How Crank Flashlights Work
A crank flashlight basically works by hand cranking a permanent magnet motor, which generates electricity for illuminating the attached LEDs. Motor Becomes a Generator Normally, a permanent magnet motor is used for executing a rotational movement by applying a DC potential across its specified supply terminals. However we also know that the same motor can […]
Universal ESC for BLDC motors
In this post we discuss a universal ESC circuit or an electronic speed controller circuit which can be universally applied for controlling any type 3 phase BLDC motor. What is an ESC An ESC or electronic speed controller is an electronic circuit which is normally used for operating and controlling a BLDC 3-phase motor. BLDC […]
