この発明はエレベータ用モータの異常検出装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an abnormality detection device for an elevator motor.
エレベータの乗かとを駆動するモータは、その温度が上
昇すると絶縁物の劣化が生じるので、絶縁物の階級に応
じて許容温度が規定されている。When the temperature of the motor that drives the elevator seats increases, the insulator deteriorates, so the allowable temperature is defined depending on the class of the insulator.
しかし、許容温度以下で使用しても長時間使用な続ける
と、絶縁物が次第に劣化して巻線が層間短絡し、巻線が
異常に温度上昇し遂には焼抄するに至ることがある。However, if the wire is not used for a long time even if the wire is used at a temperature below the allowable temperature, the insulator gradually deteriorates and the winding wire becomes short-circuited between layers, and the winding wire becomes abnormally heated, which may eventually lead to paper burning.
このような事故を防ぐための方式が、実開昭５１−１１
５３４３号公報に開示されている。この提案されている
方式では、エレベータの乗かごを駆動するモータのコイ
ル内に温度センサを配設し。A method to prevent such accidents was developed in 1986.
It is disclosed in Japanese Patent No. 5343. In this proposed method, a temperature sensor is placed inside the coil of the motor that drives the elevator car.
この温度センサの検出温度が所定値に達するとモータの
電源を遮断するように構成されている。The motor is configured to shut off power when the temperature detected by the temperature sensor reaches a predetermined value.
モータが完全に短絡された状態になると、その巻線温度
は急激に上昇する、このため、許容の温１’に到達する
前にモータが異常であることを検出し、モータの電源を
遮断することが望ましい。When the motor is completely short-circuited, its winding temperature will rise rapidly, so it will detect that the motor is abnormal and cut off the power to the motor before it reaches the allowable temperature 1'. This is desirable.
しかし、従来提案されている方式では、設定温度が許容
温度の近傍に設けられるので、早めに電源を遮断するこ
とが出来ない。また、エレベータは一日の使用状態にほ
ぼ同一の傾向が存在する。However, in the conventionally proposed systems, the set temperature is set close to the allowable temperature, so it is not possible to shut off the power early. Furthermore, elevators tend to have almost the same usage status throughout the day.

常検出が出来る。従来提案されている方式では、このよ
うな温度の異常検出を行なうことは出来ない。Therefore, there is a tendency for the temperature of the motor to change depending on the change in usage conditions on the day of the day, resulting in a temperature change as well. If an abnormality in the temperature of the motor is detected by referring to this change trend in the temperature of the motor, it is possible to detect an abnormality in temperature more accurately. Conventionally proposed methods cannot detect such temperature abnormalities.

ることにある。This invention was made in view of the current state of conventionally proposed abnormality detection devices for elevator motors, and its purpose is to refer to the temperature of the motor during the past driving state of the elevator,
To provide an abnormality detection device for an elevator motor capable of detecting an abnormal temperature at a temperature considerably lower than an allowable temperature and quickly detecting an abnormal state of the motor at a high wtlf.
