Brushless Motor Cooker Hoods
Energy saving Cooker Hoods with Brushless Motors
Brushless Energy Saving Cooker Hood Motors reduces noise up to 3dB(A) and increase hood efficiency by 30% even in the presence of a long stretch of ducting. So even the fastest extractor hoods stay quieter across all power levels.
The Brushless Motor guarantees considerable energy saving coupled with high extraction efficiency. They consume 85% less than conventional electric motors at low-medium speeds (in kW/h), and 35% less at high speeds. They are also the most silent-running motors on the market today and guarantee stable performance under all operating conditions. The motor also makes the extraction more precise in speed and are more durable than a traditional brush motor.
Generally, the efficiency of brushed motors is limited within the range of 75% to 80%, Brushless motors are capable of up to 90% efficiency.
The sound and heat produced by a brushed motor essentially represent power losses from the device, taking energy away from the rotor. In brushless motors, the amounts of sound and heat produced are greatly reduced, resulting in significantly higher efficiency. There is still some energy loss due to air friction as the rotor rapidly rotates, but this is minimal.
Quieter Motor Operation
Friction and electrical arcing between brushes and commutator plates in brushed motors produce substantial motor noise. In brushless motors, the job of commutation is carried out by an electronic circuit, resulting in much quieter operation at a lower pitch of sound.
Although the rapid rotation of the rotor still creates the characteristic “whirring” sound, it is still a huge improvement over traditional brushed motors.
Better Power to Weight Ratio
Fewer mechanical components mean brushless motors have lower mass than brushed motors. The result: brushless motors offer a better power-to-weight and torque-to-weight ratio than brushed motors.
Longer Life Motor
The brushes in brushed motors are gradually worn away with use since they are in constant contact with the. Brushless motors do not face this problem, which drastically increases the life span of the motor.
