Abstract
A concrete vibrator motor includes a motor assembly that provides actuation and a cage assembly that surrounds the motor assembly to shield it and provide one or more operator handles. The motor assembly includes a motor housing, a motor pod, and a plurality of brushes that are used to secure the motor pod within the motor housing. The cage assembly includes a pair of endcaps and handles arranged beneath the endcaps. The endcaps are configured to inhibit fluid ingression into the motor housing while permitting air circulation between the ambient environment outside of the motor housing and within the motor housing. Thus, the motor assembly may intake air into the motor housing and exhaust air therefrom without contamination from the ambient environment.
