Product Description
The MAC071C-0-GS-4-C/095-B-2/WA608XX/S001 is a product variation under the MAC AC servo motor series by Rexroth. Specifically, this product model originated from the MAC071 family with a frame size of C. It employs natural convection for cooling, which allows the motor to maintain its lightweight construction and original motor dimensions. This motor model has a winding designation of GS and a feedback type of 4. MAC AC motors that come with a feedback type of 4 employ Tacho voltage feedback with an integrated incremental or absolute encoder. For this motor, the Tacho generator uses standard mounting. The MAC071C-0-GS-4-C/095-B-2/WA608XX/S001 has a 95-mm centering diameter, which is the only diameter applicable for motors of size C under the MAC071 family.
The MAC071C-0-GS-4-C/095-B-2/WA608XX/S001 has a rated speed of 6000 rpm, a maximum torque of 18.1 Nm, and a stall torque of 6.6 Nm. These parameters are important for analyzing the MAC071C motor characteristics under Rexroth’s MAC AC manual. Based on Rexroth’s documentation, the MAC071C-0-GS-4-C/095-B-2/WA608XX/S001 has different breaking points depending on the type of bus voltage provided. At a type 1 bus voltage (10% overvoltage), the breaking point of this motor model is 6400 rpm. At the nominal bus voltage, the breaking point approaches the nominal speed. Meanwhile, at a type 3 bus voltage (10% undervoltage), the motor’s breaking point is 5000 rpm. The motor’s breaking point describes the operating speed at which the torque falls from its maximum value.
Referring to its mechanical load characteristics, the MAC071C-0-GS-4-C/095-B-2/WA608XX/S001 has a maximum radial load tolerance of 550 N at the nominal speed. Maintaining the nominal speed, the equivalent maximum axial load tolerance of this motor model is 275 N, which is half the maximum radial load.
