Permanent Magnet Motors Explained

  • What is an Electronically Commutated EC Motor

    Sep 11, 2019· An electronically commutated (EC) motor is designed to run on an alternating current (AC) power supply, but it in fact bears a closer resemblance to a direct current (DC) motor. It is essentially a permanent magnet, brushless DC motor that incorporates on-board electronics.
