Product Description
The MAC090A-0-ZD-4-C/110-A-1/WR257XX/S001 is one of the motor models you can choose from Rexroth Bosch Indramat’s MAC090 AC family motor series. Motors from the MAC090 family series may have any of the following motor length sizes: A, B, or C. Out of these motor length classifications, class C motors are considered the largest. While class A and B motors have default lengths of 277 and 342 mm, MAC090 class C motors have a default length of 407 mm. This motor model takes advantage of air convection and radiation to cool the motor during operation.
The MAC090A-0-ZD-4-C/110-A-1/WR257XX/S001 features an insulation class F and IP65 protection. Motors with insulation class F have an insulation effective temperature of 155 degrees C. Meanwhile, a protection category of IP65 indicates that the motor is protected from splashes of water and from the intrusion of dust and other extrinsic objects. By implementing natural convection for cooling, Rexroth is able to make the MAC090A-0-ZD-4-C/110-A-1/WR257XX/S001 lightweight and compact. Although the nominal speed for this motor model is 2000 rpm, the motor functions well over a wide speed range. Before operating the MAC090A-0-ZD-4-C/110-A-1/WR257XX/S001 at a speed other than the nominal, make sure to consult the torque-speed characteristics for the MAC090A-0-Z under Rexroth’s MAC motor series manual.
Specifically, for the MAC090A-0-ZD-4-C/110-A-1/WR257XX/S001, the power connector is on side A, the side opposite the motor’s rear end. This motor model incorporates a standard blocking brake and motor feedback with an incremental or absolute encoder. The MAC090A-0-ZD-4-C/110-A-1/WR257XX/S001 also has a special option represented by the type code "S001". For Rexroth’s motor products, the type code “S001” indicates that the output shaft of the motor is equipped with a keyway following the requirements and specifications of DIN 6885.
