Product Description:
Rexroth Bosch’s MRS312H-2N-0130-NNNN is a top product under the IndaDyn H motor series. Particularly, it is designated as a rotor model that works seamlessly with various MSS stators under the same product line. Featuring a robust body frame and a thermally stable construction, this rotor is appropriate for large applications that require a high driving torque. At its recommended DC bus voltage, the MRS312H-2N-0130-NNNN achieves a nameplate speed of 250 to 800 rpm, depending on the MSS stator used. Regardless of the stator used, however, the MRS312H-2N-0130-NNNN can transmit a nameplate torque of around 1,100 to 1,125 rpm.
The MRS312H-2N-0130-NNNN features a 2N construction class, allowing it to fit with the shaft securely. Considering its relatively small frame and construction type, the MRS312H-2N-0130-NNNN has a rotor moment of inertia of 1.146 kg(m^2) and achieves its steady-state temperature in 13 minutes. Without the MSS stator, this product model weighs 95.6 kilograms and operates at an ambient temperature range of 0 to 40 degrees Celsius. Like all other MRS rotors, this product features an insulation class of F and a protection mode of IP 00. In general, compatible MSS stators for the MRS312H-2N-0130-NNNN employ seven pole pairs or 14 poles.
The MRS312H-2N-0130-NNNN has an internal diameter of 130 millimeters and an outer diameter of 215 millimeters. This rotor employs 12 fixing screws, spaced 30 degrees apart, and 24 M8 bolts for balancing. During operation, the MRS312H-2N-0130-NNNN benefits from the self-contained cooling system from the MSS stator. Like all other IndraDyn H products, the MRS312H-2N-0130-NNNN does not come with an encoder. For applications requiring an encoder, alternative options may be explored by attaching external devices. The MRS312H-2N-0130-NNNN comes with a special rotor warranty when purchased from Wake Industrial.
Frequently Asked Questions about MRS312H-2N-0130-NNNN:
Q: What MSS stators are compatible with the MRS312H-2N-0130-NNNN?
A: There are two main MSS stators that are compatible with the MRS312H-2N-0130-NNNN: the MSS312H-0025 and the MSS312H-0085.
Q: Which stator is better for the MRS312H-2N-0130-NNNN for high-speed applications, the MSS312H-0025 or the MSS312H-0085?
A: Between the MSS312H-0025 and the MSS312H-0085, the MSS312H-0085 can achieve a higher rated speed of 850 rpm. At most, it can achieve a maximum speed of 3400 rpm. For comparison, the MSS312H-0025 can only achieve a speed within the range of 250 to 1100 rpm.
Q: How many threaded pins are provided for the MRS312H-2N-0130-NNNN?
A: For rotor balancing, the MRS312H-2N-0130-NNNN comes with 8 M8x8 threaded pins and 8 M8x10 pins.
Q: What maximum torque can the MRS312H-2N-0130-NNNN achieve?
A: The MRS312H-2N-0130-NNNN can transmit a maximum torque of 2,750 rpm using either the MSS312H-0025 or the MSS312H-0085 stator.
Q: The MRS312H-2N-0130-NNNN can transmit a maximum torque of 2,750 rpm using either the MSS312H-0025 or the MSS312H-0085 stator.
A: The MRS312H-2N-0130-NNNN can safely be stored at a temperature range of -20 to 60 degrees Celsius.
