Product Description:
The TTB2-2933-3020-HA is a direct-drive motor with an integrated planetary gearhead, supplied by Kollmorgen as part of the Inland Direct Drive Motors series. In automated machinery, this assembly converts servo control commands into precise, low-backlash rotary motion at the load flange, allowing machine builders to position indexing tables, pick-and-place heads, or conveying elements without separate belt reductions. The matched gear section multiplies output torque while the motor section maintains a high dynamic response, avoiding couplings that can add compliance to multi-axis systems.
Inside the gear stage, the reduction ratio is 10:1, so the load completes one revolution for every ten motor turns; this ratio increases output torque and lowers the inertia reflected to the motor. The gearhead has a moment of inertia of 0.075 kg-cm², minimizing the required servo gain adjustments when the unit is paired with a low-inertia rotor. The gear module measures 2.68 in from the mounting face to the flange, keeping the assembly compact. With a mass of 4.2 lb, the unit adds relatively little weight to moving carriages or end-of-arm tools. Power is transmitted through a ground and hardened shaft with a diameter of 0.5000 in, matching common clamp couplings and collets. These dimensions support installation in machinery with limited mounting space while preserving a rigid connection to the driven load.
The gearing can withstand transient torque of 79.1 Nm, allowing the system to accommodate fast accelerations or emergency stops. Under continuous duty, the assembly delivers 26.9 Nm at 1,000 rpm, while it provides 21.7 Nm at speeds up to 4,000 rpm for high-speed indexing applications. The gearhead has a torsional stiffness of 1.9 Nm/arc-min, helping commanded movements settle quickly and maintain position against process forces. This stiffness also reduces angular deflection when the direction of rotation changes. The available torque range supports repetitive motion in packaging equipment, semiconductor handling systems, and small-format machining centers.
