A Servo Motor Mounting Bracket is CNC-machined to achieve flatness within 0.01 mm and angularity within 0.02°, ensuring orthogonal and planar alignment between the servo motor shaft and the driven assembly. Such precision is necessary for preventing shaft misalignment, which leads to uneven load distribution, excessive bearing wear, and encoder inaccuracies. The bracket establishes a repeatable mechanical datum, eliminating field rework and ensuring alignment consistency across multiple installations.
Under torque loads and inertial forces, the Servo Motor Mounting Bracket serves as a load transfer medium, routing axial and radial forces into the machine frame. Bracket geometry is developed through FEA to prevent local stress concentrations, particularly around mounting holes and overhung sections. Load paths are optimized by introducing structural reinforcements that maintain dimensional integrity under full acceleration and deceleration phases, critical for preserving servo axis linearity and gear mesh stability.
The Servo Motor Mounting Bracket must maintain positional fidelity under thermal cycling, especially in enclosures or systems with high heat generation. Material selection is based on thermal compatibility with the servo housing, using 6061-T6 aluminum or normalized low-carbon steels to ensure matched coefficients of thermal expansion. Final machining is performed after thermal stabilization to avoid internal stress-induced warping, preserving tight tolerances over time and across temperature gradients.

Holds servo motors in precise alignment for synchronized multi-axis travel in Cartesian systems used for material handling or packaging automation.
Supports vibration-isolated servo placement to eliminate positional drift and ensure consistent alignment in machine vision and inspection systems.
In high-speed servo applications, the Servo Motor Mounting Bracket plays a key role in isolating and attenuating vibrational energy. The bracket’s mass and geometry are tuned using modal analysis to shift its natural frequency outside the servo operating range, typically 2–3 octaves above expected harmonics. This prevents vibration-induced resonance, encoder signal distortion, and mechanical fatigue in lightweight or cantilevered motor setups, thereby increasing system stability and feedback fidelity.
The Servo Motor Mounting Bracket is designed with integrated dowel pin bores, pilot diameters, or face registers held within ISO H7/h6 fits to ensure accurate positioning during motor installation. This precision eliminates reliance on bolt torquing to achieve alignment, reducing cumulative assembly errors in multi-axis systems. Kinematic constraint principles are applied to limit degrees of freedom and ensure consistent axial and radial positioning under both static and dynamic conditions.

Frigate machines all bracket surfaces using multi-axis CNC centers with dual-plane referencing to maintain tight geometric tolerances. Parallelism between mounting faces is held within ±0.01 mm across all critical planes. This prevents angular misalignment between the motor shaft and driven axis during motion. Such control is essential in servo-driven stages requiring micron-level travel accuracy.
Frigate performs modal and harmonic analysis on each bracket to determine its natural frequency. Bracket mass and rib geometry are adjusted to shift resonance outside the servo’s operational range. Material damping properties are also considered based on expected RPM and duty cycle. This reduces feedback-induced oscillations in high-precision servo loops.
Frigate selects bracket materials with coefficients of thermal expansion closely matched to the servo motor casing. Components are stress-relieved and finish-machined post-treatment to eliminate internal distortions. Mounting hole locations are designed with expansion gaps where required to absorb thermal shift. These steps prevent misalignment in temperature-fluctuating environments.
Frigate designs include adjustable slot paths for fine-tuning belt tension without distorting the motor mounting plane. Brackets are reinforced near tension points to resist deflection under dynamic belt loads. Center distance calibration marks are also machined for repeatable setup. This ensures smooth torque transfer and reduces wear on pulley components.
Frigate holds dowel pin holes to ISO H7/h6 fits using in-process probing and post-machining CMM verification. Hole locations are referenced from the primary mounting face, not from unmachined stock. This ensures exact motor placement even after repeated assembly cycles. Precision locating eliminates shift under load or thermal expansion.
