US Patent:

20230018836, Jan 19, 2023

Filed:

Sep 20, 2022

Appl. No.:

17/948609

Inventors:

- Nashville TN, US
Thomas K. Best - Ft. Collins CO, US
Brian Alexander Lesniak - Nashville TN, US
Thomas Ray Hendrix - Annona TX, US
Michael Wayne Sprengel - Ft. Collins CO, US

International Classification:

F28F 27/00
F04D 27/00
F04D 25/08

Abstract:

A fan brake system for controlling an industrial fan system, the fan brake system including a fan brake having a brake pad movable on the fan brake to selectively engage the fan system. An actuator including a motor can be operable to cause the fan brake to perform a braking procedure on the fan system to resist rotational movement of the fan system. A controller can be communicated with the actuator, the controller operable to selectively cause the actuator and the fan brake to perform the braking procedure, wherein the controller is operable to monitor and control power being supplied to the motor of the actuator during the braking procedure to maintain a torque output of the motor according to a predetermined torque profile during the braking procedure.

International Classification:

H02P 3/26
F04D 19/00
F16D 65/16
F16D 55/22

Abstract:

A control system for mechanical braking devices is provided. The control system is designed to selectively slow, stop, and lock in place rotating machinery that is turning at an RPM that may be much greater than zero while helping minimize shock load on the rotating machinery. A fan brake control system is provided which can include: a fan brake; a position sensor; a microcontroller; an actuator; an operator interface; and a fan motor interface.
