Centrifugal Fan Driven by ECM NECI7215 B6V230A
Main Characteristics :
⚫ Motor Type: 3 Phase internal rotor brushless motor.
⚫ Control Driver Circuit: built-in circuit, sine wave drive (with lower noise and vibration, but the motor efficiency is also lower).
⚫ Hall Sensor: No.
⚫ Motor Rotation: In CW direction seeing from the wind wheel side.
⚫ Fixing of the Blower: By the 2-Ø5.5 through holes and 2-5.5 notches in the aluminum nozzle of the volute (see from the drawing).
Typical Applications :
This blower is mostly used for gas system water boiler, pellet stove, etc. It can also be used for other applications that need high speed blower.
Brief Introduction :
1. This is a Centrifugal Fan including an ECM (Brushless Motor), a set of volute, a centrifugal fan and a plastic air-inlet device.
2. The ECM (Electronically Commutated Motor) is a high efficiency programmable brushless DC motor utilizing a permanent magnet rotor and a built-in inverter.
3. DC motor is significantly more energy efficient than AC motor and much easier to control. The energy saving is upto 65% in average compared to shaded pole motor, or 35% compared to PSC motor.
4. The motor is of long lifetime, wide range of applications and speed regulations.
5. It’s generally available for products of low speed (generally less than 6000RPM).
6. It’s with large rotation inertia, simple structure & not accurate starting position.
Remarks:
This catalog listed just some typical models. The performances as above are just for reference only. We can adjust our motor specifications according to what the customer needs. OEM & ODM are both welcome.
