The various advantages of ECM motor
The various advantages of the EC motor resulting from the use of state-of-the-art electronics make it the recommended choice for both air and drive engineering:
1)High Efficiency resulting in energy saving and fast amortization
2)Continuously variable speed control by analog or digital input 0-10V/PWM
3)Simple speed control or more complex closed-loop control options can be integrated at competitive cost
4)Cross linked bad bus-connected installations are easy to achieve
5)High performance density, i.e. compact design
6)Temperature, CO2, humidity and airflow-dependent speed control options (intelligent fans)
7)Minimal heat load due to extremely high efficiency.
8)Speed and/or air flow monitoring
9)Longer life resulting from lower rise temperatures, maintenance-free ball bearing and soft-start.
11)Built-in protective systems ( e.g. Looked rotor protection, reverse polarity protection)
12)Easy connection : No complicated wiring and set-up with a frequency controller..
13)Can be operated directly from AC mains supply, or from DC.
