Secure ultimate positioning vertical safety and eliminate heavy load drops with the industrial SOYA NEMA 23 series hybrid stepper motor with electromagnetic brake. Featuring a standard 57mm square frame size with flexible stack lengths up to 3.2N.m, this advanced actuator integrates a heavy-duty 24V DC fail-safe holding brake. When power is removed, the friction brake engages instantly to secure the motor shaft firmly against gravity or sudden external impacts, providing robust zero-drift motion protection for volatile industrial vertical axes.
Spring-set mechanical brake locks the rotative axis automatically during power loss, providing reliable position holding without drop risks.
Heavy-duty friction pad structure grips the main shaft assembly tightly with zero backlash, entirely eliminating fine creeping position drift.
Specially engineered to perfectly manage Z-axis structural loads and linear screw setups in heavy multi-axis CNC automated workstations.
The electromagnetic brake module comes pre-assembled straight from our factory floor, requiring zero extra customer alignment operations.

Our roots go back to 2002 as “Songya Motor Control Factory”. In 2017, we incorporated as Changzhou Songya Electromechanical Co., Ltd., marketing our systems worldwide under our registered brand SOYAMOTOR. Leveraging over 20 years of deep expertise in stepper, servo, and brushless motor manufacturing, we design and produce a comprehensive range of premium CNC digital cutting tools on our own shop floor. Beyond oscillating knives, our in-house production includes servo oscillating knives, drag knives, kiss-cut knives, creasing wheels, rotary knives, V-cut tools, and punching tools—delivering factory-direct precision with 100% traceable quality.
