DB Series Motor Bracket

DB Series Motor Bracket

Product Description

The DB Series Motor Bracket (Stepper Motor Mounting Seat) is an integrated mounting solution designed to precisely position and align stepper motors within linear motion and CNC systems. These brackets serve as a rigid structural bridge, connecting NEMA-standard stepper motors directly to drive shafts, lead screws, or ball screw assemblies.

Engineered for Standard Frame Sizes
The DB Series is designed to accommodate various industry-standard stepper motor frame sizes, including:
DB42: Optimized for NEMA 17 motors.
DB57: Optimized for NEMA 23 motors.
DB86: Optimized for NEMA 34 motors.
DB110: Optimized for NEMA 42 motors.
DB130: Designed for 130-frame stepper motors.

Precision & Alignment Stability
Each bracket features precision-machined reference surfaces that minimize concentricity and alignment errors. This robust design dampens rotational vibration and supports highly stable performance under high-torque operating conditions.

Key Features & Engineering Advantages
1.Broad NEMA Compatibility: Standardized mounting patterns align with various stepper motor frames, from NEMA 17 up to NEMA 52 equivalents (DB42, DB57, DB86, DB110, and DB130).
2.Concentric Center-Bore Alignment: The pilot bore (centering ring) is machined to precise tolerances to maintain accurate concentricity between the motor shaft, the flexible coupling, and the driven shaft.
3.High-Rigidity Construction: Thick-walled cast iron, steel, or aluminum alloy construction minimizes torsional flexing during rapid acceleration and deceleration cycles.
4.Integrated Coupling Chamber: A hollow internal cavity accommodates standard flexible couplings (such as jaw, disc, or bellows types) to seamlessly link the motor to the driven axis.
5.Corrosion-Resistant Surface: Finished with black electrophoresis, powder coating, or anodization to protect against rust and wear in typical industrial workshop environments.
