摘要：
A compact gear reducer electric motor assembly with an internal brake disclosed and claimed wherein a high speed electric motor is interconnected with a gear reducer having substantial gear reduction. The assembly includes a spindle, a brake mounted substantially within said high speed electric motor and operable against a spring biasing said brake into engagement with ground. The brake is electrically actuated to permit transmission of energy to the gear reducer. The gear reducer includes an input, intermediate and output planetary stages. The input and intermediate stages residing within the spindle, and, the output planetary stage drives an output ring gear, Releasing means for releasing the output ring gear from the brake allowing rotation thereof.
