Product Description:

Pacific Scientific's POWERPAC™ HYBRIDS Basic Series SN33HLYY-LNK-NS-01 motor provides durability and accuracy for demanding applications.

It adheres to industry standards for NEMA 33 frame size installation. The "H" version of this motor meets leading industry standards in speed and energy efficiency through its advanced design. The motor features a 4-lead configuration marked as LY in its model number, allowing users to connect power feeds easily and integrate the motor into various systems without issues. This product design omits NS feedback to maintain simplicity and straightforwardness without encoder or sensor technology. This motor model SN33HLYY-LNK-NS-01 includes built-in lead connections (LNK) that enhance wiring security and extend motor life. The shaft modification code 01 denotes a standard motor with a shaft seal to protect against external particles and lengthen its operational run time. This motor operates within a power range of 5A per phase, similar to other motors in the POWERPAC™ product line. Under typical temperature conditions, this motor performs optimally with windings designed for 130°C operation and can run continuously while exposed to room air at 40°C.

At 1 kHz with 1 amp, we measure the small signal inductance characteristic of all series members in this product line. Motor testing assesses thermal resistance when mounted in still air to verify durability under various heat conditions. The POWERPAC data aligns well with holding torque data ranging between 845 oz-in and 1580 oz-in, ensuring reliable performance under diverse loading conditions. The 2.5 oz-in detent torque feature facilitates precise control and reduces accidental movements for this SN33HLYY-LNK-NS-01 motor. The product remains operational in vibration levels of up to 2.5G, making it suitable for applications requiring vibration tolerance due to extreme environmental conditions.
