Product Description:
The model TT-4209-3000-B is a Direct Drive DC Torque Motor designed by Kollmorgen for servo applications. It attaches directly to the load that eliminates the need for gear reduction. It delivers high torque at low speeds and ensures precise motion control.
The TT-4209-3000-B DC motor operates at a continuous stall voltage of 13 V and can handle up to 59 V peak at stall. It draws 24.4 A under continuous conditions and up to 120 A peak current. It produces 22 lb-ft continuous torque and reaches up to 95 lb-ft peak torque. The motor achieves a maximum operating speed of 3000 RPM. Integrated resolver feedback in this motor provides precise position information that is critical for closed loop control systems. Its low electrical time constant allows quick motor response across a broad speed range. This is achieved through low armature inductance thanks to design features like high core saturation and numerous poles. The torque output of the motor is highly linear with input current across all speeds and angles. This ensures no dead zones or non linear behaviors during low excitation that allows accurate control.
The TT-4209-3000-B DC motor from the Inland Direct Drive Motor series features flange mounting that enables secure and straightforward attachment in industrial systems. Its construction reduces mechanical backlash that increases servo stiffness and mechanical resonance frequency. The motor is also designed for smooth and quiet operation especially at lower speeds. This is made possible by the use of many slots per pole that minimizes cogging and enables stable low speed performance. The motor is ideal for precision motion systems requiring reliable and responsive torque control with high torque density and consistent feedback.
