Latest Patents

Among his latest patents, Nisley has developed a unique **synchronous motor with a soft start element**, which is strategically formed between the motor rotor and the motor output shaft. This design enables the motor to synchronize loads that have high inertia and/or high torque. The line-start synchronous motor boasts a housing, a rotor shaft, and an output shaft. The soft-start coupling portion is pivotal as it allows the synchronous motor to achieve synchronous operation, driving loads at near synchronous speed during normal steady-state operation. This innovation is particularly beneficial when the motor is connected to loads that would typically hinder normal synchronous operation.

Another notable patent focuses on an **elastomeric coupling having a clamp ring with flanges** that provide desired torsional stiffness characteristics. This coupling efficiently transmits torque between approximately aligned shafts while maintaining a center axis. The elastomer material used in the center element, along with the strategically designed clamp rings, ensures robust performance and adaptability, allowing for tailored torsional stiffness based on application requirements.
