In order for conventional digital cameras to minimize noise levels while shooting video, such measures as expensive low noise level motors, motors with limited speed and filters that prevent the passage of strong motor noise frequencies were adopted.
Among other features, all versions of the ultra-quiet CT 200h come with a system that generates an artificial motor noise to warn pedestrians when the vehicles come close to them.
The performance and functionality of the drive module is based on the ultimate in motor control technology as provided by the Direct Torque Control (DTC) with enhanced features such as improved performance close to zero speed without encoder, low motor noise mode, higher output frequency and improved motor identification at stand still.
And the Forest Service is being inconsistent because it still allows motor noise from such sources as generators in campgrounds near Waldo Lake (the fact that noisy equipment is permitted in a few places does not mean it must be permitted everywhere).
Several models also can be mounted in the countertop so the motor is below the counter, lessening the motor noise even more.
These advantages include consistent airflow over a range of downstream static pressures, gradual ramp-up to setpoint flow rate at start-up, longer motor life, and less motor noise.
