The utility model relates to the technical field of motors, and provides a friction force self-locking motor assembly and a lifting device.The friction force self-locking motor assembly comprises a shell and a motor, the motor is arranged in the shell in a sleeved mode, an output shaft of the motor is connected with a one-way bearing in a sleeved mode, and the outer ring of the one-way bearing is in interference fit with the shell. According to the friction force self-locking motor assembly, the arrangement of the one-way bearing and the interference friction connection between the one-way bearing and the shell can provide enough self-locking force for the motor, and the production cost of the friction force self-locking motor assembly is saved; furthermore, due to the arrangement of the one-way bearing, large friction force does not need to be overcome when power is output, the output power consumption of the motor is saved, and the use cost is reduced. 本申请涉及电机技术领域，提供了一种摩擦力自锁电机组件和升降装置，其中摩擦力自锁电机组件，包括壳体和电机，所述壳
