Abstract
An electric drive module and an electric drive equipment are provided, the electric drive module comprises a housing, a force output assembly, a flexible gear, a rotor, a stator, a wave generator, and a cooling pipe, the stator is configured to drive the rotor to rotate relative to the housing, when the rotor rotates, the wave generator drives the flexible gear to deform to drive the rigid gear to rotate, at least part of the cooling pipe is received in and closes to the stator. The electric drive module is compact and space saving, the flexible gear is secured to the housing, the rotation of the rigid gear driven by the deformation of the flexible outputs power, which is low rotational inertia and decreases vibration, the cooling pipe arranged in the stator can directly dissipate heat from the stator with high heat dissipation efficiency.
