A motor cover arrangement for covering a cooling fan of a motor enclosed in a motor case, wherein the motor cover arrangement includes a cooling fan cover and an air intake hood. The cooling fan cover has an open outlet end mounted on the motor case and an inlet end extended from the motor case to define a fan cavity to dispose the cooling fan therein and an air inlet opening in front of the cooling fan. The outlet end of the cooling fan cover defines an air discharge slot between the outlet end and the motor case to communicate with the air inlet opening. The air intake hood includes a base shell integrally covering the air inlet opening of the cooling fan cover and an air intake shell extended from the base shell to a side portion of the cooling fan cover to provide an air intake window so as to form an air intake passage between the air intake window positioned at the side portion of the cooling fan cover and the air inlet opening of the cooling fan cover. Thereby, fresh air can be sucked by the rotating cooling fan from outside via the air intake window, the air intake passage and the air inlet opening to cool down the motor and be discharged through the air discharge slot, so as to increase both the air sucking effect and cooling effect.
