Product Description:
Pacific Scientific manufactures the SN34HLYY-LNK-NS-00 servo motor. The SN34HLYY-LNK-NS-00 servo motor from Pacific Scientific is an industrial automation motor. It has a NEMA 34 frame, which is 3.38” square. This frame size is key for mechanical compatibility and uniform installation in industrial machines. The motor can be easily swapped or added to new designs due to its physical dimensions, which also determines how it fits into existing systems. Standardizing frame size has a direct impact on the mechanical stability and heat dissipation of the motor, so it’s important for system design and maintenance. The motor has a four-lead parallel connection and H-type winding. This setup maximizes torque and minimizes resistive losses for the best electrical performance. The torque speed characteristics of the motor are directly affected by the H-type winding coil design, which controls the magnetic field distribution.
The motor’s efficiency and dynamic response are determined by the electrical characteristics of the windings, such as resistance and inductance. The motor’s ability to handle sudden current changes is affected by the small signal inductance, which is measured at 1kHz and represented in millihenries (mH). The LNK termination makes installation easier and more reliable by being designed to connect directly to terminal boards or MS connections. By ensuring stable and secure electrical contact, this termination method reduces connection problems. The termination material and shape affect the electrical resistance and heat dissipation of the connection point. The whole system efficiency is increased by this standardized connection which also reduces installation time and wiring complexity. Without a heat sink, the motor can run up to 40°C ambient and the windings are rated up to 130°C. This thermal rating is key to ensure the motor’s life and reliability under various operating conditions.
The motor’s heat dissipation is indicated by its thermal resistance, which is in °C/W. This is to avoid thermal runaway and ensure steady operation. The “NS” designation means the motor does not have an encoder. So, it does not provide position or speed feedback. This simplifies the control system, reduces cost, and is good for applications where closed-loop control is not required. Without an encoder, feedback signal processing is not required, which reduces system complexity and computational load. The straight key shaft arrangement allows for standard mounting, which means it’s compatible with various mechanical connections. The shaft’s ability to transfer torque without deformation is determined by its mechanical properties. The motor’s suitability for a given application is mainly determined by its holding torque, which is unique to NEMA 34 motors, and current rating, which is set for best performance within the POWERPACTM hybrid requirements.
