SOYA NEMA 34 IP65 Waterproof Closed-Loop Motor Series

Achieve maximum precision and rigid environmental protection with the high-power SOYA NEMA 34 series IP65 waterproof closed-loop hybrid stepper motor. Featuring a fully sealed 86mm square enclosure and an impressive 8.5N.m holding torque, this advanced hybrid servo system provides total defense against dust ingress and liquid spray. By combining industrial-grade washdown reliability with real-time encoder positioning tracking, it serves as the ultimate motion drive for volatile manufacturing conditions.

Key Protection Features

Fully Sealed IP65 Rated Enclosure

Provides total protection against ingress of dust particles and reliable resistance to low-pressure water jets projected from any direction.

Closed-Loop No Position Loss

Integrates a heavy-duty waterproof encoder tracking feedback loop to completely eliminate step errors under volatile machine load shifts.

Sealed Moisture-Proof Assembly

Features an advanced protective shaft oil seal along with tightly double-sealed laminations to thoroughly prevent inner internal humidity penetration.

Robust Anti-Corrosion Spray Coating

Encased in a heavy wear-resistant structural housing that easily tolerates demanding chemical washdowns and high-humidity automation work.
