WebThis gives several of the advantages of induction motors: no brushes or commutator means easier manufacture, no wear, no sparks, no ozone production and none of the energy loss associated with them. Below left is a schematic of an induction motor. (For photos of real induction motors and more details, see Induction motors.) Web26 jan. 2024 · The back-EMF is a voltage caused by the magnetic induction (Faraday-Lenz law of induction) that opposes the applied voltage and is proportional to the motor speed. See Figure 8, showing the motor when the PWM is ON, and when the PWM is OFF. ... Unlike brush dc motors, brushless dc motors do not have brushes.

Web26 apr. 2024 · Thus, Brushed DC motors have low efficiency and requires periodic maintenance. This creates a lot of friction, and friction equals heat (energy loss) and wear and tear. Brushless DC on the other hand are essentially frictionless and thus have really high efficiency, require zero maintenance and last longer than brushed DC motors.
