Recycling back emf
Webb1 maj 2024 · All you need to do is measure the terminal voltage and input current then use the formula for Back EMF. At no load the current will be less than the simple Applied Voltage divided by Measured Resistance would suggest. This is because the windings are generating a voltage internal to the motor which is the Back EMF. WebbTo observe the effect of back-EMF of a motor, one can perform this simple exercise: with an incandescent light on, cause a large motor such as a drill press, saw, air conditioner compressor, or vacuum cleaner to start. The light may dim briefly as the motor starts.
