TT DC Geared Motor Bracket

A TT DC Geared Motor Bracket is a crucial hardware mounting accessory used to securely attach standard yellow TT (BO) plastic gearbox motors to a robot chassis or DIY project frame. They align perfectly with the pre-molded side-mounting holes of the motor body, eliminating the need for temporary fixes like zip ties or glue.

Common Types of Brackets

• Aluminum Alloy Brackets: The most popular option due to its extreme rigidity, lightweight profile, and resistance to vibration. These are typically block-shaped (approx. 22mm x 15mm x 5mm) and offer precise mechanical stability.
• Acrylic T-Shape Brackets: Frequently included in entry-level, laser-cut smart car kits. They offer basic, lightweight support but can be brittle under heavy loads or impacts.
• L-Shaped Corner Metal Mounts: Provide a heavy-duty, 90-degree vertical orientation. These are optimal if you need to attach the motor directly to a perpendicular plate or a CNC fixture.
• ABS Plastic Clip-On Brackets: Budget-friendly, snap-on alternative holders available in multiple colors, often utilized in STEM classrooms.

Standard Specifications

• Dimensions: Typically 22.5mm × 15.5mm × 5mm for the standard alloy block version.
• Screw Threading: Uses standard M3 threading for cross-body motor alignment.
• Typical Hardware Kit: Includes 2 long M3 bolts (around 30mm) to go completely through the TT motor casing and shorter M3 screws/nuts to lock the bracket down to the base chass.

Crucial Mechanical Functions:

• Vibration Dampening: Stops the motor from shifting or vibrating loose during high-torque startup periods.
• Perpendicular Alignment: Holds the drive shaft at exactly 90 degrees relative to the mounting surface for straight driving.
• Load Redistribution: Transfers structural weight away from the weak plastic motor tabs onto the main metallic or acrylic chassis.
• Easy Swapping: Allows quick removal of burned-out or stripped motors during competitions without damaging the robot frame.
