The application discloses a motor assembly for a clothes dryer, comprising a rack, a double-shaft motor, a transmission mechanism, a retreat-stop mechanism, a ratchet switching mechanism, a multi-stage speed regulation mechanism and an output wheel. The first output end of the double-shaft motor is directly connected with a fan, and the second output end is connected with a driving wheel, a driven wheel and a conveying belt to form a first-stage speed reduction. The retreat-stop mechanism locks the driven wheel when the motor reverses, so that the conveying belt slips. The ratchet switching mechanism comprises a first ratchet component, a second ratchet component and a sleeve component. The slipping during the motor reversal drives a swing lever, and the sleeve is reversely rotated through the cooperation of ratchet teeth. The fixed and movable rotating ratchets of the second ratchet component are connected through spiral ladder clamping claws, so that rotation is converted into axial transition. The multi-stage speed regulation mechanism pushes a planetary gear carrier through a movable rotating ratchet, so that different levels of planetary gears are engaged with corresponding gear rings, multi-stage speed regulation is realized, and finally the output wheel is driven to rotate at variable speed. The application realizes automatic switching and multi-stage speed regulation through motor reversal, and improves the performance and energy efficiency of the clothes dryer.
