Abstract:
A motor drive assembly for a dual path electric powertrain of a machine is disclosed. The motor drive assembly may include a final drive assembly to engage a ground engaging element of the machine. The motor drive assembly may include an electric motor to provide torque to the final drive assembly. The motor drive assembly may include a planetary gear assembly mechanically coupled to a rotor shaft of the electric motor and an axle of the final drive assembly. The motor drive assembly may include a brake assembly to engage a component of the planetary gear assembly to retard the rotor shaft and the axle.
