Product Description
Specifically designed for rapid-response applications, the MAC092B-0-QD-4-C/095-B-1/WI553LV is one of the product models that you can get from Rexroth’s MAC AC motor series. With its QD-winding type, this motor model reaches a base speed of 2000 rpm, or 209.44 rad/s. Like other MAC AC motors, this model facilitates motor cooling through air convection. Cooling via natural convection is the simplest cooling mechanism for motors because it does not require the installation of additional fan units or an external cooling system. However, the drawback for natural-cooled motors is that they have the longest thermal time constant, which implies a longer cooling time after operation.
The MAC092B-0-QD-4-C/095-B-1/WI553LV also has advanced Tacho voltage feedback with a standardly mounted incremental encoder. For MAC motors, the Tacho feedback usually works with a separate controller, which allows precise adjustment of motor operating parameters. During the starting condition, the rotor does not move yet. During this condition, the motor parameters, such as the torque and the current, spike at a higher value. The higher values during this operating mode provide a basis for sizing the system protection scheme. Particularly for the MAC092B-0-QD-4-C/095-B-1/WI553LV, the starting torque and current are 7.2 Nm and 11.9 A, respectively. In certain applications, the motor model may operate at a maximum current of 17.4 A. For applications requiring greater torque or power, higher current values are desirable. Both the torque and the power increase proportionally with the motor current. ||| The MAC092B-0-QD-4-C/095-B-1/WI553LV has a standard centering diameter that spans a length of 95 millimeters. The power connector for this motor model is on side B. The MAC092B-0-QD-4-C/095-B-1/WI553LV also features a standard blocking brake with a maximum holding torque of 6.5 Nm.
