Abstract
A friction heated oven with a processing chamber in fluid communication with a heating blower, where the heating blower is operably coupled to a motor that may be fitted with a sensor adapted to measure a condition and a first controller coupled to the sensor, whereby the first controller generates an output signal received by a second controller, where the second controller is configured to adjust, based on the output signal, a maximum allowable rotational speed of the motor.
Claims20
A system, comprising:
- a processing chamber in fluid communication with a heating blower, wherein the heating blower is operably coupled to a motor;
- a sensor adapted to measure one or more conditions, wherein the one or more conditions comprise air viscosity;
- a first controller operably coupled to the sensor and adapted to receive the one or more conditions, wherein the first controller is configured to generate and send an output signal, wherein the output signal is based on the one or more conditions and a feedback received by the first controller, and wherein the feedback comprises torque output of the motor;
- and
- a second controller configured to receive the output signal, wherein the second controller is configured to adjust, based on the output signal, a maximum allowable rotational speed of the motor, wherein rotation speed of the motor is less than the maximum allowable rotation speed of the motor, and wherein the maximum allowable rotational speed prevents failure of the motor.

A method, comprising:
- (a) receiving, from a plurality of sensors, a first condition, wherein the first condition comprises viscosity of a fluid in a circulation corridor and a first power related feedback comprising torque output of a motor operatively coupled to a heating blower;
- (b) generating a first output signal, by a first controller, and based on at least a first algorithmic output that is a function of the first condition and the first power related feedback;
- (c) sending the first output signal to a second controller, wherein the first output signal correlates with a first maximum allowable rotational speed of the motor;
- (d) receiving, from the at least one sensor, a second condition, wherein the second condition is different than the first condition and a second power related feedback, wherein the second power related feedback is different than the first power related feedback;
- (e) generating a second output signal, by the first controller, and based on a second algorithmic output that is a function of the second condition and the second power related feedback;
- (f) sending the second output signal to the second controller, wherein the second output signal correlates with a second maximum allowable rotational speed of the motor, which is greater than the first maximum allowable rotational speed wherein rotation speed of the motor is less than the second maximum allowable rotation speed of the motor and wherein the first maximum allowable rotational speed and the second maximum allowable rotational speed prevent failure of the motor.
