Bypass Motors: Tangential and Peripheral
AMETEK Floorecare & Specialty Motors manufactures a wide range of Bypass motors for the commercial floorcare, central vacuum, commercial and industrial applications. In Bypass motors the work is independant from the cooling air.  A separate fan is used to direct cooling air over the armature and field.  Manufacturers should ensure that the cooling air does not mix with the vacuum or blower air.  Cooling air is typically mad available through a egress in the equipment housing.  Bypass motors come in two configurations: Peripheral Bypass and Tangential Bypass.  The method a manufacturer chooses depends on the method of mounting and air ducting geometry.  Because the work air does not travel across the motor at all, this style motor is a dependable choice for wet pickup applications such ar scrubbers and carpet extraction.

Bypass motors are available in single and mutltiple stages. The stages are used to create more pressure if used as a blower or more lift if used as a vacuum. Single stage motors typically have the highest air flow/air watts while the lowest vacuum levels. Adding fan stages increases the vacuum capability of the unit but reduces the air flow. This is because of increased impedance to air flow through the system, the result of additional fans (rotating and stationary) through which the air must pass.
