Esp8266 githubfor speed and torque changes, sophisticated control techniques, such as Field Oriented Control (FOC) are required. 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. Hobbywing AXE FOC Waterproof Sensored Brushless Combo with 1800kv motor. FOC (Field-oriented Control) for Super Linearity, High Torque & Extreme Silence Hobbywing sensor technology has changed the feel, performance, and overall tune-ability of the Axe ESC and Motor in ways some have never experienced.
" This is a NEW Genuine Castle Creations 1410 1Y 4-Pole 3800Kv 3.17mm Shaft Sensored Brushless Motor. SMARTSENSE™ uses the motors sensors to start the motor to provide smooth starts, excellent torque, and low-speed drivability.
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. 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. Sensored Motors uses the "Hall Effect" (named after Edwin Hall, an American Physics scientist) to detect the rotor (magnetic poles with different polarity) inside the motor and transmit the data to the ESC through a sensor wire. It allows the ESC to control the rotation and the speed of the motors precisely.
As a general rule, FOC requires EITHER of those sensors, but some can function without the external encoder. So the term "sensorless" is referring to the versions where there are no EXTERNAL sensors, i.e. there is no encoder required.
