EC Motor Technology
Smarter motor.
Smarter motor.
Less energy. More control.
Electronically commutated (EC) motors combine DC brushless efficiency with AC supply convenience. Speed is modulated by a built-in inverter — no external VFD required, no additional panel space, no extra wiring.
Direct BAS integration over 0–10V or Modbus RTU. Onboard potentiometer for standalone operation.
