A dryer tumble drying articles includes a drum including a cavity configured to hold articles to be dried, a first motor drivingly coupled to the drum to rotate the drum, a heat source in flow communication with the cavity, and a variable speed motor drivingly coupled to a blower positioned to deliver heated air from the heat source to the cavity.

A method for brazing end rings to rotor bars for a squirrel cage rotor assembly comprises assembling the rotor in a brazing fixture with a braze shim between the rotor bars and the end rings; preheating the rotor and brazing fixture to a temperature that is below the aged temperature of the rotor bars and end rings and which is sufficiently high so that the difference in thermal expansion of the rotor bars and brazing fixture applies a predetermined amount of pressure on the brazing joint such that after the joint is brazed and has cooled, a braze filler having a predetermined thickness inches will bond the rotor bar end faces to the end ring, and brazing each joint to bond the rotor bar end faces to the end ring. A braze fixture for maintaining a predetermined pressure on a squirrel cage rotor assembly during the process of brazing rotor bars to end rings to form a brazed joint, which rotor assembly includes rotor bars disposed in a rotor core and having their ends positioned on braze shims on end rings, comprises positioning means for positioning the rotor assembly in the apparatus; pressure means for applying a predetermined amount of pressure on the end rings, rotor bars and braze shims of the rotor assembly so that when the ends of the rotor bars, braze shims and end rings are brazed to form a joint, the resulting brazed joint has a predetermined thickness.

Irregularities in the outer surface of a commutator are identified and measured while the commutator is in the motor by removing a brush from its brush holder, and securing a jig in the brush holder. The jig has a sensor which generates electrical signals in response to movement of a profiling foot at an end of the sensor. The sensor is adjusted so that the profiling foot touches the commutator surface, and the commutator is then rotated at least one full revolution. By measuring movement of the profiling foot as the commutator turns, as observed through the output signals of the sensor, irregularities in the commutator surface can be identified and measured. The output signals of the sensor can be recorded or otherwise stored for analysis. The profiling foot is pivoted so that it rests flat against the commutator contacts, even if the brush holder is not properly aligned with the commutator.
