Velocity controller

Helps minimize motor size

A sensorless velocity controller reportedly boosts the efficiency of open-loop, ironless-core, brushless motor applications. According to reports, the TG2601 vControl minimizes high-current ripple by operating at high frequency. This unit commutates the motor without the need for position sensors. Motors operate as a commutated brushless entity in a velocity-mode with an inner current loop.
