12 N·m Stepper Motor With Brake - Compact NEMA 42 with 17-bit Encoder

12 N·m Stepper Motor With Brake in a Compact 135 mm Body

The 110J12135EC-17BC-SC pairs a compact 135 mm NEMA 42 body with 12 N·m holding torque and an integrated brake. It draws 4.5 A per phase on a 19 mm shaft and is designed for axes that need the stiffness of the 110 mm frame, moderate current, and the security of a mechanical hold when power is removed.

Locked Between Cycles

With the brake engaged on power loss, the axis cannot sag under gravity or be displaced by process forces during idle periods. During motion the brake releases, and the closed loop drive manages positioning with 17-bit encoder feedback.

Operating Profile

Phase current is 4.5 A, which keeps the drive requirement moderate while maintaining high torque for the frame size. The motor runs with low noise and low vibration, and the closed loop gives a fast response to command changes.

Specifications

• Motor type: 3-phase hybrid stepper, closed loop, with brake
• Frame size: NEMA 42
• Body length: 135 mm
• Phase current: 4.5 A
• Holding torque: 12 N·m
• Shaft diameter: 19 mm
• Feedback: integrated 17-bit encoder

Suggested Applications

Packaging machinery indexing, CNC tool changers, and automated handling stations where space is tight and loads must stay put between cycles. The brake and 17-bit loop make this 12 N·m Stepper Motor With Brake a strong fit for heavy-load rotary table indexing and vertical CNC axis moves. Lyenwsin provides this motor with compatible drives and support.

Retrofit Notes

Because the body is only 135 mm long, it replaces longer motors in existing machines without major bracket changes. Confirm the brake supply wiring and the encoder interface before ordering. The 4.5 A current keeps the retrofit within the capability of most NEMA 42 closed loop drives. For machines with gravity-loaded tool changers, the brake ensures the tool arm cannot fall during a power loss.
