variation in physical parameters of the motor, which happens because of temperature variation and aging. The FOC consists of controlling the stator currents represented by a vector. This control is based on projections that transform a three phase time and speed dependent system into a two coordinate (d and q coordinates) time invariant system. These projections lead to a structure similar to that of a DC machine control. With the FOC implementation you don't have to move them at all. This is because any current vector can be produced with FOC (as opposed to six 60 degree spaced fixed vectors with bldc) and the sensors just work like a low resolution absolute encoder.
