Abstract
A material handling vehicle includes a cyclonic motor cooling system for a motor compartment that accommodates an ergonomically designed operator compartment. Together, the motor compartment and cyclonic motor cooling system include a generally cylindrical housing with a tangentially arranged cooling air injection port at a lower end and exhaust port at a radially and axially opposite end. An air blower directs cooling air into the compartment where a cyclonic cooling air flow and a vortex cooling flow is produced. The cyclonic air flow cools more effectively than conventional linear air flow while also reducing dust contamination and buildup of the motors in the motor compartment.
