Bypass Motors

Lamb® Bypass Motors

In bypass motors, the working air is independent from the cooling air. A separate fan is used to direct cooling air over the windings (armature and field).

Peripheral and tangential blowers are the two subtypes of bypass motors, both featuring a round-cylinder morphology to accommodate the rotating circular fan.

However, tangential bypass blowers include a horn to force air to exit the blower at a right angle to the air-inlet direction. The horn provides a convenient way to capture and direct the pressurized exhaust air.

Instead of a horn for air discharge, peripheral bypass blowers include small louvres around the side of the cylinder. Air exits as if it is leaking out of the cylinder instead of being directed out.

The motors come in single or multiple stages. Additional fan stages increase vacuum capability but reduce air flow due to increased impedance.

Bison® produces various bypass motors for vacuum and blower applications, including floor cleaning equipment, animal grooming dryers, sprayers, foggers and more.
