Product Description

IndraDyn H motors by Rexroth Bosch Indramat are preferable for their high output characteristics and self-contained cooling system. What sets IndraDyn H motors apart from other motor products by Rexroth is that it comes with a modular design, allowing customers to purchase the stator or rotor separately. Depending on the intended application, specific rotors may be more preferable. Larger applications usually need larger rotors that can withstand high radial and axial force requirements. Under the IndraDyn H product line, the MRS382F-2N-0230-NNNN rotor is derived. Specifically, this rotor is designed for stators with a 382F body frame. It features an internal diameter of 230 millimeters.

MRS motors may come with a plain drilling or a step interference fit to lock with the shaft. Particularly, the MRS382F-2N-0230-NNNN employs a step interference fit, which allows it to fasten to the shaft using a series of varying diameters. Compared to plain-drilled rotors, MRS units with a step interference fit are preferable for high-precision applications. The MRS382F-2N-0230-NNNN alone is a massive component, weighing about 120 kilograms without the stator. When paired with an MSS motor with a 382F frame, the net mass of both products is 382 kilograms. Considering the weight of this rotor, this unit is best for the heaviest applications and systems.

When excited by a standard supply voltage, the MRS382F-2N-0230-NNNN achieves a nameplate speed, torque, and power of 180 rpm, 2,170 Nm, and 40.9 kW. As a heavy IndraDyn H rotor, it can drive loads at a high torque output and maintain a synchronous speed with the stator. Like all other MRS rotors by Rexroth, it features an insulation class F, a protection mode of IP00, and a permissible operating range of 0 to 40 degrees Celsius.
