Updated June 2020. || Brushless dc (BLDC) motors are DC motors that use magnets instead of brushes and a commutator for commutation. The benefit to that is they don’t suffer from brush wear … but the drawback is that they need electronic current-phase commutation. In short, brushless DC motors work like shunt-wound motors, but field flux comes from […]
Motors
What are dc motors and how do definitions vary? Technical summary for engineers
Updated May 2019. || Dc motors are motion components that take electrical power in the form of direct current (or some manipulated form of direct current) and convert it into mechanical rotation. The motors do this through the use of magnetic fields that arise from the electric currents to spur rotation of a rotor fixed […]
