Title:
HEAT GENERATING MOTOR AND WARM AIR AND WARM WATER GENERATOR USING SAME
Document Type and Number:
WIPO Patent Application WO/1990/004745
Kind Code:
A1
Abstract:
This invention relates to a heat generating motor adapted to generate power while intentionally converting the major part of electric power into heat, and a warm air and warm water generator using such a motor. In the motor according to the present invention, a ceramic-insulated electric wire is used as a stator winding or a coil block heating element which is used exclusively for the generation of heat, whereby the major part of the service power is safely converted into heat. When the quantity of service power is increased in a small-size motor for use in generating heat rather than power, vibration and a roaring noise occur due to the influence of magnetism. The motor according to the present invention is provided with a stator having a ceramic-insulated winding therearound and formed with a very small thickness, consisting of a non-ferrous material, such as aluminum or having a hollow stator core to prevent the occurrence of magnetic vibration and a roaring noise. Thus this motor enables the supply of large power to a small-size motor, which has been impossible heretofore.
