Brushless Blowers include full-wave electronic controller.
Press Release Summary:
April 14, 2014 - Powered by 1.7 in. brushless 12 or 24 Vdc motor, MICROjammer® Series is available in sizes from 3.0–5.1 in., each providing unique aerodynamic operating characteristics for custom fit. Variable-speed blowers deliver up to 50 in. w.c. of static pressure and achieve airflow levels of 26 cfm. Allowing virtually 0-100% total speed variation, full-wave commutating electronics optimize blowers by providing protection features, functional options such as tachometer input, and customization potential.

AMETEK Precision Motion Control Microjammer Blowers Upgraded to Full-Wave Electronic Controller
Press release date: April 10, 2014
The full-wave commutating electronics package enhances the versatility of the MICROjammer blower family well beyond its previous half-wave version by providing more protection features, functional options (including a tachometer output), and increased customization potential. Previously, all of these benefits were only allowable through implementation of a costly, space-consuming external drive.
Being fully programmable, end users no longer need to develop their own “hard” control schemes but can now take advantage of an AMETEK 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 upgraded controller also allows a greater range of speed control (virtually 0-100% total speed variation is achievable). End users will no longer need to vary input voltage to achieve specific operating characteristics, but instead, they can take full advantage of the on-board signal-level controllability.
Along with these benefits, upgraded MICROjammer blowers offer greater operating efficiency, lowering their cost of usage and making them better suited for energy efficient or “green” applications. These units can now deliver up to 50 inches (water column) of static pressure and achieve airflow levels of 26 cubic feet per minute.
By continuing to provide AMETEK’s low-inertia, high-dynamic response characteristics, MICROjammer blowers are the industry choice for a variety of high-end blower applications such as business machine, computer, medical, printing equipment, and others. Blower package sizes vary from 3.0 inches to 5.1 inches, each providing unique aerodynamic operating characteristics allowing for a custom fit. All units continue to be powered by AMETEK’s industry reliable 1.7-inch brushless 12 or 24 VDC motor.
Along with MICROjammer® variable-speed brushless blowers, AMETEK PMC brands include Windjammer® variable-speed brushless blowers; Nautilair® variable-speed brushless blowers; ROTRON® regenerative blowers, transportation blowers, motors, pumps and fans; Haydon Kerk® linear actuators, rails, guides & splines, drives and motors; Pittman® brush and brushless motors, gearboxes, encoders, drives, brakes; and Dunkermotoren™ brush and brushless motors, gearboxes, controllers, linear systems and venetian blind drives.
