Title: David C. Wycoff: Innovator in Motor Control Technologies
Introduction
David C. Wycoff is a notable inventor based in Elm Grove, WI (US). He has made significant contributions to the field of motor control technologies, holding a total of 2 patents. His innovative work focuses on enhancing the efficiency and safety of hoist operations.
Latest Patents
Wycoff's latest patents include a "Method and apparatus for determining load holding torque." This invention discloses a motor control method where a drive motor is connected to an adjustable frequency power supply. The frequency of the power supplied to the motor can be selectively varied. At the initiation of a hoist operation, power is supplied to the motor at a predetermined low frequency, which is sufficient to provide load holding torque upon the release of the brake. The system senses the actual current level supplied to the motor and compares it with a reference signal to ensure safe operation.
Another significant patent is the "Method and apparatus for detecting deviation of motor speed." This invention describes an adjustable frequency motor drive system for a hoist, where the motor speed follows the varying frequency at a slip speed. The system ensures that the motor speed does not exceed a predetermined frequency value, thereby maintaining control over the hoist load. If the motor speed exceeds this value, an output signal is produced to apply a brake, stopping and holding the motor and hoist.
Career Highlights
Throughout his career, David C. Wycoff has worked with various companies, including Harnischfeger Corporation. His experience in the industry has allowed him to develop innovative solutions that address critical challenges in motor control.
