LH Motor Is Your Expert Manufacturing for Vacuum Motors

LH has 2 types: Brushed Bypass Motors and Brushed Thru-Flow Motors

LH Brushed Bypass Motors

LH manufactures a wide range of Bypass motors for the commercial floor care, central vacuum, commercial and industrial applications. In bypass motors, the working air is independent from the cooling air. A separate fan is used to direct cooling air over the armature and field. Cooling air is typically made available through an 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 working air does not travel across the motor at all, this style of motor is a dependable choice for wet pickup applications such as scrubbers and carpet extraction.

LH Brushed Thru-Flow Motors

LH manufactures a wide range of thru-flow motors for the commercial floor care, central vacuum, commercial and industrial applications. In thru-flow motors, the working air travels through the fan system and is discharged directly over the motor windings as it exits, so the working air also provides the cooling air for the motor. Typical applications are mostly in dry vacuum conditions since the working air is also cooling the motor.

Brushed Bypass Motors and Thru-Flow motors are available in single and multiple stages. the stages are used to create more pressure if used as a blower or more lift if used as a vacuum. As single stage motors typically have the highest air flow and 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 addition fans (rotating and stationary) through which the air must pass.
