The MAC114A-0-ED-2-C/180-A-0/S009 is a cutting-edge AC motor produced by Rexroth Bosch, notable for its superior smooth-running properties due to the distinctive design of its stator combined with an advanced high-resolution tacho feedback mechanism. Belonging to the MAC series, this motor comes in two variants, one capable of lower speed and load, and another designed for handling considerable loads. Yet, the standard size 114 A MAC motor relies on natural convection for cooling, reserving forceful cooling techniques for its more load-bearing counterparts. Interestingly, its thermal processes follow an exponential pattern, with a thermal time constant of approximately 75 minutes, which allows the motor to reach about 63% of its normal temperature. The standard use ED-type winding precludes its utilization in operations requiring predominantly smooth run quality. The device’s tacho feedback helps maintain consistent motor speed by aiding the controller in responding effectively to load variations. The 180 mm pilot diameter reduces vibration, enhancing the rotor’s smooth operation. The motor also demonstrates high repetition rates and steady start-stop performance due to its high cyclic load capacity and electronic commutation, ensuring optimum productivity. However, the absence of an in-built holding brake limits it to simpler operations.
