3phase Field Oriented Control (FOC) STMicroelectronics

Replacing the sensors entirely in an FOC motor controller reduces the cost and increases the reliability of an AC induction motor, but also increases the complexity and cost of the controller. To replace the sensor, the information on the rotor speed is extracted from the voltages and currents in the stator windings via the motor terminals. This is then fed back into the current control of the ...


Tricking a motion detector with a camera? : hacking

I''m at a coworking space that at night have the lights of a room triggered by a motion detector (there are 3 of them in the room), the issue is that as I''m studying I''m not moving from the position and lights keep turning off , as soon as I move a bit the chair the lights turn on again. I can''t stand this to be honest , either turn them on or turn them off , but don''t play around with me as ...
