Abstract

The blower is driven by a DC motor (1) within a housing (4) having air ducts running to back (21"). Air scoops (8) on the front of the motor housing and vents (7) in a separate enclosure (10) for the control resistors are in the slipstream of the fan blades (3). Dropping resistors (15', 15") wound on formers (16', 16") are mounted on a carrier plate (11) which ha a terminal block fitted through a hole in the rear wall of the housing for connection to the control and supply wiring. A short cable connects the resistor block to the motor via a duct (20) between the two housings. This duct also aids the circulation of air around the resistors and the motor.
