Parameters relating to rotation of a motor (2) measured every constant time are acquired and the moving average of each constant interval of the parameters is calculated. The calculated moving averages are input to a training model trained so as to output a temperature of magnets attached to a rotor (7) of the motor (2) when the moving averages of the parameters relating to rotation of the motor (2) are input, and an estimated value of the magnet temperature output from the model is acquired. Next, the acquired estimated value of the magnet temperature is output.

A thermometer for a rotisserie having a temperature sensor for measuring a temperature of food in a cookbox, a base station for receiving the measured temperature of the food from the temperature sensor, and a shaft body having a first portion for supporting the base station exterior to the cookbox and a second portion receivable within the cookbox. The shaft body defines a channel passing between the first portion and the second portion for receiving a temperature sensor wire therein such that the temperature sensor in the cookbox can be electrically coupled to the base station.

A system and method includes a seed roll of a saw type gin stand which can easily be inspected in an efficient and safe manner within the normal course of operation. The monitoring of the seed roll is desirable for prediction of irregularities that could significantly hamper the production of a ginning facility. This monitoring can take place by manual inspection with the eye or touch of the operator. In addition, this feature will facilitate the opportunity to introduce a new automatic process by which the control system can monitor the seed roll in order to improve overall productivity of the gin stand.

A method for estimating a temperature of a motor of a pitch drive mechanism of a rotor blade of a wind turbine includes monitoring, via at least one sensor, an actual temperature and at least one additional operating condition of the motor during a normal operating period of the wind turbine. The method also includes storing, via a pitch controller, the monitored temperatures and the monitored additional operating conditions of the motor for the normal operating period. Further, the method includes determining a relationship between the monitored temperatures and the monitored additional operating conditions of the motor for the normal operating period. Thus, in the event that the sensor fails to operate, the method includes determining, via the pitch controller, an estimated temperature of the motor based on the relationship.
