Electrically Commutated Motors Savings Tips    • Electrically
commutated motor (ECMs) are excellent devices for the energy-
conscious individual wanting to save on both energy consumption
and energy costs.   • They do not require airflow inside the
motor for cooling purposes due to the electric motor’s overall
construction.   • The entire assembly that is not affected by
centrifugal forces is a distinct advantage of this type of
design.   • ECMs are more efficient at converting electrical
energy into mechanical force, an advantage derived from the
absence of brushes.   • These motors do not have any losses due
to friction or electricity. This is more evident when an ECM
performs at low loads or no loads compared to brushed DC motors.
• It should be noted when the mechanical load is high, both
brushed and brushless DC motors operate at virtually the same
efficiency level.   • Overall, the ECM tends to be more
efficient than its industry counterparts. Compared to brushed DC
motors, the cost of installing and i
