Electronically Controlled Blowers and Fans Offer OEMs Benefits

Tuesday, June 23, 2015


KENT, OH – AMETEK’s Precision Motion Control Division, a leading innovator of programmable and controllable air-movement solutions, offers a range of electronically commutated brushless motors, fans and blowers that provide original equipment manufacturers (OEM’s) with the greatest design flexibility during the product development and the highest level of product control, efficiency and long life in application.

AMETEK Windjammer® and Nautilair ® blowers utilize Intelligen II ™ controller technology with custom embedded software that provides end users with the lowest cost of operation along with such functional benefits as noise reduction. Their full-wave commutating electronics enhances versatility by providing functional performance options, protection features, and increased customization potential.

The technical benefits of AMETEK’s motors, blowers and fans support OEMs and their customers with in-the-field, on the fly performance adjustments, real-time diagnostic readings, and other advantages. The various technical features of these motors, blowers and fans allow their use in many unique applications. Among their features are controllability and universal usage at varying power inputs (100-240 VAC) that allow their use in such high-reliability applications, such as medical equipment and high-performance business machines.

Functional controllability is especially useful for applications that derive efficiency and operational improvements through variable speed performance, whether linear, non-linear, or step function operation. On-board signal level controllability allows end users to vary speed (virtually 0 to 100% variation) without any adjustments from the main input power supply.

The ability to “dial in” a specific operating point in a “real-time, on-demand” environment eliminates wasteful energy costs associated with over performance. By permitting a series of discreet “step” speed levels, designers can tune product performance to very specific and unique design and operational requirements.

AMETEK blowers are fully programmable so end users do not need to develop their own “hard” control schemes, but can take advantage of a multi-wire input for specific operational functions, including closed loop speed control, maximum speed set, electric braking, current limit, over temperature, locked rotor and others. The blowers also are designed to operate at the highest possible aerodynamic efficiencies, lowering their cost of operation and making them better suited for energy efficient or battery operated systems. All are powered by AMETEK’s highly reliable brushless DC 12 or 24 motors, which now feature a tachometer output signal as a standard option.

Electronic motor/blower controllers can be designed to accept continuously variable input voltage levels, specifically 83VAC through 264VAC (versus dedicated fixed 120V, 240V and other inputs), while maintaining similar product performance across the input range (see Figure 2). Universal Drive, or UD, provides OEMs with the advantage of using the same model number for all domestic and international products, eliminating the need to procure additional models, allowing for maximum usage flexibility worldwide, freeing product developers to focus on design improvements and other features.

Along with Windjammer® and Nautilair® variable-speed brushless blowers, AMETEK PMC brands include MICROjammer® variable-speed brushless blowers; ROTRON® regenerative blowers, transportation blowers, motors, pumps and fans; Haydon Kerk® linear actuators, rails, guides and splines, drives and motors; variable-speed brushless blowers; Pittman® brush and brushless motors, gearboxes, encoders, drives, brakes; and Dunkermotoren™ brush and brushless motors, gearboxes, controllers, linear systems and venetian blind drives.
