MRT110A-3C-0052-NNNN

Product Description:

Known for its very small construction, the MRT110A-3C-0052-NNNN is perhaps one of the most lightweight MRT rotors ever produced and commercialized by Rexroth Bosch Indramat. As part of the internationally recognized IndraDyn T synchronous series, this modular rotor unit serves as the primary component for driving loads in spindle applications. When paired with an appropriate MST stator, also under the IndraDyn T family, this rotor achieves its full potential and performs at a wide operating range. Similar to other IndraDyn T rotors under the MRT product class, this unit boasts a low rotor inertia and exhibits high torque output in its rated velocity.

Based on its type code, the MRT110A-3C-0052-NNNN has an internal diameter of 52 millimeters. The internal diameter for Rexroth’s IndraDyn T rotors influences its driving capabilities and speed characteristics. Usually, rotors with larger internal diameters are capable of withstanding higher radial and axial forces. Furthermore, larger internal diameters also provide higher torque output at their rated speed. Rotors with small internal diameters, like the MRT110A-3C-0052-NNNN, are preferable for consistent driving applications requiring relatively higher velocities. With a standard DC bus voltage of 540 V, the MRT110A-3C-0052-NNNN achieves its nameplate characteristics. For this product model, the rated values are equivalent to the standstill values since the rotor does not employ a keyway. With a higher DC excitation of 750 V, this rotor can achieve its maximum synchronous velocity.

At any point in time, the MRT110A-3C-0052-NNNN performs at its best when constrained at an ambient temperature window of 0 to 40 degrees Celsius. Although rotors are less sensitive to temperature changes compared to stators, it is important to avoid operating beyond the recommended temperature range.
