HOT ROLLER WITH A BUILT-IN MOTOR

A hot roller with a built-in motor in which the whole length thereof is shortened and the heat efficiency is improved. In the hot roller, a heater coil (10) is fixedly fitted onto a surface of a motor outer housing, and a motor rotor shaft (7) of the motor is connected to a hot roller rotary shaft (...

More Information
Summary:A hot roller with a built-in motor in which the whole length thereof is shortened and the heat efficiency is improved. In the hot roller, a heater coil (10) is fixedly fitted onto a surface of a motor outer housing, and a motor rotor shaft (7) of the motor is connected to a hot roller rotary shaft (12) of a hot roller rotor (11, 11A, 11B) formed so as to cover the heater coil (10). In this case, it is preferable that a ceramic bearing is used as a bearing (8a, 8b) of the motor rotor shaft (7) so as to perform oil-mist lubrication, and that heat pipes (15) are provided in the hot roller rotor (11, 11A, 11B).
