Normal work detecting method for drum type motor

Abstract

The present invention provides a normal work detection process for a drum motor. The main device used comprises an electrical source supply part for supplying power, a signal input part and a driving part for driving a motor, wherein a control part connected with the signal input part is equipped therein with a current measurement part of currents flowing into the drum motor, to detect the normal work of the drum motor. The process comprise the following stages: setting stage: setting the drive current scope of a drum motor when the drum motor acts normally; drive stage: driving the drum motor; detection stage: detecting drive current of said drum motor; and judgement stage: judging whether the drum motor works normally. The present invention has the following positive effect: according to the information such as whether the electric motor rotates, abnormal states and rotative velocity which can be easily obtained from the current measurement values in accordance with the present invention, one can easily determine whether the electric motor works normally, with reduced cost of manufacture and improved satisfying degree of users.

Description

technical field [0001] The present invention relates to a drying machine, especially a method for detecting the normal operation of a drum motor by detecting the current generated when the drum motor is driven to determine whether the motor is rotating normally. Background technique [0002] As shown in Figs. 1a and 1b of a general motor rotation detection method of a dryer, a drum 1 is installed inside a casing (not shown) constituting the appearance of the dryer. The above-mentioned drum 1 is provided with openings on both sides in the horizontal direction, and a belt groove 2 around which a belt (not shown) is driven by another driving source is formed along the middle part of the outer surface. A plurality of partitions 6 are formed on the above-mentioned drum 1 to turn over the drying object inside the above-mentioned drying box 5 when rotating. [0003] A front head 7 and a rear head 9 are respectively arranged on the front end and the rear end of the above-mentioned ...

AI Technical Summary

Problems solved by technology

With the above constituent parts, the manufacturing cost is increased

Moreover, as mentioned above, there are many components for judging whether the drum motor is rotating or not, and there is still a problem that it cannot be judged whether the drum motor is rotating normally or not.
