Blowers for air circulation in bakers' ovens face the problem that the blower motor, as a result of heating up itself and as a result of heat being conducted from the heated baker's oven, is under a very high thermal load. The object of the invention is to deal with the problem of, on the one hand, providing effective removal of the operational heat of the motor and, on the other hand, to prevent any adverse effects due to the oven heat applied from outside. This object is achieved according to the invention by the blower motor being traversed by one or more axial and/or axially parallel flow ducts, and by flow guiding means being provided on the drive shaft, which keep the external heat away from the motor. <IMAGE>
